Electronic-Structure Correlations Governing Superconductivity in Nb-Based High-Entropy Alloys
Md Sabbir Hossen Bijoy, Vladislav Korostelev, Deva Prasaad Neelakandan +10
Superconducting high-entropy alloys have recently emerged as a new platform for exploring superconductivity in highly disordered metallic systems and may offer advantages for appli…
Anomalous spin-lattice coupling in a 2D antiferromagnetic semiconductor revealed by surface acoustic Rayleigh waves
Zahra Ebrahim Nataj, Md. Sabbir Hossen Bijoy, Vladislav Korostelev +5
Magnetic order in van der Waals magnets can strongly influence their lattice dynamics, yet how this interaction manifests across different phonon length scales remains unclear. Opt…
Quantum Spin Singlet Ground State with Large Excitation Gap in the S = 3/2 quasi-1D van der Waals materials MoX3 (X = I, Br)
Jordan Teeter, Topojit Debnath, Harshil Goyal +18
We report the first experimental evidence for a quantum-disordered spin-singlet ground state and gapped triplon excitations in quasi-one-dimensional van der Waals materials. The in…
Acoustic Phonon Characteristics of Gallium Oxide Single Crystals Investigated with Brillouin-Mandelstam Light Scattering Spectroscopy
Dylan Wright, Erick Guzman, Md. Sabbir Hossen Bijoy +5
We report an investigation of the bulk and surface acoustic phonons in gallium oxide ultra-wide bandgap single crystals along various crystallographic directions using Brillouin-Ma…
