Bosonization approach to the mixed-valence two-channel Kondo problem
A. Iucci, C. J. Bolech
We present in detail the bosonization-refermionization solution of the anisotropic version of the two-channel Anderson model at a particular manifold in the space of parameters of…
Fourier transform of the Luttinger liquid density correlation function with different spin and charge velocities
A. Iucci, G. A. Fiete, T. Giamarchi
We obtain a closed-form analytical expression for the zero temperature Fourier transform of the component of the density-density correlation function in a Luttinger liquid w…
Competition between Vortex Unbinding and Tunneling in an Optical Lattice
M. A. Cazalilla, A. Iucci, T. Giamarchi
We study a system of two-dimensional Bose gases trapped in minima of a deep one-dimensional optical lattice potential. Increasing the tunneling amplitude between adjacent gases dri…
Bosonization of Luttinger liquids: spin flipping interactions and spin-orbit coupling
Anibal Iucci
In this thesis we present contributions in the field of the applications of quantum field theories techniques to condensed matter models. In chapter 3 we investigate on the non cov…
