Universal inverse electrocaloric effect in perovskites

Xingyue Ma, Mingxing Chen, Jun-Ming Liu, Di Wu, and Yurong Yang

Phys. Rev. B 107, 184105 (2023) - Published 10 May, 2023

The electrocaloric effect offers a promising alternative to traditional gas compressing refrigeration. Unlike the normal electrocaloric effect, the inverse electrocaloric effect is believed to be very rare. In this study, first-principles-based effective Hamiltonian methods are used and the inverse electrocaloric effect is found to be a universal phenomenon in oxide and halide perovskites over different structural phases. Such an unusual effect originates from the entropy change related to the oxygen/halogen octahedron.

Neural-network-backed effective harmonic potential study of the ambient pressure phases of hafnia

Sebastian Bichelmaier, Jesús Carrete, Ralf Wanzenböck, Florian Buchner, and Georg K. H. Madsen

Phys. Rev. B 107, 184111 (2023) - Published 17 May, 2023

Machine learning methods, and in particular neural-network force fields (NNFF), are bridging the gap between macroscopically relevant parameters and quantum mechanical simulations. This work describes an NNFF training strategy and uses it as the back end for an effective harmonic potential study of phase transitions in hafnia. While good agreement with experiment is found regarding the monoclinic-tetragonal transition, the commonly assumed transition to a Fm3¯m cubic phase is found to be unlikely for the stoichiometric material

Floquet-Bloch resonances in near-petahertz electroabsorption spectroscopy of SiO2

M. Volkov, S. A. Sato, A. Niedermayr, A. Rubio, L. Gallmann, and U. Keller

Phys. Rev. B 107, 184304 (2023) - Published 5 May, 2023

Complex nonadiabatic dynamics are observed when the quiver energy of an electron-hole pair in a strong laser field becomes comparable to the photon energy. Here, the authors extend quasistatic electromodulation spectroscopy based on the Franz-Keldysh effect to this regime and show that in this limit it is governed by resonant transitions between Floquet-Bloch states. This regime opens opportunities to probe the effective mass as well as the ponderomotive and binding energies of the electron-hole pair on the attosecond timescale.

Magnon dynamics in a skyrmion-textured domain wall of antiferromagnets

Seungho Lee, Kouki Nakata, Oleg Tchernyshyov, and Se Kwon Kim

Phys. Rev. B 107, 184432 (2023) - Published 16 May, 2023

The novel interaction of a skyrmion-textured domain wall and magnons is investigated theoretically for 2D antiferromagnets with the aid of supersymmetric quantum mechanics. The scattering of propagating magnons at the domain wall is found to be governed by the emergent magnetic field coming from the skyrmion texture of the domain wall, which gives rise to the tunable spin Nernst effect. The exact theoretical analysis also yields new nonreciprocal magnons, bound to the topologically textured domain wall.

Stochastic magnetic tunnel junction with easy-plane dominant anisotropy

Jonathan Z. Sun, Christopher Safranski, Philip Trouilloud, Christopher D'Emic, Pouya Hashemi, and Guohan Hu

Phys. Rev. B 107, 184433 (2023) - Published 17 May, 2023

Super-paramagnetic fluctuation of a nanomagnet, when confined by a strong easy-plane anisotropy, can yield GHz speed random signal. A magnetic tunnel junction converts such moment movement into conductance fluctuation, and is useful as an entropy source for modern computing circuits. Here, the authors experimentally explore the base-line behavior of easy-plane magnetic tunnel junctions in the super-paramagnetic limit, using a CMOS back-end integrated fabrication process, and introduce some measurement methodologies to identify factors in device materials and fabrication in need of future optimization.

Ultrafast frustration breaking and magnetophononic driving of singlet excitations in a quantum magnet

F. Giorgianni, B. Wehinger, S. Allenspach, N. Colonna, C. Vicario, P. Puphal, E. Pomjakushina, B. Normand, and Ch. Rüegg

Phys. Rev. B 107, 184440 (2023) - Published 25 May, 2023

Ultrafast laser probing has revolutionized the study of quantum materials. Quantum magnets realize some of the most complex and entangled many-body states in condensed matter. Here, the authors unify ultrafast physics and quantum magnetism by pump-probe experiments on the frustrated magnet SrCu2(BO3)2, using terahertz light pulses to create coherent driving of the lattice phonons, which in turn creates a special singlet spin excitation. Their phonon-based method introduces a universal mechanism for controlling nonequilibrium quantum many-body physics on ultrafast timescales.

Quantum pathways of carrier and coherent phonon excitation in bismuth

Azize Koç, Isabel Gonzalez-Vallejo, Matthias Runge, Ahmed Ghalgaoui, Klaus Reimann, Laurenz Kremeyer, Fabian Thiemann, Michael Horn-von Hoegen, Klaus Sokolowski-Tinten, Michael Woerner, and Thomas Elsaesser

Phys. Rev. B 107, L180303 (2023) - Published 23 May, 2023

Ultrafast mid-infrared excitation of an electron-hole plasma breaks the crystal symmetry of bismuth transiently and opens alternative quantum pathways for the excitation of coherent lattice motions. Probing the transient crystal structure directly by femtosecond x-ray diffraction reveals oscillations of diffracted intensity at a frequency of 2.6 THz, which persist on a picosecond time scale. They reflect coherent wave packet motions along back-folded phonon coordinates in the crystal of reduced symmetry. Optically induced symmetry breaking thus allows for modifying phonon excitations.

The novel interaction of a skyrmion-textured domain wall and magnons is investigated theoretically for 2D antiferromagnets with the aid of supersymmetric quantum mechanics. The scattering of propagating magnons at the domain wall is found to be governed by the emergent magnetic field coming from the skyrmion texture of the domain wall, which gives rise to the tunable spin Nernst effect. The exact theoretical analysis also yields new nonreciprocal magnons, bound to the topologically textured domain wall.

Stochastic magnetic tunnel junction with easy-plane dominant anisotropy

Super-paramagnetic fluctuation of a nanomagnet, when confined by a strong easy-plane anisotropy, can yield GHz speed random signal. A magnetic tunnel junction converts such moment movement into conductance fluctuation, and is useful as an entropy source for modern computing circuits. Here, the authors experimentally explore the base-line behavior of easy-plane magnetic tunnel junctions in the super-paramagnetic limit, using a CMOS back-end integrated fabrication process, and introduce some measurement methodologies to identify factors in device materials and fabrication in need of future optimization.

Ultrafast laser probing has revolutionized the study of quantum materials. Quantum magnets realize some of the most complex and entangled many-body states in condensed matter. Here, the authors unify ultrafast physics and quantum magnetism by pump-probe experiments on the frustrated magnet SrCu2(BO3)2, using terahertz light pulses to create coherent driving of the lattice phonons, which in turn creates a special singlet spin excitation. Their phonon-based method introduces a universal mechanism for controlling nonequilibrium quantum many-body physics on ultrafast timescales.
