Critical Berezinskii-Kosterlitz-Thouless dynamics in the archetypal two-dimensional spin system BaCuSiOCl
K. M. Ranjith, Maxime Dupont, Steffen Krämer +6
We study the spin dynamics in the quasi-2D spin- dimer compound BaCuSiOCl, which exhibits a magnetic field-induced Bose-Einstein condensate (BEC) of triplons.…
Superconductivity in the repulsive Hubbard model on different geometries induced by density-assisted hopping
Franco T. Lisandrini, Edmond Orignac, Roberta Citro +2
We study the effect of density-assisted hopping on different dimerized lattice geometries, such as bilayers and ladder structures. We show analytically that the density-assisted ho…
One dimensional Bose-Hubbard model with long range hopping
Edmond Orignac
Interacting one-dimensional bosons with long range hopping decaying as a power law with distance are considered with the renormalization group and the self-consistent…
Platforms for the realization and characterization of Tomonaga-Luttinger liquids
Isabelle Bouchoule, Roberta Citro, Tim Duty +5
The concept of a Tomonaga-Luttinger liquid (TLL) has been established as a fundamental theory for the understanding of one-dimensional quantum systems. Originally formulated as a r…
