    • Hip-hop solutions of the 2N-body problem 

      Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol Pérez, Conxita; Soler Villanueva, Jaume (2006-09)
      Article
      Accés obert
      Hip–Hop solutions of the 2N–body problem with equal masses are shown to exist using an analytic continuation argument. These solutions are close to planar regular 2N–gon relative equilibria with small vertical oscillations. ...

    • Operations with regular holonomic D-modules with support a normal crossing 

      Álvarez Montaner, Josep (2003)
      Article
      Accés obert
      The aim of this work is to describe some operations in the category of regular holonomic $\cD$-modules with support a normal crossing and variation zero introduced in [J.Alvarez Montaner, R.Garcia Lopez and S.Zarzuela, ...

    • Quantum Monte Carlo estimation of complex-time correlations for the study of the ground-state dynamic structure function 

      Rota, R; Casulleras Ambrós, Joaquín; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (2015-03-21)
      Article
      Accés obert
      We present a method based on the path integral Monte Carlo formalism for the calculation of ground-state time correlation functions in quantum systems. The key point of the method is the consideration of time as a complex ...
