Realizing high-temperature superconductivity in compressed molecular-hydrogen through Li doping
Ashok K. Verma, P. Modak
In this study, we explore lithium-doped stable molecular hydrogen structures by performing first-principles crystal structure searches across varying compositions in the Li-H syste…
Pressure induced electride phase formation in calcium: A key to its strange high-pressure behavior
P. Modak, Ashok K. Verma, Peter M. Oppeneer
Elemental calcium (Ca), a simple metal at ambient conditions, has attracted huge interest because of its unusual high-pressure behavior in structural, electrical, and melting prope…
Prediction of an unusual trigonal phase of superconducting LaH stable from 250 to 425 GPa pressure
Ashok K. Verma, P. Modak, Fabian Schrodi +2
Based on evolutionary crystal structure searches in combination with ab initio calculations, we predict an unusual structural phase of the superconducting LaH that is stable…
Phonon-mode specific contributions to room-temperature superconductivity in atomic hydrogen at high pressures
Ashok K. Verma, P. Modak, Fabian Schrodi +2
We investigate the role of specific phonon mode symmetries for the room temperature superconductivity in atomic hydrogen under large pressure. Using anisotropic Migdal-Eliashberg t…
Electronic topological transitions in NbX (X = Al, Ga, In, Ge and Sn) under compression investigated by first principles calculations
