The passage of time and top-down causation
Barbara Drossel
It is often claimed that the fundamental laws of physics are deterministic and time-symmetric and that therefore our experience of the passage of time is an illusion. This paper wi…
Explicit expressions for stationary states of the Lindblad equation for a finite state space
Bernd Michael Fernengel, Barbara Drossel
The Lindblad equation describes the time evolution of a density matrix of a quantum mechanical system. Stationary solutions are obtained by time-averaging the solution, which will…
Dephasing versus collapse: Lessons from the tight-binding model with noise
Marco Hofmann, Barbara Drossel
Condensed matter physics at room temperature usually assumes that electrons in conductors can be described as spatially narrow wave packets - in contrast to what the Schrödinger eq…
What condensed matter physics and statistical physics teach us about the limits of unitary time evolution
Barbara Drossel
The Schrodinger equation for a macroscopic number of particles is linear in the wave function, deterministic, and invariant under time reversal. In contrast, the concepts used and…
Bifurcation and chaos in nonlinear Lindblad equations
Bernd Fernengel, Barbara Drossel
The Lindblad equation describes the dissipative time evolution of a density matrix that characterizes an open quantum system in contact with its environment. The widespread ensembl…
Contextual Wavefunction Collapse: An integrated theory of quantum measurement
Barbara Drossel, George Ellis
This paper is an in depth implementation of the proposal that the quantum measurement issue can be resolved by carefully looking at top-down contextual effects within realistic mea…
