The anharmonic free energy of dynamically unstable systems can be accurately calculated by thermodynamic integration, if the configurational ensemble obeying the true potential is obtained. This usually requires computationally costly molecular dynamics (AIMD). The authors present here a way to accomplish this by direct statistical sampling of ensembles using interatomic force constants and without MD. Phase transition temperatures of binary shape-memory alloys are predicted to within 25% error at a speed-up of about three orders of magnitude over AIMD.

It is well known that in the 1D Anderson model, the system is always localized, regardless of how small the disorder strength is. Here, the authors demonstrate that by replacing the standard onsite disorder term, , with a nodal disorder term, , where , the system becomes superdiffusive. The nodal disorder introduces a node in momentum space, resulting in a divergence of the localization length at the nodal momentum. This divergence in localization length induces superdiffusive transport.

The authors report here pressure-enhanced antiferromagnetic (AFM) order in DySbTe single crystals. As pressure increases beyond 15 GPa, the resistivity shows a distinct upturn, indicating a strengthened AFM transition near 9 K. Concurrently, magnetotransport measurements reveal shifts in spin-flop and spin-flip transitions, highlighting the complex relationship between pressure, magnetism, and electronic transport in this topological material.

Altermagnets feature vanishing net magnetization, similar to antiferromagnets, but exhibit time-reversal symmetry breaking and spin-split band structures. This work constructs minimal models for altermagnetism based on symmetry arguments considering two magnetic atoms in the unit cell and demonstrates that these can capture key properties of the band structure and altermagnetic spin splitting for the material candidate RuO. Notably, the models have altermagnetic ground states and give rise to a Berry curvature and a conductivity linear in the spin-orbit coupling.

Here, the authors introduce two Heisenberg models for -wave altermagnets, namely the checkerboard model and model adapted to rutiles. Both models capture the altermagnetic properties of the magnon spectra and allow one to analyze transport and thermodynamic phenomena in -wave altermagnets. The main prediction is a piezomagnetism driven by the thermal fluctuations, i.e., the appearance of the perpendicular magnetization in response to in-plane stress that only arises once temperatures reach a sizable fraction of the magnetic transition temperature. The authors further predict a thermal spin conductivity, i.e., generation of a spin current in response to an applied temperature gradient.

Magnetic nanoparticles can be synthesised in a wide range of shapes, which greatly impacts their utility as heating agents. Here, the authors use Langevin dynamics simulations of spheroidal particles to study how their shape affects both the net energy absorption and whether the energy is dissipated by viscous friction or magnetic losses. This study establishes a procedure for maximising the absorption rate in a given applied field via particle shape.

In antiferromagnets, spin dynamics can occur at terahertz (THz) frequencies, but the energy-efficient excitation of antiferromagnetic magnons is challenging. Here, the authors describe the Néel vector oscillations induced by acoustic pulses injected into NiO films. Using advanced micromagnetoelastic simulations, they show that picosecond bipolar pulses can efficiently create antiferromagnetic standing spin waves in the single-crystalline NiO films. The results significantly advance both antiferromagnetic magnonics and straintronics by clarifying conditions for the purely magnetoelastic generation of THz magnons and revealing strong strain effects on the spin-wave dispersion in NiO.

Detection of long-distance magnon transport in antiferromagnets is challenging due to domain wall scattering, robustness against magnetic fields, and anisotropy dependent excitation modes. The authors demonstrate here both electrically and thermally generated magnons in the easy-plane antiferromagnet and multiferroic SrMnO, persisting up to long distances of 2.3 µm, and discuss this in the framework of rotating manipulated Néel vectors and occupancy of magnon modes. This work establishes the potential of such easy-plane antiferromagnets as conductor of magnon currents over long distances.

Time-reversal symmetry breaking in the superconducting state is pondered to occur in superconductors having anisotropic or multi-band energy gap, or - and -wave pairing superconductivity of unconventional character. Using the muon spin relaxation and rotation technique, here the authors detect the spontaneously generated internal magnetic field that evidence the occurrence of time-reversal symmetry breaking in the superconducting state of a conventional single-band -wave superconductor CaPdAs. They also demonstrate that the energy gap structure of CaPdAs is isotropic.

Superconductors often host multiple competing and intertwined orders, such as spin and charge density waves. Recent scanning tunneling microscopy measurements suggest that the heavy-fermion superconductor UTe has both Cooper pair and charge density waves (PDWs and CDWs, respectively). Using high-resolution resonant ultrasound spectroscopy, the authors find here no evidence for a thermodynamic phase transition to a bulk CDW state, also ruling out a bulk PDW. These measurements highlight the need to distinguish between bulk and surface physics in UTe.

The type of superconducting pairing symmetry realized in recently discovered kagome metals remains an open question at present. Here, the authors theoretically investigate the spin-lattice relaxation rate of unconventional superconductivity on the kagome lattice, and demonstrate the existence of a Hebel-Slichter peak for -wave superconductivity. They explain this result from a peculiar sublattice interference effect present on the kagome lattice. This study shows the surprising effect that unconventional kagome superconductors can behave similar to conventional -wave superconductors.

Understanding the dynamics of vortices in superconductors is crucial in two dimensions, since these materials are expected to undergo a topological Berezinskii-Kosterlitz-Thouless (BKT) phase transition. It has remained challenging, however, to directly fingerprint this transition and the associated vortex dynamics. Here, the authors show that spin qubit noise magnetometry can potentially detect signatures of the BKT transition via its impact on the magnetic flux noise emanating from the sample as a function of frequency, temperature, and distance.

The pair density wave (PDW), arising from an interplay between coexistent superconductivity and charge density wave (CDW) order, is a phase of matter in which the superconducting order parameter is modulated in real space. Recently, signatures of PDWs were reported in the unconventional superconductor UTe through surface-sensitive probes. This paper investigates the question of whether CDW order exists in the bulk of UTe using low-temperature synchrotron x-ray diffraction. The authors find no direct evidence of CDW ordering in the diffraction pattern and place an upper bound on the charge density amplitude. The results indicate that the CDW and, by extension, the PDW, observed in previous studies of UTe are likely confined to its surface.

The universality class of the measurement-induced phase transition changes significantly when a diffusing conserved density is present. The authors analytically show here the impact of diffusive correlations, supported by numerical results from a new model that couples conserved densities into Clifford circuits through projective measurements. Rare-region effects away from the critical point are also explored. This result extends to monitored circuits with symmetry.

A complete theory of the orbital magnetic susceptibility of an isolated multiband electron system was developed in 2015. Here, the authors study whether one can control this orbital susceptibility by opening the electron system to a fermionic bath. They show that, as the system-bath coupling is increased, a properly engineered bath can enhance the diamagnetic susceptibility of the system and even change its orbital paramagnetic response into a diamagnetic one. The work also discusses how a Van Hove singularity in the bath density of states can be exploited to generate a giant enhancement of the orbital magnetic response. These results are counterintuitive, relative to the common belief, that bath-induced decoherence merely leads to the quenching of the orbital magnetic susceptibility.

Due to its magnetostructural phase transition, MnAs is a paradigmatic material for studying the strong coupling between lattice and magnetism. Here, the authors explore the subpicosecond magnetic and structure dynamics of MnAs following laser excitation in order to test the transition mechanisms proposed in the literature. Time-resolved x-ray diffraction measurements reveal a differentiation of Mn and As atomic disorder relaxation times in the ferromagnetic phase that is absent in the paramagnetic phase. These results strongly support the predictions of recent density functional theory calculations.

This work constructs minimal models for altermagnetism based on symmetry arguments considering two magnetic atoms in the unit cell and demonstrates that these can capture key properties of the band structure and altermagnetic spin splitting for the material candidate RuO. Notably, the models have altermagnetic ground states and give rise to a Berry curvature and a conductivity linear in the spin-orbit coupling.

Here, the authors introduce two Heisenberg models for -wave altermagnets, namely the checkerboard model and model adapted to rutiles. Both models capture the altermagnetic properties of the magnon spectra and allow one to analyze transport and thermodynamic phenomena in -wave altermagnets. The main prediction is a piezomagnetism driven by the thermal fluctuations, i.e., the appearance of the perpendicular magnetization in response to in-plane stress that only arises once temperatures reach a sizable fraction of the magnetic transition temperature. The authors further predict a thermal spin conductivity, i.e., generation of a spin current in response to an applied temperature gradient.

Magnetic nanoparticles can be synthesised in a wide range of shapes, which greatly impacts their utility as heating agents. Here, the authors use Langevin dynamics simulations of spheroidal particles to study how their shape affects both the net energy absorption and whether the energy is dissipated by viscous friction or magnetic losses. This study establishes a procedure for maximising the absorption rate in a given applied field via particle shape.

In antiferromagnets, spin dynamics can occur at terahertz (THz) frequencies, but the energy-efficient excitation of antiferromagnetic magnons is challenging. Here, the authors describe the Néel vector oscillations induced by acoustic pulses injected into NiO films. Using advanced micromagnetoelastic simulations, they show that picosecond bipolar pulses can efficiently create antiferromagnetic standing spin waves in the single-crystalline NiO films. The results significantly advance both antiferromagnetic magnonics and straintronics by clarifying conditions for the purely magnetoelastic generation of THz magnons and revealing strong strain effects on the spin-wave dispersion in NiO.

Detection of long-distance magnon transport in antiferromagnets is challenging due to domain wall scattering, robustness against magnetic fields, and anisotropy dependent excitation modes. The authors demonstrate here both electrically and thermally generated magnons in the easy-plane antiferromagnet and multiferroic SrMnO, persisting up to long distances of 2.3 µm, and discuss this in the framework of rotating manipulated Néel vectors and occupancy of magnon modes. This work establishes the potential of such easy-plane antiferromagnets as conductor of magnon currents over long distances.

Time-reversal symmetry breaking in the superconducting state is pondered to occur in superconductors having anisotropic or multi-band energy gap, or - and -wave pairing superconductivity of unconventional character. Using the muon spin relaxation and rotation technique, here the authors detect the spontaneously generated internal magnetic field that evidence the occurrence of time-reversal symmetry breaking in the superconducting state of a conventional single-band -wave superconductor CaPdAs. They also demonstrate that the energy gap structure of CaPdAs is isotropic.

Superconductors often host multiple competing and intertwined orders, such as spin and charge density waves. Recent scanning tunneling microscopy measurements suggest that the heavy-fermion superconductor UTe has both Cooper pair and charge density waves (PDWs and CDWs, respectively). Using high-resolution resonant ultrasound spectroscopy, the authors find here no evidence for a thermodynamic phase transition to a bulk CDW state, also ruling out a bulk PDW. These measurements highlight the need to distinguish between bulk and surface physics in UTe.

The type of superconducting pairing symmetry realized in recently discovered kagome metals remains an open question at present. Here, the authors theoretically investigate the spin-lattice relaxation rate of unconventional superconductivity on the kagome lattice, and demonstrate the existence of a Hebel-Slichter peak for -wave superconductivity. They explain this result from a peculiar sublattice interference effect present on the kagome lattice. This study shows the surprising effect that unconventional kagome superconductors can behave similar to conventional -wave superconductors.

Understanding the dynamics of vortices in superconductors is crucial in two dimensions, since these materials are expected to undergo a topological Berezinskii-Kosterlitz-Thouless (BKT) phase transition. It has remained challenging, however, to directly fingerprint this transition and the associated vortex dynamics. Here, the authors show that spin qubit noise magnetometry can potentially detect signatures of the BKT transition via its impact on the magnetic flux noise emanating from the sample as a function of frequency, temperature, and distance.

The pair density wave (PDW), arising from an interplay between coexistent superconductivity and charge density wave (CDW) order, is a phase of matter in which the superconducting order parameter is modulated in real space. Recently, signatures of PDWs were reported in the unconventional superconductor UTe through surface-sensitive probes. This paper investigates the question of whether CDW order exists in the bulk of UTe using low-temperature synchrotron x-ray diffraction. The authors find no direct evidence of CDW ordering in the diffraction pattern and place an upper bound on the charge density amplitude. The results indicate that the CDW and, by extension, the PDW, observed in previous studies of UTe are likely confined to its surface.
