Parametric Resonance in Quantum Field Theory [PDF]
Physical Review Letters, 2003 We present the first study of parametric resonance in quantum field theory from a complete next-to-leading order calculation in a 1/N-expansion of the 2PI effective action, which includes scattering and memory effects. We present a complete numerical solution for an O(N)-symmetric scalar theory and provide an approximate analytic description of the ...

Parametric Symmetry Breaking in a Nonlinear Resonator [PDF]
Physical Review Letters, 2016 Much of the physical world around us can be described in terms of harmonic oscillators in thermodynamic equilibrium. At the same time, the far from equilibrium behavior of oscillators is important in many aspects of modern physics. Here, we investigate a resonating system subject to a fundamental interplay between intrinsic nonlinearities and a ...

Parametric Resonance in the Logistic Equation with Delay under a Two-Frequency Perturbation
Моделирование и анализ информационных систем, 2013 A logistic equation with a delay feedback circuit and with periodic perturbation of parameters is considered. The problem parameters (a coefficient of the linear growth and a delay) are chosen close to the critical values at which a cycle is bifurcated ...

Parametric resonance of axially functionally graded pipes conveying pulsating fluid
Applied Mathematics and MechanicsBased on the generalized Hamilton’s principle, the nonlinear governing equation of an axially functionally graded (AFG) pipe is established. The non-trivial equilibrium configuration is superposed by the modal functions of a simply supported beam.
