Collapse-driven spatiotemporal dynamics of filament formation
Miguel A. Porras, Alberto Parola, Daniele Faccio +2
The transition from spatial to spatiotemporal dynamics in Kerr-driven beam collapse is modelled as the instability of the Townes profile. Coupled axial and conical radiation, tempo…
Thermodynamics of Solitonic Matter Waves in a Toroidal Trap
L. Salasnich, A. Parola, L. Reatto
We investigate the thermodynamic properties of a Bose-Einstein condensate with negative scattering length confined in a toroidal trapping potential. By numerically solving the coup…
Dimensional Effects on Solitonic Matter and Optical Waves with Normal and Anomalous Dispersion
L. Salasnich, A. Parola, L. Reatto
We investigate bright and dark solitons with anomalous or normal dispersion and under transverse harmonic confinement. In matter waves, positive atomic mass implies anomalous dispe…
Competitive density waves in quasi-one-dimensional electron systems
Samuele Bissola, Alberto Parola
We investigate the nature of the ground state of the one-dimensional t-J model coupled to adiabatic phonons by use of the Lanczos technique at quarter filling. Due to the interplay…
Freezing and correlations in fluids with competing interactions
D. Pini, A. Parola, L. Reatto
We consider fluids where the attractive interaction at distances slightly larger than the particle size is dominated at larger distances by a repulsive contribution. A previous inv…
The Ising phase in the J1-J2 Heisenberg Model
V. Lante, A. Parola
The two dimensional Heisenberg antiferromagnet on the square lattice with nearest (J1) and next-nearest (J2) neighbor couplings is investigated in the strong frustration regime (J2…
