Quantum algorithm for solving differential equations using SLAC derivatives
Rakshit M. Gharat, Gopikrishnan Muraleedharan, Dominic W. Berry +1
In numerical approaches to solving differential equations on a lattice, a representation of the derivative operator that correctly matches the continuum behaviour of functions of m…
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…
Circuit Complexity in an interacting quenched Quantum Field Theory
Sayantan Choudhury, Rakshit Mandish Gharat, Saptarshi Mandal +1
In this work, we explore the effects of a quantum quench on the circuit complexity for a quenched quantum field theory having weakly coupled quartic interaction. We use the invaria…
Entanglement in interacting quenched two-body coupled oscillator system
Sayantan Choudhury, Rakshit Mandish Gharat, Saptarshi Mandal +3
In this work, we explore the effects of a quantum quench on the entanglement measures of a two-body coupled oscillator system having quartic interaction. We use the invariant opera…
