Coherence, Path-Predictability and I-Concurrence: A Triality
Abhinash Kumar Roy, Neha Pathania, Nitish Kumar Chandra +2
It is well known that fringe contrast is not a good quantifier of the wave nature of a quanton in multipath interference. A new interference visibility, based on the Hilbert-Schmid…
Dynamics of tripartite correlations for three qubits in independent thermal reservoirs
Sourabh Magare, Abhinash Kumar Roy, Prasanta K. Panigrahi
We investigate the dynamical evolution of multipartite entanglement in tripartite systems with three qubits present in independent thermal reservoirs, modelled as infinite set of q…
Trace dynamics, and a ground state in spontaneous quantum gravity
Abhinash Kumar Roy, Anmol Sahu, Tejinder P. Singh
We have recently proposed a Lagrangian in trace dynamics, to describe a possible unification of gravity, Yang-Mills fields, and fermions, at the Planck scale. This Lagrangian for t…
'Complementarity' in paraxial and non-paraxial optical beams
Abhinash Kumar Roy, Nitish Kumar Chandra, Soumik Mahanti +1
Establishing the correspondence of two dimensional paraxial and three dimensional non-paraxial optical beams with the qubit and qutrit systems respectively, we derive a complementa…
