Sound attenuation and velocity shift in antiferromagnetic spin-1/2 chains
Edmond Orignac, Emeric Caprani, Roberta Citro
We investigate ultrasound attenuation and sound velocity shift in antiferromagnetic spin-1/2 XXZ chains in magnetic field. We relate the sound velocity shift to derivatives of the…
Supercurrent from the imaginary part of the Andreev levels in non-Hermitian Josephson junctions
Roberto Capecelatro, Marco Marciani, Gabriele Campagnano +2
We investigate the electronic transport properties of a superconductor-quantum dot-superconductor Josephson junction coupled to a ferromagnetic metal reservoir in the presence of a…
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…
Quantum phases of spinful Fermi gases in optical cavities
E. Colella, R. Citro, M. Barsanti +2
We explore the quantum phases emerging from the interplay between spin and motional degrees of freedom of a one-dimensional quantum fluid of spinful fermionic atoms, effectively in…
Diagrammatic theory for Periodic Anderson Model: Stationary property of the thermodynamic potential
V. A. Moskalenko, L. A. Dohotaru, R. Citro
Diagrammatic theory for Periodic Anderson Model has been developed, supposing the Coulomb repulsion of localized electrons as a main parameter of the theory. electrons ar…
Diagrammatic theory for Anderson Impurity Model. Stationary property of the thermodynamic potential
V. A. Moskalenko, P. Entel, L. A. Dohotaru +1
A diagrammatic theory around atomic limit is proposed for normal state of Anderson Impurity Model. The new diagram method is based on the ordinary Wick's theorem for conduction ele…
