Low temperature equilibrium correlation functions in dissipative quantum systems
We introduce a new theoretical approach to dissipative quantum systems. By means of a continuous sequence of infinitesimal unitary transformations, we decouple the small quantum system that one is interested in from its thermodynamically large environment. This yields a trivial final transformed Hamiltonian. Dissipation enters through the observation that generically observables “decay” complet...
متن کاملIterative path integral formulation of equilibrium correlation functions for quantum dissipative systems
We present an iterative path integral algorithm for computing multitime correlation functions of a quantum system coupled to a dissipative bath of harmonic oscillators. By splitting the Boltzmann operator into two parts and reordering the propagators in the expression for canonical correlation functions, we are able to transform the evolution time contour into a symmetric one so that a forward ...
متن کاملLow-temperature correlation functions via forward–backward quantum dynamics
We present an extension of forward–backward quantum dynamics suitable for evaluating finite-temperature time correlation functions for one-dimensional systems at low temperatures. The procedure relies on the cooling action of the Boltzmann operator, which produces a state similar to the lowest energy eigenstate with the given symmetry. As we have shown earlier, the quantum trajectories of near-...
متن کاملFlow equations for dissipative quantum systems under non-equilibrium conditions
Flow equations for dissipative quantum systems under non-equilibrium conditions This work investigates dissipative quantum systems by means of flow equations for Hamiltonians. We consider the time evolution of two models out of non-equilibrium initial states. As a first application the dis-sipative harmonic oscillator will be solved exactly. The insights gained will be used in the second and no...
متن کاملCorrelation Functions in Open Quantum-Classical Systems
Quantum time correlation functions are often the principal objects of interest in experimental investigations of the dynamics of quantum systems. For instance, transport properties, such as diffusion and reaction rate coefficients, can be obtained by integrating these functions. The evaluation of such correlation functions entails sampling from quantum equilibrium density operators and quantum ...
