Phase Transition in the periodically pulsed Dicke Model
Sayak Dasgupta, Utso Bhattacharya, Amit Dutta
We study the effect of pulsed driving and kicked driving of the interaction term on the non-equilibrium phase transition in the Dicke Model. Within the framework of Floquet theory,…
A simple experiment demonstrating the connection between chaos and music
Nitica Sakharwade, Sayak Dasgupta
In this pedagogical paper we study the dripping pattern of a leaking faucet which we analyse on the basis of a musical procedure which we outline and match the power spectral densi…
Exploring chaos in Dicke Model using ground state fidelity and Loschmidt echo
Utso Bhattacharya, Sayak Dasgupta, Amit Dutta
We study the quantum critical behaviour of the Dicke Hamiltonian, with finite number of atoms and explore the signature of quantum chaos using measures like the ground state fideli…
