Finite-Temperature Structural Optimization of the Bilayer Nickelate Superconductor LaNiO
Ryoma Asai, Ryotaro Arita, Takumi Chida +3
We develop a first-principles framework for finite-temperature structural optimization that incorporates vibrational contributions to the free energy through anharmonic phonon theo…
Entropy-assisted, long-period stacking of honeycomb layers in an AlB2-type silicide
Leonie Spitz, Takuya Nomoto, Shunsuke Kitou +8
Configurational entropy can impact crystallization processes, tipping the scales between structures of nearly equal internal energy. Using alloyed single crystals of Gd2PdSi3 in th…
Light-induced anomalous Hall conductivity in massive 3D Dirac semimetal CoSnS
Naotaka Yoshikawa, Shun Okumura, Yoshua Hirai +10
Weyl semimetals can emerge from Dirac semimetals when the time-reversal or spatial-inversion symmetries are broken. Recently, it has been proposed based on the Floquet theory that…
Bypassing the lattice BCS-BEC crossover in strongly correlated superconductors: resilient coherence from multiorbital physics
Niklas Witt, Yusuke Nomura, Sergey Brener +3
Superconductivity emerges from the spatial coherence of a macroscopic condensate of Cooper pairs. Increasingly strong binding and localization of electrons into these pairs comprom…
