Stochastic resetting in discrete-time quantum dynamics: steady states and correlations in few-qubit systems Open
Time evolution in several classes of quantum devices is generated through the application of quantum gates. Resetting is a critical technological feature in these systems allowing for mid-circuit measurement and complete or partial qubit r…

Coined quantum walks on the line: Disorder, entanglement, and localization Open
Disorder in coined quantum walks generally leads to localization. We investigate the influence of the localization on the entanglement properties of coined quantum walks. Specifically, we consider quantum walks on the line and explore the …

Entanglement gap in 1D long-range quantum spherical models Open
We investigate the finite-size scaling of the entanglement gap in the one-dimensional long-range quantum spherical model (QSM). We focus on the weak long-range QSM, for which the thermodynamic limit is well-defined. This model exhibits a c…

Entanglement in the Quantum Spherical Model -- a Review Open
We review some recent results on entanglement in the Quantum Spherical Model (QSM). The focus lays on the physical results rather than the mathematical details. Specifically, we study several entanglement-related quantities, such asentangl…

Entanglement dynamics of a hard-core quantum gas during a Joule expansion Open
We study the entanglement dynamics of a one-dimensional hard-core quantum gas initially confined in a box of size L with saturated density ρ = 1. The gas is suddenly released into a region of size 2 L by moving one of the box edges. We sho…
