The low-energy excitation spectrum of one-dimensional dipolar quantum gases
S. De Palo, E. Orignac, R. Citro +1
We determine the excitation spectrum of a bosonic dipolar quantum gas in a one-dimensional geometry, from the dynamical density-density correlation functions simulated by means of…
Critical properties and Bose Einstein Condensation in dimer spin systems
E. Orignac, R. Citro, T. Giamarchi
We analyze the spin relaxation time for a system made of weakly coupled one dimensional ladders.This system allows to probe the dimensional crossover between a Luttinger li…
A novel diagrammatic technique for the single-site Anderson model
V. A. Moskalenko, P. Entel, D. F. Digor +2
A diagrammatic theory around the atomic limit is proposed for the single-impurity Anderson model in which the strongly correlated impurity electrons hybridize with free (uncorrelat…
Pressure dependence of superconducting and magnetic critical temperatures in the ruthenocuprates
R. Citro, G. G. N. Angilella, M. Marinaro +1
We study the dependence on filling and pressure of the superconducting and ferromagnetic critical temperatures of the ruthenocuprates, within the two-band model. At zero pressure,…
Adiabatic-antiadiabatic crossover in a spin-Peierls chain
R. Citro, E. Orignac, T. Giamarchi
We consider an XXZ spin-1/2 chain coupled to optical phonons with non-zero frequency . In the adiabatic limit (small ), the chain is expected to spontaneously dimerize an…
