Nonlinear dynamical Casimir effect at weak nonstationarity

DA Trunin - The European Physical Journal C, 2022‏ - Springer
We show that even small nonlinearities significantly affect particle production in the
dynamical Casimir effect at large evolution times. To that end, we derive the effective …

Quantum vacuum, rotation, and nonlinear fields

A Flachi, M Edmonds - Physical Review D, 2023‏ - APS
In this paper, we extend previous results on the quantum vacuum or Casimir energy, for a
noninteracting rotating system and for an interacting nonrotating system, to the case where …

[HTML][HTML] Casimir effect in Snyder space

SA Franchino-Viñas, S Mignemi - Nuclear Physics B, 2020‏ - Elsevier
We show that two indistinguishable aspects of the divergences occurring in the Casimir
effect, namely the divergence of the energy of the higher modes and the non-compactness …

Quantum vacuum effects in nonrelativistic quantum field theory

M Edmonds, A Flachi, M Pasini - Physical Review D, 2023‏ - APS
Nonlinearities in the dispersion relations associated with different interactions designs,
boundary conditions, and the existence of a physical cutoff scale can alter the quantum …

Remarks on the large- model

A Flachi - Physical Review D, 2020‏ - APS
In this paper we consider the CPN-1 model confined to an interval of finite size at finite
temperature and chemical potential. We obtain, in the large-N approximation, a mixed …

Quantum vacuum phenomena in various backgrounds

A Flachi - International Journal of Modern Physics A, 2022‏ - World Scientific
In this paper, we will review, through various examples, some ideas connecting the physics
of the quantum vacuum and the Casimir effect with the mechanism of symmetry breaking in …
