Kibble-Zurek mechanism and errors of gapped quantum phases
Amit Jamadagni, Javad Kazemi, Arpan Bhattacharyya
Kibble-Zurek mechanism relates the domain of non-equilibrium dynamics with the critical properties at equilibrium. It establishes a power law connection between non-equilibrium def…
Quantum state complexity meets many-body scars
Sourav Nandy, Bhaskar Mukherjee, Arpan Bhattacharyya +1
Scar eigenstates in a many-body system refers to a small subset of non-thermal finite energy density eigenstates embedded into an otherwise thermal spectrum. This novel non-thermal…
Bootstrapping the Kronig-Penney Model
Matthew J. Blacker, Arpan Bhattacharyya, Aritra Banerjee
Recently, bootstrap methods from conformal field theory have been adapted for studying the energy spectrum of various quantum mechanical systems. In this paper, we consider the app…
Thermodynamics of local baths in the context of work extraction
Tamal Guha, Mir Alimuddin, Amit Mukherjee +3
We consider locally thermal states (for two qubits) with certain amount of quantum entanglement present between them. Unlike previous protocols we show how work can be extracted by…
