Untangling entanglement and chaos
Meenu Kumari, Shohini Ghose
We present a method to calculate an upper bound on the generation of entanglement in any spin system using the Fannes-Audenaert inequality for the von Neumann entropy. Our method n…

Quantum-classical correspondence in the vicinity of periodic orbits
Meenu Kumari, Shohini Ghose
Quantum-classical correspondence in chaotic systems is a long-standing problem. We describe a method to quantify Bohr's correspondence principle and calculate the size of quantum n…

Stabilizing quantum dynamics through coupling to a quantized environment
Meenu Kumari, Eduardo Martin-Martinez, Achim Kempf +1
We show that introducing a small uncertainty in the parameters of quantum systems can make the dynamics of these systems robust against perturbations. Concretely, for the case wher…
