Weak Coupling and Continuous Limits for Repeated Quantum Interactions
We consider a quantum system in contact with a heat bath consisting in an infinite chain of identical sub-systems at thermal equilibrium at inverse temperature β. The time evolution is discrete and such that over each time step of duration τ , the reference system is coupled to one new element of the chain only, by means of an interaction of strength λ. We consider three asymptotic regimes of t...
متن کاملFrom repeated to continuous quantum interactions
We consider the general physical situation of a quantum system H0 interacting with a chain of exterior systems ⊗IN∗H, one after the other, during a small interval of time h and following some Hamiltonian H on H0 ⊗H. We discuss the passage to the limit to continuous interactions (h → 0) in a setup which allows to compute the limit of this Hamiltonian evolution in a single state space: a continuo...
متن کاملRepeated and continuous interactions in open quantum systems
We consider a finite quantum system S coupled to two environments of different nature. One is a heat reservoir R (continuous interaction) and the other one is a chain C of independent quantum systems E (repeated interaction). The interactions of S with R and C lead to two simultaneous dynamical processes. We show that for generic such systems, any initial state approaches an asymptotic state in...
متن کاملWeak limits for quantum random walks.
We formulate and prove a general weak limit theorem for quantum random walks in one and more dimensions. With X(n) denoting position at time n, we show that X(n)/n converges weakly as n--> infinity to a certain distribution which is absolutely continuous and of bounded support. The proof is rigorous and makes use of Fourier transform methods. This approach simplifies and extends certain precedi...
متن کاملRepeated Quantum Interactions and Unitary Random Walks
Among the discrete evolution equations describing a quantum system HS undergoing repeated quantum interactions with a chain of exterior systems, we study and characterize those which are directed by classical random variables in RN . The characterization we obtain is entirely algebraical in terms of the unitary operator driving the elementary interaction. We show that the solutions of these equ...
