Circuit Complexity in Interacting Quenched Quantum Field Theory

In this work, we explore the effects of quantum quenching on circuit complexity quenched field theory with weakly coupled quartic interactions. We use invariant operator method under a perturbative framework to compute ground state system. give analytical expressions for specific reference and target states using Using particular cost functional, show computation interacting theory. Furthermore, numerical estimate respect quench rate, δt, two oscillators. The parametric variation in unambiguous contribution an arbitrary number oscillators has been studied dimensionless parameter (t/δt). comment different values coupling strength, numbers even dimensions.
