Investigations on Quantum Correlations and Open Quantum System Dynamics Through Nuclear Spins
Arijit Chatterjee
Nuclear spins provide an ideal platform for studying quantum correlations and open quantum system dynamics across diverse areas, including quantum information, quantum foundations,…
Detection of Mpemba effect through good observables in open quantum systems
Pitambar Bagui, Arijit Chatterjee, Bijay Kumar Agarwalla
The Mpemba effect refers to the anomalous relaxation of a quantum state that, despite being initially farther from equilibrium, relaxes faster than a closer counterpart. Detecting…
Accelerated relaxation and Mpemba-like effect for operators in open quantum systems
Pitambar Bagui, Arijit Chatterjee, Bijay Kumar Agarwalla
Quantum Mpemba effect occurs when a quantum system, residing far away from the steady state, relaxes faster than a relatively nearer state. We look for the presence of this highly…
Direct Experimental Observation of Quantum Mpemba Effect without Bath Engineering
Arijit Chatterjee, Sakil Khan, Sachin Jain +1
The quantum Mpemba effect refers to the phenomenon of a quantum system in an initial state, far away from equilibrium, relaxing much faster than a state comparatively nearer to equ…
Enhanced non-macrorealism: Extreme violations of Leggett-Garg inequalities for a system evolving under superposition of unitaries
Arijit Chatterjee, H. S. Karthik, T. S. Mahesh +1
Quantum theory contravenes classical macrorealism by allowing a system to be in a superposition of two or more physically distinct states, producing physical consequences radically…
