Non-equilibrium quantum transport is crucial to technological advances ranging from
nanoelectronics to thermal management. In essence, it deals with the coherent transfer of …

Quantum computing is an exciting field that uses quantum principles, such as quantum
superposition and entanglement, to tackle complex computational problems …

Mechanisms for suppressing thermalization in disorder-free many-body systems, such as
Hilbert space fragmentation and quantum many-body scars, have recently attracted much …

Interactions of isolated quantum many-body systems typically scramble local information into
the entire system and make it unrecoverable. Ergodicity-breaking systems possess the …

Confinement is a prominent phenomenon in condensed matter and high-energy physics that
has recently become the focus of quantum-simulation experiments of lattice gauge theories …

This thesis develops advanced Tensor Network (TN) methods to address Hamiltonian
Lattice Gauge Theories (LGTs), overcoming limitations in real-time dynamics and finite …

We investigate the influence of external fields on the stability of spin helix states in an XXZ
Heisenberg model. Exact diagonalization on a finite system shows that random transverse …

Most isolated, many-body, quantum systems satisfy the eigenstate thermalization
hypothesis. However, several phenomena violate the hypothesis: many-body localization …
