Stochastic bra-ket interpretation of quantum mechanics
Hans Christian Öttinger
The stochastic nature of quantum mechanics is more naturally reflected in a bilinear two-process representation of density matrices rather than in squared wave functions. This prop…
Dynamical Triplet Unravelling: A quantum Monte Carlo algorithm for reversible dynamics
Romain Chessex, Massimo Borrelli, Hans Christian Öttinger
We introduce a quantum Monte Carlo method to simulate the reversible dynamics of correlated many-body systems. Our method is based on the Laplace transform of the time-evolution op…
Biexponential decay and ultralong coherence of a single qubit
Jérôme Flakowski, Maksym Osmanov, David Taj +1
A quantum two-state system, weakly coupled to a heat bath, is traditionally studied in the Born-Markov regime under the secular approximation with completely positive linear master…
Numerics for Hyperbolic Conservation Laws with Help from the Physical Entropy
Carl Philipp Zinner, Hans Christian Öttinger
Stable numerical simulations for a hyperbolic system of conservation laws of relaxation type but not in divergence form are obtained by incorporating the physical entropy into the…
Nonlinear thermodynamic quantum master equation: Properties and examples
Hans Christian Öttinger
The quantum master equation obtained from two different thermodynamic arguments is seriously nonlinear. We argue that, for quantum systems, nonlinearity occurs naturally in the ste…
