Criticality enabled long-range order in a U(1)-symmetric spin-1 Heisenberg chain with biquadratic interactions
Natalia Chepiga, Fabian H. L. Essler
In a recent paper Nahum argued on the basis of a renormalization-group analysis that, contrary to standard lore, ground states of 1D spin chains with short-range interactions can s…
Microscopically exact transport equation for the quantum Calogero model
Vir B. Bulchandani, Fabian H. L. Essler
We derive an exact transport equation for the quantum Calogero model, i.e. inverse-square interacting bosons on a line, from microscopic first principles.
Interacting hydrodynamic modes in spinless fermions with dephasing noise
Fabian H. L. Essler, Patrik Penc
We study the non-equilibrium dynamics of spinless fermions with dephasing noise in the framework of a many-particle Lindblad equation. Using a mapping to the exactly solvable one-d…
Quench Spectroscopy of Magnetic Excitations on a Superconducting Quantum Processor
D. A. Millar, G. W. Pennington, N. T. M. Siow +5
The elementary excitation spectrum of a many-body quantum system encodes many key properties, including phenomena as diverse as transport, thermalisation and ground state structure…
Non-equilibrium quantum dynamics of interacting integrable models by Monte Carlo sampling Lehmann representations
Riccardo Senese, Fabian H. L. Essler
Determining the dynamics of interacting integrable many-particle quantum systems at finite times after homogeneous quantum quenches is a long-standing challenge. We present a Monte…
Exact Quantum Many-Body Scars by a generalized Matrix-Product Ansatz
Sascha Gehrmann, Fabian H. L. Essler
We construct exact eigenstates of quantum many-body systems with Hamiltonians that are not frustration-free in matrix product form, based on a local error cancellation ansatz motiv…
