Enhanced Pauli spin response, failure of Stoner \& spin fluctuation models, and presence of 6 plasmonic excitations in Ni metal
Shivani Bhardwaj, Antik Sihi, Sudhir K. Pandey
We revisit the electronic structure of Ni, using the density functional theory (DFT) and dynamical mean-field theory (DMFT) for the theoretical description of its electronic struct…
First-principles evidence of type-II Weyl phonons in rock-salt Tin Chalcogenides (SnS, SnSe & SnTe) materials
Antik Sihi, Sudhir K. Pandey
Recent studies on different topological materials in condensed matter physics have provided the evidence of topological nature for bosonic particle like phonons by performing vario…
Evidence of phase stability, topological phonon and temperature-induced topological phase transition in rocksalt SnS and SnSe
Antik Sihi, Sudhir K. Pandey
Both SnS and SnSe have been experimentally and theoretically confirmed as topological crystalline insulators in native rocksalt structure. Here, phononic structure, thermodynamical…
Exploring temperature dependent electron-electron interaction of topological crystalline insulators (SnS and SnSe) within Matsubara-time domain
Antik Sihi, Sudhir K. Pandey
Both experimental and theoretical studies show non-trivial topological behaviour in native rocksalt phase for SnS and SnSe and categorize these materials in topological crystalline…
