Long-lived non-thermal states in pumped one-dimensional systems of hard-core bosons
Patrycja Łydżba, Janez Bonča
We study a unitary time evolution of a symmetry-broken state in a form of a charge density wave in a finite system of interacting hard-core bosons, which can be mapped onto the XXZ…
Ergodicity Breaking Transition in Finite Disordered Spin Chains
Jan Šuntajs, Janez Bonča, Tomaž Prosen +1
We study disorder-induced ergodicity breaking transition in high-energy eigenstates of interacting spin-1/2 chains. Using exact diagonalization we introduce a cost function approac…
Photoinduced in-gap excitations in the one-dimensional extended Hubbard model
Hantao Lu, Can Shao, Janez Bonča +2
We investigate the time evolution of optical conductivity in the half-filled one-dimensional extended Hubbard model driven by a transient laser pulse, by using the time-dependent L…
Ferromagnetism in the Strong Hybridization Regime of the Periodic Anderson Model
C. D. Batista, J. Bonča, J. E. Gubernatis
We determine exactly the ground state of the one-dimensional periodic Anderson model (PAM) in the strong hybridization regime. In this regime, the low energy sector of the PAM maps…
Itinerant Ferromagnetism for Mixed Valence Systems
C. D. Batista, J. Bonča, J. E. Gubernatis
We introduce a novel mechanism for the unusual itinerant ferromagnetism found in mixed valence systems like Ce(RhRu)B, LaCeRhB, US, USe, and…
