Decoherence in regular systems
We consider unitary evolution of finite bipartite quantum systems and study time dependence of purity for initial cat states – coherent superpositions of Gaussian wave-packets. We derive explicit formula for purity in systems with nonzero time averaged coupling, a typical situation for systems where an uncoupled part of the Hamiltonian is Liouville integrable. Previous analytical studies have b...
متن کاملIntrinsic Decoherence in Mesoscopic Systems
We present measurements of the phase coherence time tf in six quasi-1D Au wires and clearly show that tf is temperature independent at low temperatures. We suggest that zero-point fluctuations of the phase coherent electrons are responsible for the observed saturation of tf. We introduce a new functional form for the temperature dependence and present the results of a calculation for the satura...
متن کاملDecoherence in Open Majorana Systems
Coupling to a thermal bath leads to decoherence of stored quantum information. For a system of Gaussian fermions, the fermionic analog of linear or Gaussian optics, these dynamics can be elegantly and efficiently described by evolution of the system’s covariance matrix. Taking both system and bath to be Gaussian fermionic, we observe that decoherence occurs at a rate that is independent of the ...
متن کاملDecoherence in quantum spin systems
Computer simulations of decoherence in quantum spin systems require the solution of the time-dependent Schrödinger equation for interacting quantum spin systems over extended periods of time. We use exact diagonalization, the Chebyshev polynomial technique, four Suzuki-formula algorithms, and the short-iterative-Lanczos method to solve a simple model for decoherence of a quantum spin system by ...
متن کاملLyapunov decoherence rate in classically chaotic systems.
We provide a path integral treatment of the decoherence process induced by a heat bath on a single particle whose dynamics is classically chaotic and show that the decoherence rate is given by the Lyapunov exponent. The loss of coherence is charaterized by the purity, which is calculated semiclassically within diagonal approximation, when the particle initial state is a single Gaussian wave pac...
