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…
