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…

Signatures of emergent surface states across a displacive topological phase transition in BiI
Deep Singha Roy, Sk Kalimuddin, Subrata Pachhal +13
Topological phase transitions involving crystalline symmetry breaking provide a fertile ground to explore the interplay between symmetry, topology, and emergent quantum phenomena.…

Direction-Dependent Conduction Polarity in Altermagnetic CrSb
Banik Rai, Krishnendu Patra, Satyabrata Bera +5
CrSb has recently gained immense attention as an altermagnetic candidate. This work reports on the experimental observation of direction-dependent conduction polarity (DDCP) in alt…
