Mesoscopic scattering dynamics under generic uniform SU(2) gauge fields: Spin-momentum relaxation and coherent backscattering
Masataka Kakoi, Christian Miniatura, Keith Slevin
We investigate the time- and momentum-resolved dynamics of matter waves undergoing elastic scattering from a disordered potential in the presence of spatially uniform SU(2) gauge f…
Symmetry-Induced Logarithmic Relaxation in the Quantum Kicked Rotor
Julien Hébraud, Floriane Arrouas, Bruno Peaudecerf +6
We study the effect of discrete symmetries on coherent multiple scattering in the quantum kicked rotor. When the initial momentum is set to zero -- as in recent Bose-Einstein conde…
Kardar-Parisi-Zhang and glassy properties in 2D Anderson localization: eigenstates and wave packets
Noam Izem, Bertrand Georgeot, Jiangbin Gong +2
Despite decades of research, the universal nature of fluctuations in disordered quantum systems remains poorly understood. Here, we present extensive numerical evidence that fluctu…
2D Anderson Localization and KPZ sub-Universality Classes : sensitivity to boundary conditions and insensitivity to symmetry classes
Nyayabanta Swain, Shaffique Adam, Gabriel Lemarié
We challenge two foundational principles of localization physics by analyzing conductance fluctuations in two dimensions with unprecedented precision: (i) the Thouless criterion, w…
Critical Dynamics of the Anderson Transition on Small-World Graphs
Weitao Chen, Ignacio García-Mata, John Martin +3
The Anderson transition on random graphs draws interest through its resemblance to the many-body localization (MBL) transition with similarly debated properties. In this Letter, we…
Universal fluctuations of localized two interacting particles in one dimension
Sen Mu, Gabriel Lemarié, Jiangbin Gong
We investigate the universal fluctuations of localized wavefunction in the Fock space of two interacting particles in one-dimensional disordered systems, focusing on the interplay…
