Dynamical stability for finite quantum spin chains against a time-periodic inhomogeneous perturbation
We investigate dynamical stability of the ground state against a time-periodic and spatially-inhomogeneous magnetic field for finite quantum XXZ spin chains. We use the survival probability as a measure of stability and demonstrate that it decays as P (t) ∝ t under a certain condition. The dynamical properties should also be related to the level statistics of the XXZ spin chains with a constant...
متن کاملMerging and stability for time inhomogeneous finite Markov chains
As is apparent from most text books, the definition of a Markov process includes, in the most natural way, processes that are time inhomogeneous. Nevertheless, most modern references quickly restrict themselves to the time homogeneous case by assuming the existence of a time homogeneous transition function, a case for which there is a vast literature. The goal of this paper is to point out some...
متن کاملStability of Quantum Harmonic Oscillator under Time Quasi-periodic Perturbation
— We prove stability of the bound states for the quantum harmonic oscillator under non-resonant, time quasi-periodic perturbations by proving that the associated Floquet Hamiltonian has pure point spectrum. Résumé (Stabilité de l’oscillateur harmonique quantique sous les perturbations quasipériodiques) Nous démontrons la stabilité des états bornés de l’oscillateur harmonique sous les perturbati...
متن کاملMerging for time inhomogeneous finite Markov chains, Part I: singular values and stability
We develop singular value techniques in the context of time inhomogeneous finite Markov chains with the goal of obtaining quantitative results concerning the asymptotic behavior of such chains. We introduce the notion of c-stability which can be viewed as a generalization of the case when a time inhomogeneous chain admits an invariant measure. We describe a number of examples where these techni...
متن کاملQuantum theory of spin waves in finite chiral spin chains
We calculate the effect of spin waves on the properties of finite-size spin chains with a chiral spin ground state observed on biatomic Fe chains deposited on iridium(001). The system is described with a Heisenberg model supplemented with a Dzyaloshinskii-Moriya coupling and a uniaxial single ion anisotropy that presents a chiral spin ground state. Spin waves are studied using the Holstein-Prim...
