Quench dynamics and zero-energy modes: the case of the Creutz model
R. Jafari, Henrik Johannesson, A. Langari +1
In most lattice models, the closing of a band gap typically occurs at high-symmetry points in the Brillouin zone. Differently, in the Creutz model describing a system of spinle…
Measurement quench in many-body systems
Abolfazl Bayat, Bedoor Alkurtass, Pasquale Sodano +2
Measurement is one of the key concepts which discriminates classical and quantum physics. Unlike classical systems, a measurement on a quantum system typically alters it drasticall…
Single-Site Entanglement of Fermions at a Quantum Phase Transition
Daniel Larsson, Henrik Johannesson
We show that the single-site entanglement of a generic spin-1/2 fermionic lattice system can be used as a reliable marker of a finite-order quantum phase transition, given certain…
