Light scattering in inhomogeneous Tomonaga-Luttinger liquids
E. Orignac, R. Citro, S. De Palo +1
We derive the dynamical structure factor for an inhomogeneous Tomonaga-Luttinger liquid as can be formed in a confined strongly interacting one-dimensional gas. In view of current…
Scattering theory of magnetic/superconducting junctions with spin active interfaces
F. Romeo, R. Citro
We formulate a generalized scattering field theory a la Buttiker describing particles transport in magnetic/superconducting heterostructures. The proposed formalism, characterized…
Quantum dynamics of a binary mixture of BECs in a double well potential: an Holstein-Primakoff approach
Roberta Citro, Adele Naddeo, Edmond Orignac
We study the quantum dynamics of a binary mixture of Bose-Einstein condensates (BEC) in a double-well potential starting from a two-mode Bose-Hubbard Hamiltonian. Focussing on the…
Charge transfer and trapping as origin of a double dip in the transfer characteristics of graphene based field-effect transistors
Antonio Di Bartolomeo, Filippo Giubileo, Salvatore Santandrea +4
We discuss the origin of an additional dip other than the charge neutrality point observed in transfer characteristics of graphene-based field-effect transistors. The double-dip is…
One dimensional Bosons: From Condensed Matter Systems to Ultracold Gases
M. A. Cazalilla, R. Citro, T. Giamarchi +2
We review the physics of one-dimensional interacting bosonic systems. Beginning with results from exactly solvable models and computational approaches, we introduce the concept of…
