X and Y waves in the spatiotemporal Kerr dynamics of a self-guided light beam
Miguel A. Porras, Alberto Parola
The nonlinear stage of development of the spatiotemporal instability of the monochromatic Townes beam in a medium with self-focusing nonlinearity and normal dispersion is studied b…
Nonlinear unbalanced Bessel beams in the collapse of Gaussian beams arrested by nonlinear losses
Miguel A. Porras, Alberto Parola
Collapse of a Gaussian beam in self-focusing Kerr media arrested by nonlinear losses may lead to the spontaneous formation of a quasi-stationary nonlinear unbalanced Bessel beam wi…
Role of backflow correlations for the non-magnetic phase of the t-t' Hubbard model
Luca F. Tocchio, Federico Becca, Alberto Parola +1
We introduce an efficient way to improve the accuracy of projected wave functions, widely used to study the two-dimensional Hubbard model. Taking the clue from the backflow contrib…
Liquid-vapor transition from a microscopic theory: Beyond the Maxwell construction
Alberto Parola, Davide Pini, Luciano Reatto
A smooth cut-off formulation of the Hierarchical Reference Theory (HRT) is developed and applied to a Yukawa fluid. The HRT equations are derived and numerically solved leading to:…
