Atom-molecule coherence in a one-dimensional system
R. Citro, E. Orignac
We study a model of one-dimensional fermionic atoms that can bind in pairs to form bosonic molecules. We show that at low energy, a coherence develops between the molecule and ferm…
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,…
Nonlocal pure spin current injection via quantum pumping and crossed Andreev reflection
Colin Benjamin, Roberta Citro
A pure spin current injector is proposed based on adiabatic pumping and crossed normal/Andreev reflection. The device consists of a three-terminal ferromagnet-superconductor-semico…
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…
Magnetostriction in an array of spin chains under magnetic field
E. Orignac, R. Citro
We consider an array of XX spin-1/2 chains coupled to acoustic phonons and placed in a magnetic field. Treating the phonons in the mean field approximation, we show that this syste…
