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…

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…

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…
