Particle creation in nonstationary large N quantum mechanics
Dmitrii A. Trunin
We consider an analog of particle production in a quartic quantum oscillator with time-dependent frequency, which is a toy model of particle production in the dynamical Casi…
Dynamical Casimir effect in nonlinear vibrating cavities
Lianna A. Akopyan, Dmitrii A. Trunin
Nonlinear terms in the equations of motion can induce secularly growing loop corrections to correlation functions. Recently such corrections were shown to affect the particle produ…
On quantization in background scalar fields
E. T. Akhmedov, E. N. Lanina, D. A. Trunin
We consider (0+1) and (1+1) dimensional Yukawa theory in various scalar field backgrounds, which are solving classical equations of motion: or ,…
Comments on the adiabatic theorem
Dmitrii A. Trunin
We consider the simplest example of a nonstationary quantum system which is quantum mechanical oscillator with varying frequency and self-interaction. We calculate loop corr…
