Tracking Entanglement Transfer: Emergence of Thermodynamics from Quantum Information
Debraj Debata, Abhirup Mukherjee, Siddhartha Lal
We study entanglement transfer in a minimal model of two qubits that are coupled with one another through an antiferromagnetic Heisenberg exchange (), and where one of t…
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…
Kondo breakdown as an entanglement transition driven by continuous measurement
Debraj Debata, Abhirup Mukherjee, Siddhartha Lal
We study the breakdown of Kondo screening by a local magnetic field from the perspective of a measurement-driven entanglement transition in a monitored quantum system. Here, the Ko…
Ultrafast Dynamics of Spin-Orbit Entangled Excitons Coupled to Magnetic Ordering in van der Waals Antiferromagnet NiPS3
Sidhanta Sahu, Anupama Chauhan, Poulami Ghosh +7
Spin-orbit entangled excitons (SOEE) in two-dimensional (2D) antiferromagnets provide direct access to explore unconventional many body interactions in correlated electron systems.…
Mott Criticality as the Confinement Transition of a Pseudogap-Mott Metal
Abhirup Mukherjee, S. R. Hassan, Anamitra Mukherjee +3
The phenomenon of Mott insulation involves the localization of itinerant electrons due to strong local repulsion. Upon doping, a pseudogap (PG) phase emerges - marked by selective…
