Full Counting Statistics in the Transverse Field Ising Chain
Stefan Groha, Fabian H. L. Essler, Pasquale Calabrese
We consider the full probability distribution for the transverse magnetization of a finite subsystem in the transverse field Ising chain. We derive a determinant representation of…
Full counting statistics in the spin-1/2 Heisenberg XXZ chain
Mario Collura, Fabian H. L. Essler, Stefan Groha
The spin-1/2 Heisenberg chain exhibits a quantum critical regime characterized by quasi long-range magnetic order at zero temperature. We quantify the strength of quantum fluctuati…
Spinon decay in the spin-1/2 Heisenberg chain with weak next nearest neighbour exchange
Stefan Groha, Fabian H. L. Essler
Integrable models support elementary excitations with infinite lifetimes. In the spin-1/2 Heisenberg chain these are known as spinons. We consider the stability of spinons when a w…
Thermalization and light cones in a model with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We employ equation of motion techniques to study the non-equilibrium dynamics in a lattice model of weakly interacting spinless fermions. Our model provides a simple setting for an…
Prethermalization and thermalization in models with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We study the effects of integrability breaking perturbations on the non-equilibrium evolution of many-particle quantum systems. We focus on a class of spinless fermion models with…
