Author(s): M. Laura Urquiza, Matteo Gatti, and Francesco SottileWe present an ab initio study of neutral core and valence electronic excitations in α−Al2O3 by solving the Bethe-Salpeter equation (BSE) of many-body perturbation theory within an all-electron framework. Calculated spectra at the Al K and L1 edges are in remarkable agreement with available...
Author(s): Monalisa Chatterjee, Manoranjan Kumar, and Zoltán G. SoosThe frustrated ladder with alternate ferromagnetic exchange −JF and antiferromagnetic exchange JA to first neighbors and ferromagnetic exchange −JL to second neighbors is studied by exact diagonalization and density matrix renormalization group calculations in systems of 2N spins-12...

Author(s): Pavel A. Volkov, Étienne Lantagne-Hurtubise, Tarun Tummuru, Stephan Plugge, J. H. Pixley, and Marcel FranzRecent Josephson tunneling experiments on twisted flakes of high-Tc cuprate superconductor Bi2Sr2CaCu2O8+x revealed a nonreciprocal behavior of the critical interlayer Josephson current, i.e., a Josephson diode effect. Motivated by these...
Author(s): Alessio ZacconeThe dielectric properties of thin films are of paramount importance in a variety of technological applications, and of fundamental importance for solid-state research. In spite of this, there is currently no theoretical understanding of the dependence of the dielectric permittivity on the thickness … [Phys. Rev. B 109, 115435]...
Author(s): Robin Fréville, Agnès Dewaele, Nicolas Guignot, Philippe Faure, Laura Henry, Gaston Garbarino, and Mohamed MezouarThe high-pressure–high-temperature behavior of tin has been measured with x-ray diffraction and laser-heated diamond anvil cells up to 225 GPa at 300 K and to 110 GPa and ∼4000 K. Temperature has been measured using conventional...
