Investigating Stark many-body localization with continuous unitary transformation flows
Jan-Niklas Herre, Qiyu Liu, Roman Rausch +2
We investigate the ergodicity-to-localization transition in interacting fermion systems subjected to a spatially uniform electric field. For that we employ the recently proposed Te…
Disorder effects in the Fock parafermion chain
G. Camacho, J. Vahedi, D. Schuricht +1
We study the effects of disorder in a one-dimensional model of Fock parafermions which can be viewed as a generalization of the prototypical Kitaev chain. Exact di…
Depth dependent spin dynamics of canonical spin glass films: A low-energy muon spin rotation study
E. Morenzoni, H. Luetkens, T. Prokscha +6
We have performed depth dependent muon spin rotation/relaxation studies of the dynamics of single layer films of {\it Au}Fe and {\it Cu}Mn spin glasses as a function of thickness a…
Anderson localization problem: an exact solution for 2-D anisotropic systems
V. N. Kuzovkov, W. von Niessen
Our previous results [J.Phys.: Condens. Matter 14 (2002) 13777] dealing with the analytical solution of the two-dimensional (2-D) Anderson localization problem due to disorder is g…
Random walk approach to the analytic solution of random systems with multiplicative noise - the Anderson localization problem
V. N. Kuzovkov, W. von Niessen
We discuss here in detail a new analytical random walk approach to calculating the phase-diagram for spatially extended systems with multiplicative noise. We use the Anderson local…
Reply to Comment on "Exact analytic solution for the generalized Lyapunov exponent of the 2-dimensional Anderson localization"
V. N. Kuzovkov, V. Kashcheyevs, W. von Niessen
We reply to comments by P.Marko, L.Schweitzer and M.Weyrauch [preceding paper] on our recent paper [J. Phys.: Condens. Matter 63, 13777 (2002)]. We demonstrate that our…
