Quantum Correlations in the Decay of meson and Entanglement Entropy
Divya Sharma, Vaibhav Rawoot, Sudip Kumar Haldar
We present a phenomenological study of quantum correlations in the decay of mesons into a system of two vector mesons. The decay of the meson into two vector mesons con…
Interplay of asymmetry and fragmentation in the many-body tunneling dynamics of two-dimensional bosonic Josephson junctions
Anal Bhowmik, Rhombik Roy, Sudip Kumar Haldar
It is well known that the many-body tunneling of a bosonic condensate leads to (longitudinal) fragmentation along the tunneling direction. In this work, we prepare the initial grou…
Predicting topological quantum phase transition from dynamics via multisite entanglement
Leela Ganesh Chandra Lakkaraju, Sudip Kumar Haldar, Aditi Sen De
An exactly solvable Kitaev model in a two-dimensional square lattice exhibits a topological quantum phase transition which is different from the symmetry-breaking transition at zer…
Many-body effects in a composite bosonic Josephson junction
Sudip Kumar Haldar, Anal Bhowmik
In standard bosonic Josephson junctions (BJJs), particles tunnel between two single-well potentials linked by a finite barrier. The dynamics of standard BJJs have been extensively…
