Length and Localization in One Dimension
The scaling properties of the wave functions in finite samples of the one dimensional Anderson model are analyzed. The states have been characterized using a new form of the information or entropic length, and compared with analytical results obtained by assuming an exponential envelope function. A perfect agreement is obtained already for systems of 10–10 sites over a very wide range of disord...
متن کاملNonlocally-Correlated Disorder and Delocalization in One Dimension II: Localization Length
We study delocalization transition in a one-dimensional Dirac fermion system with random varying mass by using supersymmetric (SUSY) methods. In a previous paper, we calculated density of states and found that (quasi-)extended states near the band center are enhanced by nonlocal correlation of the random Dirac mass. Numerical studies support this conclusion. In this paper, we shall calculate lo...
متن کاملSpin-charge separation and localization in one dimension.
We report on measurements of quantum many-body modes in ballistic wires and their dependence on Coulomb interactions, obtained by tunneling between two parallel wires in an GaAs/AlGaAs heterostructure while varying electron density. We observed two spin modes and one charge mode of the coupled wires and mapped the dispersion velocities of the modes down to a critical density, at which spontaneo...
متن کاملSimulations of transport in one dimension
Advection-dispersion equation is solved in numerically by using combinations of differential quadrature method (DQM) and various time integration techniques covering some explicit or implicit single and multi step methods. Two different initial boundary value problems modeling conservative and nonconservative transports of some substance represented by initial data are chosen as test problems. ...
متن کاملLocalization of Multi-State Quantum Walk in One Dimension
Particle trapping in multi-state quantum walk on a circle is studied. The timeaveraged probability distribution of a particle which moves four different lattice sites according to four internal states is calculated exactly. In contrast with “Hadamard walk” with only two internal states, the particle remains at the initial position with high probability. The time-averaged probability of finding ...
