Anderson localization in optical lattices with speckle disorder
Sucu, Serpil; Aktaş, Saban; Okan, S. Erol; Akdeniz, Zehra; Vignolo, Patrizia (Amer Physical Soc, 2011)We study the localization properties of noninteracting waves propagating in a speckle-like potential superposed on a one-dimensional lattice. Using a combined decimation-renormalization procedure, we estimate the localization ... -
Localization-delocalization transition in the random dimer model
Schaff, Jean-Francois; Akdeniz, Zehra; Vignolo, Patrizia (Amer Physical Soc, 2010)The random-dimer model is probably the most popular model for a one-dimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the ... -
Spin-charge separation in the quantum boomerang effect
Capuzzi, Pablo; Tessieri, Luca; Akdeniz, Zehra; Minguzzi, Anna; Vignolo, Patrizia (American Physical Society, 2024)We study the localization dynamics of a SU(2) fermionic wave packet launched in a (pseudo)random potential. We show that, in the limit of strong intercomponent repulsions, the total wave packet exhibits a boomeranglike ...
