Hamiltonian Learning in Quantum Field Theories
Robert Ott, Torsten V. Zache, Maximilian Prüfer +5
We discuss Hamiltonian learning in quantum field theories as a protocol for systematically extracting the operator content and coupling constants of effective field theory Hamilton…
Quantum phases of Rydberg atoms on a kagome lattice
Rhine Samajdar, Wen Wei Ho, Hannes Pichler +2
We analyze the zero-temperature phases of an array of neutral atoms on the kagome lattice, interacting via laser excitation to atomic Rydberg states. Density-matrix renormalization…
Nano-Scale `Dark State' Optical Potentials for Cold Atoms
M. Łącki, M. Baranov, H. Pichler +1
We discuss generation of subwavelength optical barriers on the scale of tens of nanometers, as conservative optical potentials for cold atoms. These arise from non-adiabatic correc…
Heating dynamics of bosonic atoms in a noisy optical lattice
Hannes Pichler, Johannes Schachenmayer, Andrew J. Daley +1
We analyze the heating of interacting bosonic atoms in an optical lattice due to intensity fluctuations of the lasers forming the lattice. We focus in particular on fluctuations at…
