Breakdown of Quantum Chaos in the Staggered-Field XXZ Chain: Confinement and Meson Formation
Julia Wildeboer, Marton Lajer, Robert M. Konik
Confinement of fractionalized excitations can strongly restructure many-body spectra. We investigate this phenomenon in the gapped spin- XXZ chain subject to a stagger…
High-temperature quantum coherence of spinons in a rare-earth spin chain
Lazar L. Kish, Andreas Weichselbaum, Daniel M. Pajerowski +6
Conventional wisdom dictates that quantum effects become unimportant at high temperatures. In magnets, when the thermal energy exceeds interactions between atomic magnetic moments,…
Witnessing Quantum Entanglement Using Resonant Inelastic X-ray Scattering
Tianhao Ren, Yao Shen, Marton Lajer +9
Although entanglement is both a central ingredient in our understanding of quantum many-body systems and an essential resource for quantum technologies, we only have a limited abil…
