Quantum entanglement without superposition
Hans Christian Öttinger
Superposition states are at the origin of many paradoxes in quantum mechanics. By unraveling the von Neumann equation for density matrices, we develop a superposition-free formulat…
Fixed Point Quantum Monte Carlo
Romain Chessex, Massimo Borrelli, Hans Christian Öttinger
We present a new approach to the study of equilibrium properties in many-body quantum physics. Our method takes inspiration from Density Matrix Quantum Monte Carlo and incorporates…
Modular Dynamical Semigroups for Quantum Dissipative Systems
David Taj, Hans Christian Öttinger
We introduce a class of Markovian quantum master equations, able to describe the dissipative dynamics of a quantum system weakly coupled to one or several heat baths. The dissipati…
Stochastic process behind nonlinear thermodynamic quantum master equation
Hans Christian Öttinger
We propose a piecewise deterministic Markovian jump process in Hilbert space such that the covariance matrix of this stochastic process solves the thermodynamic quantum master equa…
The nonlinear thermodynamic quantum master equation
Hans Christian Öttinger
The quantum master equation obtained by generalizing the geometric formulation of nonequilibrium thermodynamics to dissipative quantum systems is seriously nonlinear. We argue that…
The geometry and thermodynamics of dissipative quantum systems
Hans Christian Öttinger
Dirac's method of classical analogy is employed to incorporate quantum degrees of freedom into modern nonequilibrium thermodynamics. The proposed formulation of dissipative quantum…
