DFT calculations of Raman intensities for (BEDT-TTF) dimer induces reconsideration of C=C stretching phonons assignment in -phase BEDT-TTF salts. A model for interdimer electron-molecular vibration coupling explains crossed-polarized Raman spectra, yielding an estimate of effective dimer Hubbard parameters. Calculations for a charge-ordered (CO) dimer show that Raman in the neglected ~1200 cm spectral region probes the CO pattern in systems undergoing a CO phase transition or fluctuating regime. In ferroelectric -(BEDT-TTF)Hg(SCN)Cl Raman suggests a (BEDT-TTF)(BEDT-TTF) pattern, which is opposite to the currently accepted intradimer CO.

The immense parameter complexity of current neural-network quantum states (NQS) in continuous space renders their application to realistic physical systems impossible. Here, the authors rigorously motivate a many-body coordinate transformation as basis for a variational neural-network Ansatz, implement it via message-passing neural networks, and show a resulting reduction of two orders of magnitude in parameter complexity and convergence speed. With this, the authors open the door for future NQS studies of extended systems in the thermodynamic limit.

Phys. Rev. B 110, 035118 (2024) - Published 8 July, 2024
The authors use many-body perturbation theory to predict how stacking, twisting, and interlayer distance affect intralayer and interlayer excitons in the transition metal dichalcogenide van der Waals heterostructures MoS₂/WS₂ and MoSe₂/WSe₂. They find “gray” excitons, visible only for in-plane detection. Their analysis into the excitonic lifetimes supports the idea of exciton transport for innovative applications in quantum information systems, next-generation electronic devices, photodetectors light-emitting devices, and lasers. Additionally, the authors observe that the misaligned heterostructure shows a unique state with two intralayer excitons degenerate in energy.

Phys. Rev. B 110, 035122 (2024) - Published 8 July, 2024
Bilayer graphene’s flat bands host momentum-polarized nematic phases stabilized by exchange interactions, where the carriers spontaneously populate one of several Fermi pockets induced by trigonal warping. Carriers sample -dependent band mass in the polarized momentum-distribution, making transport coefficients sensitive to pocket polarization, and resulting in the ohmic resistivity decreasing with temperature. Under strong electric field, the momentum-polarized states feature switching between different pockets. This behavior, along with negative , may serve as a diagnostic of pocket-polarized order.

In the context of fractional quantum anomalous Hall physics in twisted homobilayer transitional metal dichalcogenides, an emergent magnetic field picture, termed the adiabatic approximation, can be used to explain the emergence of ideal flat bands from the continuum model description. The authors justify here the adiabatic approximation in experimentally relevant parameter regimes and show that the adiabatic approximation is equivalent to an Aharonov-Casher type flat ideal band subject to a periodic potential. Although the potential can significantly modify some properties of the Aharonov-Casher band, its flatness and ideal quantum geometry will be maintained under certain conditions.

Kagome metals are exciting platforms to explore electronic instabilities such as charge density waves. The authors study here magnetotransport properties of various kagome compounds, with a focus on the charge density wave metal ScVSn and explain characteristic features among them. For example, ScVSn and CsVSb both have charge density waves, and both exhibit sublinear resistivity above the charge ordering temperature and anomalous Hall-like behavior below this temperature. This contrasts with LuVSn, which lacks charge ordering and lacks these intriguing transport hallmarks.

Mesoscopic quantum devices, such as quantum dots in a Coulomb blockade regime, are suitable platforms for emulating strongly correlated many-body effects. Considering a quantum dot with Kramers degenerate doublets of Majorana zero modes in time-reversal invariant triplet superconductors with strong charging energy effects and order parameter fluctuations, the authors suggest here a setup realizing a novel Kondo fixed point. Using Abelian bosonization, they show that the system displays Fermi-liquid and non-Fermi-liquid ground state characteristics alike.

The quantum geometric tensor (QGT) encodes information of the local geometry and topology of quantum states. While the QGT of pure quantum states is well known, its generalization to mixed quantum states requires a full characterization of the underlying geometric structure. Here, the authors derive the gauge-invariant QGT of mixed states based on the mathematically rigorous Uhlmann fiber bundle and highlight the similarities and differences of the local geometries of pure and mixed states.

This study is an experimental observation and characterization of the long-anticipated topological phase transition between different types of nodal electronic spectra in pyrochlore iridates. A unique combination of theory and measurements reveal that an incoherent part of the Raman scattering spectrum can unambiguously distinguish between Weyl and quadratic band-touching quasiparticles in correlated topological materials, while extracting Fermi energy relative to the node, Coulomb interaction effects and the amount of disorder. The results provide a critical verification of some prominent expectations that have been driving the research on pyrochlore iridates in recent years.
Extensive long-range entanglement at finite temperatures from a nonequilibrium bias

Phys. Rev. B 110, 035149 (2024) - Published 19 July, 2024
In a quantum many-body system, any two contiguous subsystems are typically either weakly entangled, or this entanglement decays with their separation. Could one observe strong long-range entanglement in a natural setup? Through exact calculations, the authors show here that such a remarkable behavior emerges in a simple 1D wire containing free fermions with a single scatterer, subject to temperature or voltage bias. The phenomenon arises from the coherent nature of the scattering, and may bear implications to more complex nonequilibrium systems.

Cavity confinement of quantum materials can induce a strong coupling between the electronic system and the quantum electromagnetic field, potentially leading to novel quantum phenomena of light and matter. The authors study here how the ultrastrong light-matter coupling can affect the Kondo effect. Nonperturbative analyses show that the ultrastrong coupling can enhance the Kondo temperature and give rise to several notable phenomena, including universal scalings of the cavity-modified Kondo effect, the photon occupation number, and the entanglement entropy between the cavity and electrons.
