Fractional Revival Dynamics in Kerr-Type Systems: Angular Momentum Moments and Classical Analogs
Ashish Kumar Patra, Saikumar Krithivasan
Wave packet revivals and fractional revivals are hallmark quantum interference phenomena that arise in systems with nonlinear energy spectra, and their signatures in expectation va…

Interplay of Quantum Coherence and Nonequilibrium Quantum Transport: An Exact Density Matrix Formulation in the Heisenberg Framework
Saikumar Krithivasan, Thingujam Yaiphalemba Meitei, Arijit Sen +1
We aim to bridge the gap between quantum coherence, quantum correlations, and nonequilibrium quantum transport in a quantum double-dot (QDD) system interacting with fermionic reser…

Quantumness of electron transport in quantum dot devices through Leggett-Garg inequalities: A non-equilibrium Green's function approach
Thingujam Yaiphalemba Meitei, Saikumar Krithivasan, Arijit Sen +1
Although coherent manipulation of electronic states can be achieved in quantum dot (QD) devices by harnessing nanofabrication tools, it is often hard to fathom the extent to which…
