HIGHLIGHTED ARTICLES

Local structure, bonding, and asymmetry of ((NH2)2CH)PbBr3, CsPbBr3, and (CH3NH3)PbBr3

F. Bridges, J. Gruzdas, C. MacKeen, K. Mayford, N. J. Weadock, V. Urena Baltazar, Y. Rakita, Louis Waquier, Julian A. Vigil, Hemamala I. Karunadasa, and M. F. Toney

Phys. Rev. B 108, 214102 (2023) - Published 11 December, 2023

The local structure of hybrid organic-inorganic halide perovskites is of considerable interest due to the impact on optoelectronic and ion-conducting properties. Here, it is shown that the lead bromide perovskites are nearly perfect at low temperature, with negligible static disorder, through a temperature-dependent x-ray absorption spectroscopy study. As the crystal heats up, two things happen: the organic molecular-ion motion changes the Pb-Br bond strength at the orthorhombic-tetragonal transition, and anharmonicity (C3) contributes to a significant thermal disorder at room temperature.

Decodable hybrid dynamics of open quantum systems with Z2 symmetry

Yaodong Li and Matthew P. A. Fisher

Phys. Rev. B 108, 214302 (2023) - Published 4 December, 2023

Within a toy model of open quantum systems, this work discusses the relation between measurement-induced phase transitions (MIPTs) of quantum entanglement and quantum error correction (QEC), which also has a phase transition at an “error threshold”. In particular, the authors show how concepts from QEC can facilitate the observation of MIPTs and, conversely, how insights from MIPTs can inform the design of decoding algorithms.

Impact of hyperfine contributions on the ground state of spin-ice compounds

J. Gronemann, S. Chattopadhyay, T. Gottschall, E. Osmic, A. T. M. N. Islam, V. K. Anand, B. Lake, H. Kaneko, H. Suzuki, J. Wosnitza, and T. Herrmannsdörfer

Phys. Rev. B 108, 214412 (2023) - Published 14 December, 2023

Here, the authors determine thermodynamic properties of pyrochlore spin-ice compounds at subkelvin temperatures. In particular, the magnetic field dependence of the heat capacity and magnetic entropy of Ho2Ti2O7 and Pr2Hf2O7 shows the existence of additional states beyond the electronic spin and orbital degrees of freedom. One can understand the data through the presence of hyperfine states and complex hyperfine-coupled term schemes.

Field theory of a superconductor with repulsion

Amir Dalal, Jonathan Ruhman, and Vladyslav Kozii

Phys. Rev. B 108, 214521 (2023) - Published 26 December, 2023

Superconductivity, the state of zero resistance in metals, involves electrons forming a quantum liquid of pairs. However, here lies a conundrum; electrons repel each other due to the electric force, so why should they bind? The answer to this question was provided a long time ago by Pierre Morel and Phillip Anderson. However, to date, there is no existing generalization of Morel-Anderson theory that gives a comprehensive understanding of the properties of real superconductors. This paper bridges the gap by outlining a path to generalize their theory into a “quantum field theory”. Surprisingly, this theory is controlled by a unique point in configuration space (“saddle point”). Utilizing mathematical techniques, the authors can exploit this saddle point to reveal insights into superconductor properties, such as the break point in a magnetic field.

Possible explanation for the high superconducting Tc in bcc Ti at high pressure

Antonio Sanna, Camilla Pellegrini, Simone di Cataldo, Gianni Profeta, and Lilia Boeri

Phys. Rev. B 108, 214523 (2023) - Published 28 December, 2023

By means of ab initio calculations, the authors show here that neither a conventional nor an unconventional pairing mechanism can justify the observed 26-K superconducting Tc in compressed bcc titanium. They reconcile experimental and theoretical results by assuming the presence of Ti vacancies. These induce a phonon softening that increases the electron-phonon coupling at high pressure, yielding an agreement with measurements over the full pressure range 150–300 GPa. The proposed mechanism applies to multiple types of defects and can occur in several simple metals.

By means of ab initio calculations, the authors show here that neither a conventional nor an unconventional pairing mechanism can justify the observed 26-K superconducting Tc in compressed bcc titanium. They reconcile experimental and theoretical results by assuming the presence of Ti vacancies. These induce a phonon softening that increases the electron-phonon coupling at high pressure, yielding an agreement with measurements over the full pressure range 150–300 GPa. The proposed mechanism applies to multiple types of defects and can occur in several simple metals.
