Emergence of a hidden-order phase well below the charge density wave transition in a topological Weyl semimetal (TaSe)I
Sk Kalimuddin, Sudipta Chatterjee, Arnab Bera +7
The emergence of a charge density wave (CDW) in a Weyl semimetal -- a correlated topological phase, is exceptionally rare in condensed matter systems. In this context, the quasi-on…

Revisiting MnSe : a Magnetic Semiconductor with Spin-Phonon coupling
Suman Kalyan Pradhan, Arnab Bera, Soham Das +3
Spin-phonon interactions in 2D magnetic materials are crucial in advancing next-generation spintronic devices. Therefore, identifying new materials with significant spin-phonon int…
