Deep neural networks for inverse problems in mesoscopic physics: Characterization of the disorder configuration from quantum transport properties
Gaëtan J. Percebois, Dietmar Weinmann
We present a machine learning approach that allows to characterize the disorder potential of a two-dimensional electronic system from its quantum transport properties. Numerically…
Algebraic Localization from Power-Law Interactions in Disordered Quantum Wires
Thomas Botzung, Davide Vodola, Piero Naldesi +3
We analyze the effects of disorder on the correlation functions of one-dimensional quantum models of fermions and spins with long-range interactions that decay with distance …
Charge and spin diffusion on the metallic side of the metal-insulator transition: a self-consistent approach
Thomas Wellens, Rodolfo A. Jalabert
We develop a self-consistent theory describing the spin and spatial electron diffusion in the impurity band of doped semiconductors under the effect of a weak spin-orbit coupling.…
Parity-dependent localization in strongly coupled chains
Dietmar Weinmann, S. N. Evangelou
Anderson localization of wave-functions at zero energy in quasi-1D systems of disordered chains with inter-chain coupling is examined. Localization becomes weaker than for…
Meeting experimental challenges to physics of network glasses: assessing role of sample homogeneity
S. Bhosle, K. Gunasekera, P. Chen +3
We introduce a Raman profiling method to track homogenization of GeSe melts in real time, and show that 2 gram melts reacted at 950°C in high vacuum homogenize in 168…
Relaxation mechanism for electron spin in the impurity band of n-doped semiconductors
Pablo I. Tamborenea, Dietmar Weinmann, Rodolfo A. Jalabert
We propose a mechanism to describe spin relaxation in n-doped III-V semiconductors close to the Mott metal-insulator transition. Taking into account the spin-orbit interaction indu…
Fractal time random walk and subrecoil laser cooling considered as renewal processes with infinite mean waiting times
F. Bardou
There exist important stochastic physical processes involving infinite mean waiting times. The mean divergence has dramatic consequences on the process dynamics. Fractal time rando…
Universality of the Lyapunov regime for the Loschmidt echo
Fernando M. Cucchietti, Horacio M. Pastawski, Rodolfo A. Jalabert
The Loschmidt echo (LE) is a magnitude that measures the sensitivity of quantum dynamics to perturbations in the Hamiltonian. For a certain regime of the parameters, the LE decays…
Phase space signatures of the Anderson transition
Andre Wobst, Gert-Ludwig Ingold, Peter Hänggi +1
We use the inverse participation ratio based on the Husimi function to perform a phase space analysis of the Anderson model in one, two, and three dimensions. Important features of…
From ballistic motion to localization: a phase space analysis
Andre Wobst, Gert-Ludwig Ingold, Peter Hänggi +1
We introduce phase space concepts to describe quantum states in a disordered system. The merits of an inverse participation ratio defined on the basis of the Husimi function are de…
Decoherence as Decay of the Loschmidt Echo in a Lorentz Gas
F. M. Cucchietti, H. M. Pastawski, D. A. Wisniacki
Classical chaotic dynamics is characterized by the exponential sensitivity to initial conditions. Quantum mechanics, however, does not show this feature. We consider instead the se…
Environment-independent decoherence rate in classically chaotic systems
Rodolfo A. Jalabert, Horacio M. Pastawski
We study the decoherence of a one-particle system, whose classical correpondent is chaotic, when it evolves coupled to a weak quenched environment. This is done by analytical evalu…
Persistent currents for Coulomb interacting electrons on 2d disordered lattices: Sign and interaction dependence in the Wigner crystal regime
Franck Selva, Dietmar Weinmann
A Wigner crystal structure of the electronic ground state is induced by strong Coulomb interactions at low temperature in clean or disordered two-dimensional (2d) samples. For ferm…
