Ultrafast Critical Slowing of Spin Dynamics and Emergent Nonequilibrium Fano Interference in Fe3GeTe2
Anupama Chauhan, Sidhanta Sahu, Satyabrata Bera +5
FeGeTe is a prototypical metallic van der Waals ferromagnet with itinerant magnetism and a highly tunable Curie temperature, yet how electronic excitations couple to spin a…
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.…
Critical scaling behavior in skyrmion host ferromagnet CrTe1.38
Suman Kalyan Pradhan, Tuhin Debnath, Rui Wu
Materials hosting diverse topological spin textures hold significant potential for spintronic applications. In this context, CrTe1.38, a quasi-two-dimensional material, stands out…
Exceptionally Slow, Long Range, and Non-Gaussian Critical Fluctuations Dominate the Charge Density Wave Transition
Sk Kalimuddin, Sudipta Chatterjee, Arnab Bera +7
is a well-studied quasi-one-dimensional compound long-known to have a charge-density wave (CDW) transition around 263 K. We argue that the critical fluctuations of th…
