Complexity of a quasiperiodically driven spin system
A quasiperiodically forced purely quantum spin2 system can exhibit rather irregular behaviour with a continuous power spectrum. We have shown analytically and numerically, that in these regimes both the topological entropy of a corresponding symbolic sequence and the maximal Lyapunov exponent vanish.
متن کاملKeldysh field theory for driven open quantum systems.
Recent experimental developments in diverse areas-ranging from cold atomic gases to light-driven semiconductors to microcavity arrays-move systems into the focus which are located on the interface of quantum optics, many-body physics and statistical mechanics. They share in common that coherent and driven-dissipative quantum dynamics occur on an equal footing, creating genuine non-equilibrium s...
متن کاملAsymptotic distributions of periodically driven stochastic systems.
We study the large-time behavior of Brownian particles moving through a viscous medium in a confined potential, and which are further subjected to position-dependent driving forces that are periodic in time. We focus on the case where these driving forces are rapidly oscillating with an amplitude that is not necessarily small. We develop a perturbative method for the high-frequency regime to fi...
متن کاملAsymptotic Heat Kernels in Quantum Field Theory
Asymptotic expansions were first introduced by Henri Poincaré in 1886. This paper describes their application to the semi-classical evaluation of amplitudes in quantum field theory with boundaries. By using zeta-function regularization, the conformal anomaly for a massless spin-12 field in flat Euclidean backgrounds with boundary is obtained on imposing locally supersymmetric boundary condition...
متن کاملAsymptotic Hodge theory and quantum products
Assuming suitable convergence properties for the Gromov-Witten potential of a Calabi-Yau manifold X, one may construct a polarized variation of Hodge structure over the complexified Kähler cone of X. In this paper we show that, in the case of fourfolds, there is a correspondence between “quantum potentials” and polarized variations of Hodge structures that degenerate to a maximally unipotent bo...
