Current gate-based quantum computers have the potential to provide a computational
advantage if algorithms use quantum hardware efficiently. To make combinatorial …

We introduce two kinds of quantum algorithm to explore microcanonical and canonical
properties of many-body systems. The first is a hybrid quantum algorithm that, given an …

Systems of interacting bosons in triple-well potentials are of significant theoretical and
experimental interest. They are explored in contexts that range from quantum phase …

We investigate quantum-inspired algorithms to compute physical observables of quantum
many-body systems at finite energies. They are based on the quantum algorithms proposed …

Energy filter methods in combination with quantum simulation can efficiently access the
properties of quantum many-body systems at finite energy densities [S. Lu, PRX Quantum 2 …

We investigate how the temperature calculated from the microcanonical entropy compares
with the canonical temperature for finite isolated quantum systems. We concentrate on …

Accurate calculations of the spectral density in a strongly correlated quantum many-body
system are of fundamental importance to study its dynamics in the linear response regime …

Temperature is a deceptively simple concept that still raises deep questions at the forefront
of quantum physics research. The observation of thermalization in completely isolated …

We identify quantum many-body scars in the transverse field quantum Ising model on a
ladder. We make explicit how the corresponding (mid spectrum, low entanglement) many …

We numerically investigate the minimum number of interacting particles, which is required
for the onset of strong chaos in quantum systems on a one-dimensional lattice with short …
