Stability of the Pb divalent state in insulating and metallic PbCrO3

Jianfa Zhao, Shu-Chih Haw, Xiao Wang, Lipeng Cao, Hong-Ji Lin, Chien-Te Chen, Christoph J. Sahle, Arata Tanaka, Jin-Ming Chen, Changqing Jin, Zhiwei Hu, and Liu Hao Tjeng

Phys. Rev. B 107, 024107 (2023) - Published 26 January, 2023

PbCrO3 is a perovskite that undergoes a large volume collapse and concurrently an insulator-metal transition with pressure. While one may think that the volume collapse can be associated with conversion of Pb2+ ions to the smaller Pb4+, the spectroscopic measurements in this experiment reveal that the Pb ions remain divalent. Instead, the Cr ions undergo a transition from a charge-disproportionated 2Cr3+/Cr6+ configuration to a homogenous Cr4+ with pressure. Thus, the authors can explain the insulating/metallic nature of PbCrO3 at low/high pressures, respectively.

Migration of Ga vacancies and interstitials in βGa2O3

Ymir K. Frodason, Joel B. Varley, Klaus Magnus H. Johansen, Lasse Vines, and Chris G. Van de Walle

Phys. Rev. B 107, 024109 (2023) - Published 31 January, 2023

The authors present a systematic and comprehensive theoretical study of Ga vacancy and interstitial migration in monoclinic gallium sesquioxide, based on hybrid functional calculations and the nudged elastic band technique. Notably, it is shown that the Ga vacancy can form a favorable three-split configuration, consisting of three Ga vacancies and two Ga interstitials, which enables migration with a dramatically lower migration barrier than previously calculated, further demonstrating the important role of split vacancies in this material.

Ab initio study of metastable occupation of tetrahedral sites in palladium hydrides and its impact on superconductivity

Antonella Meninno and Ion Errea

Phys. Rev. B 107, 024504 (2023) - Published 11 January, 2023

Palladium hydride is one of the rare examples of superconducting hydrides at ambient pressure, exhibiting a critical temperature of 10 K in its equilibrium structure, with hydrogen atoms occupying octahedral interstitial sites of the palladium fcc lattice. Making use of ab initio calculations considering quantum anharmonic lattice effects, the authors show here that full or partial occupation of tetrahedral sites is possible in metastable structures, but that their superconducting critical temperature is lower than the equilibrium case with full octahedral occupation.

Critical magnetic fields and electron pairing in magic-angle twisted bilayer graphene

Wei Qin, Bo Zou, and Allan H. MacDonald

Phys. Rev. B 107, 024509 (2023) - Published 26 January, 2023

The microscopic mechanism of superconductivity in magic-angle twisted bilayer graphene (MATBG) is currently under active debate. The authors propose here that valuable constraints are implied by the band-filling dependences of the critical temperature and the critical magnetic field, which together define an average Fermi velocity. They show that a robust inverse correlation between the critical temperature and the average Fermi velocity holds in models with band-filling independent pairing interactions. The absence of such an association in experiments suggests that the pairing glue in MATBG is strongly band-filling dependent.

Pressure-induced metallization and superconductivity in the layered van der Waals semiconductor GaTe

Jin Jiang, Xuliang Chen (陈绪亮), Shuyang Wang, Chao An, Ying Zhou, Min Zhang, Yonghui Zhou, and Zhaorong Yang

Phys. Rev. B 107, 024512 (2023) - Published 31 January, 2023

Investigations show that the physical properties of the layered van der Waals semiconductor GaTe are strongly layer dependent. Here, the authors systematically study its properties by using external pressure as a tuning knob. They first find pressure-induced metallization and superconductivity simultaneously occurring at ~3 GPa, presumably owing to a quasi-two-dimensional to three-dimensional structural crossover and to an electronic phase transition due to a change of the bonding nature between layers from weak van der Waals interaction to strong Coulomb coupling. A second distinct superconducting phase is then observed at ~10 GPa due to a structural transition.

Characterizing random-singlet state in two-dimensional frustrated quantum magnets and implications for the double perovskite Sr2CuTe1xWxO6

Huan-Da Ren, Tian-Yu Xiong, Han-Qing Wu, D. N. Sheng, and Shou-Shu Gong

Phys. Rev. B 107, L020407 (2023) - Published 19 January, 2023

Understanding disorder-induced exotic states in two-dimensional magnets is one of the central topics in the study of frustrated magnetism. Here, the authors focus on the randomness-induced disordered phase in the spin-½ J1J2 square-lattice Heisenberg model with a strong bond randomness, by using large-scale density matrix renormalization group (DMRG) simulations. The results not only reveal the absent spin-glass order, but also identify the power-law decay of the average spin correlation and the exponential decay of the typical spin correlation. These all agree with the corresponding behavior in the one-dimensional random-singlet state and characterize the random-singlet nature of this disordered phase. This shows that DMRG simulations provide opportunities for exploring the disorder effect in two-dimensional magnets.

Andreev reflection spectroscopy in strongly paired superconductors

Cyprian Lewandowski, Étienne Lantagne-Hurtubise, Alex Thomson, Stevan Nadj-Perge, and Jason Alicea

Phys. Rev. B 107, L020502 (2023) - Published 6 January, 2023

One of the challenges in the pursuit of solid state BEC superconductors is the need for unambiguous experimental signatures. Here, the authors propose a new signature, relying on Andreev reflection, which distinguishes BEC from BCS superconductors. They demonstrate that, in a standard tunneling spectroscopy setup, a BEC superconductor exhibits suppressed Andreev reflection; however, if the tunneling barrier becomes a potential well, then appreciable Andreev reflection can be revived. Their predictions can be probed in various architectures that are also discussed.

Ab initio study of metastable occupation of tetrahedral sites in palladium hydrides and its impact on superconductivity

Antonella Meninno and Ion Errea

Phys. Rev. B 107, 024504 (2023) - Published 11 January, 2023

Palladium hydride is one of the rare examples of superconducting hydrides at ambient pressure, exhibiting a critical temperature of 10 K in its equilibrium structure, with hydrogen atoms occupying octahedral interstitial sites of the palladium fcc lattice. Making use of ab initio calculations considering quantum anharmonic lattice effects, the authors show here that full or partial occupation of tetrahedral sites is possible in metastable structures, but that their superconducting critical temperature is lower than the equilibrium case with full octahedral occupation.

The microscopic mechanism of superconductivity in magic-angle twisted bilayer graphene (MATBG) is currently under active debate. The authors propose here that valuable constraints are implied by the band-filling dependences of the critical temperature and the critical magnetic field, which together define an average Fermi velocity. They show that a robust inverse correlation between the critical temperature and the average Fermi velocity holds in models with band-filling independent pairing interactions. The absence of such an association in experiments suggests that the pairing glue in MATBG is strongly band-filling dependent.

Investigations show that the physical properties of the layered van der Waals semiconductor GaTe are strongly layer dependent. Here, the authors systematically study its properties by using external pressure as a tuning knob. They first find pressure-induced metallization and superconductivity simultaneously occurring at ~3 GPa, presumably owing to a quasi-two-dimensional to three-dimensional structural crossover and to an electronic phase transition due to a change of the bonding nature between layers from weak van der Waals interaction to strong Coulomb coupling. A second distinct superconducting phase is then observed at ~10 GPa due to a structural transition.
