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…
