Quantum Advantage of Thermal Machines with Bose and Fermi Gases
Saikat Sur, Arnab Ghosh
In this article, we show that a quantum gas, a collection of massive, non-interacting, indistinguishable quantum particles can be realized as a thermodynamic machine as an artifact…
Information scrambling and redistribution of quantum correlations through dynamical evolution in spin chains
Saikat Sur, V. Subrahmanyam
We investigate the propagation of local bipartite quantum correlations, along with the tripartite mutual information to characterize the information scrambling through dynamical ev…
Quantum counterpart of Measure synchronization: A study on a pair of Harper systems
Saikat Sur, Anupam Ghosh
Measure synchronization is a well-known phenomenon in coupled classical Hamiltonian systems over last two decades. In this paper, synchronization for coupled Harper system is inves…
Loschmidt echo of local dynamical processes in integrable and non integrable spin chains
Saikat Sur, V. Subrahmanyam
The Loschmidt echo is investigated to track the effect of the local QDP. It is also quite sensitive to whether the background dynamics is integrable or not. For the integrable case…
Interference of the signal from a local dynamical process with the quantum state propagation in spin chains
Saikat Sur, V. Subrahmanyam
The effect of a local instantaneous quantum dynamical process (QDP), either unitary or non-unitary, on the quantum state transfer through a unitary Hamiltonian evolution is investi…
Remotely detecting the signal of a local decohering process in spin chains
Saikat Sur, V. Subrahmanyam
We study the dynamics of a one dimensional quantum spin chain evolving from unentangled or entangled initial state. At a given instant of time a quantum dynamical process (ex. meas…
