The one-dimensional t-J model coupled to adiabatic phonons: A numerical investigation
Samuele Bissola, Alberto Parola
The ground state of the one-dimensional t-J model coupled with phonons in the adiabatic limit is numerically investigated by use of the Lanczos technique at quarter filling. Due to…
A microscopic approach to critical phenomena at interfaces: an application to complete wetting in the Ising model
Alberto Orlandi, Alberto Parola, Luciano Reatto
We study how the formalism of the Hierarchical Reference Theory (HRT) can be extended to inhomogeneous systems. HRT is a liquid state theory which implements the basic ideas of Wil…
Transition from 3D to 1D in Bose Gases at Zero Temperature
L. Salasnich, A. Parola, L. Reatto
We investigate the effects of dimensional reduction in Bose gases induced by a strong harmonic confinement in the transverse cylindric radial direction. By using a generalized Lieb…
Non-linear unbalanced Bessel beams: Stationary conical waves supported by nonlinear losses
Miguel A. Porras, Alberto Parola, Daniele Faccio +2
Nonlinear losses accompanying Kerr self-focusing substantially impacts the dynamic balance of diffraction and nonlinearity, permitting the existence of localized and stationary sol…
Magneto-elastic instability in Molecular Antiferromagnetic Rings
L. Spanu, A. Parola
Lattice stability in a model of antiferromagnetic ring coupled to adiabatic phonons is investigated for different values of the spin and numbers of magnetic sites. The magneto-elas…
Dimensional Reduction in Bose-Condensed Alkali-Metal Vapors
L. Salasnich, A. Parola, L. Reatto
We investigate the effects of dimensional reduction in atomic Bose-Einstein condensates (BECs) induced by a strong harmonic confinement in the cylindric radial direction or in the…
