Broken weak and strong spin rotational symmetries and tunable interaction between phonon and the continuum in Cr2Ge2Te6
Atul G. Chakkar, Deepu Kumar, Pradeep Kumar
Phase transitions with lowering temperature is a manifestation of decreased entropy and within the Landau theoretical framework these are accompanied by the symmetry breaking. When…

Interplay of topology and antiferromagnetic order in two-dimensional van der Waals crystals of (NixFe1-x)2P2S6
N. Khan, D. Kumar, V. Kumar +6
Mermin-Wagner theorem forbid spontaneous symmetry breaking of spins in one/two-dimensional systems at finite temperature and rules out the stabilization of this ordered state. Howe…

Tunable Resonance and Electron-Phonon Coupling in Layered MoS2
Deepu Kumar, Nasaru Khan, Rahul Kumar +2
Resonance Raman scattering, a very effective and sensitive technique for atomically thin semiconducting transition metal dichalcogenide, can be used to observe the phonons from the…
