Schwinger-Keldysh path integral formalism for a Quenched Quantum Inverted Oscillator

Sayantan Choudhury, Suman Dey, Rakshit Mandish Gharat +2

In this work, we study the time-dependent behaviour of quantum correlations of a system of an inverted oscillator governed by out-of-equilibrium dynamics using the well-known Schwi…
