Invariant measures of randomized quantum trajectories

Tristan Benoist, Sascha Lill, Cornelia Vogel

Quantum trajectories are Markov chains modeling quantum systems subjected to repeated indirect measurements. Their stationary regime depends on what observables are measured on the…

Grand-Canonical Typicality

Cedric Igelspacher, Roderich Tumulka, Cornelia Vogel

We study how the grand-canonical density matrix arises in macroscopic quantum systems. ``Canonical typicality'' is the known statement that for a typical wave function from a m…

Normal Typicality and Dynamical Typicality for a Random Block-Band Matrix Model

László Erdős, Joscha Henheik, Cornelia Vogel

We prove normal typicality and dynamical typicality for a (centered) random block-band matrix model with block-dependent variances. A key feature of our model is that we achieve in…

Long-Time Behavior of Typical Pure States from Thermal Equilibrium Ensembles

Cornelia Vogel

We consider an isolated macroscopic quantum system in a pure state evolving unitarily in a separable Hilbert space and take for granted that different macro sta…

Macroscopic Thermalization for Highly Degenerate Hamiltonians After Slight Perturbation

Barbara Roos, Shoki Sugimoto, Stefan Teufel +2

We say of an isolated macroscopic quantum system in a pure state that it is in macroscopic thermal equilibrium (MATE) if lies in or close to a suitable subspace $\mathcal{H…

Canonical Typicality For Other Ensembles Than Micro-Canonical

Stefan Teufel, Roderich Tumulka, Cornelia Vogel

We generalize Lévy's lemma, a concentration-of-measure result for the uniform probability distribution on high-dimensional spheres, to a much more general class of measures, so-cal…

Typical Macroscopic Long-Time Behavior for Random Hamiltonians

Stefan Teufel, Roderich Tumulka, Cornelia Vogel

We consider a closed macroscopic quantum system in a pure state evolving unitarily and take for granted that different macro states correspond to mutually orthogonal subspace…

Time Evolution of Typical Pure States from a Macroscopic Hilbert Subspace

Stefan Teufel, Roderich Tumulka, Cornelia Vogel

We consider a macroscopic quantum system with unitarily evolving pure state and take it for granted that different macro states correspond to mutually orthogon…
