Preparation and detection of quasiparticles for quantum simulations of scattering
Mattia Morgavi, Peter Majcen, Marco Rigobello +2
We introduce a method for the selective preparation and detection of quasiparticle wave packets, based on creation operators that generate dressed, localized excitations on top of…

Towards D quantum electrodynamics on a cold-atom quantum simulator
Peter Majcen, Jesse J. Osborne, Philipp Hauke +3
Cold atoms have become a powerful platform for quantum-simulating lattice gauge theories in higher spatial dimensions. However, such realizations have been restricted to the lowest…

Optimal local basis truncation of lattice quantum many-body systems
Peter Majcen, Giovanni Cataldi, Pietro Silvi +1
We show how to optimally reduce the local Hilbert basis of lattice quantum many-body (QMB) Hamiltonians. The basis truncation exploits the most relevant eigenvalues of the estimate…
