Dynamical protection of quantum steering and fidelity dynamics in double Jaynes-Cummings model
Koushik Mandal, Chitra Rangan, Shohini Ghose
We investigate the dynamics of Einstein-Podolsky-Rosen (EPR) steering in a double Jaynes-Cummings model, where two initially entangled spatially separated two-level atoms in two ca…
Quantum recurrences and the arithmetic of Floquet dynamics
Amit Anand, Dinesh Valluri, Jack Davis +1
The Poincaré recurrence theorem shows that conservative systems in a bounded region of phase space eventually return arbitrarily close to their initial state after a finite amount…
Superposed quantum evolutions across chaotic and regular regimes
Amit Anand, Anne-Catherine de la Hamette, Robert Mann +1
While the superposition of quantum evolutions is known to produce interference effects, the interference between evolutions with regular and chaotic classical limits remains largel…
Canadian Physics Counts: An exploration of the diverse identities of physics students and professionals in Canada
Eden J. Hennessey, Anastasia Smolina, Skye Hennessey +4
The lack of diversity in physics remains a persistent worldwide problem. Despite being a quantitative discipline which relies on measurements to construct and validate hypotheses,…
Multipartite entanglement vs nonlocality for two families of -qubit states
Sanchit Srivastava, Shohini Ghose
Entangled states of multiple qubits can violate Bell-type inequalities indicating nonlocal behavior of multiqubit quantum correlations. We analyze the relation between multipartite…
Contextuality and Chaos
Sanchit Srivastava, Shohini Ghose
Classical chaos is marked by an extreme sensitivity to initial conditions, where infinitesimally close trajectories separate exponentially over time. In quantum mechanics, however,…
