Anharmonic lattice dynamics and superconductivity in strained bulk and surface niobium
Mihir Ranjan Sahoo, Roman Lucrezi, Pedro Nunes Ferreira +5
Using first-principles calculations, we investigate how homogeneous strain and crystallographic surface orientation modify the vibrational and superconducting properties of niobium…

Vacancy-free cubic superconducting NbN enabled by quantum anharmonicity
Eva Kogler, Mihir R. Sahoo, Chia-Nien Tsai +10
Niobium nitride (NbN) is renowned for its exceptional mechanical, electronic, magnetic, and superconducting properties. The ideal 1:1 stoichiometric -NbN cubic phase, however,…

Entropic signature of resonant thermal transport: Ordered form of heat conduction
Albert Beardo, Prajit Rawte, Chia-Nien Tsai +1
Thermal transport in crystals is influenced by chemistry, boundaries, and nanostructure. The anharmonic phonon band structure extracted from molecular-dynamics simulations provides…
