Mobility Edge in the Anderson Model on Partially Disordered Random Regular Graphs

نویسندگان

چکیده

In this Letter we study numerically the Anderson model on partially disordered random regular graphs (RRG) considered as toy for a Hilbert space of interacting many-body system. The protected subsector zero-energy states in system corresponds to clean nodes RRG ensemble. Using adjacent gap ratio statistics and IPR find sharp mobility edge spectrum one-particle above some critical density nodes. Its position is almost independent disorder strength. possible application our result controversial issue localized (MBL) phase discussed.

Majority Model on Random Regular Graphs

Consider a graph G = (V, E) and an initial random coloring where each vertex v ∈ V is blue with probability Pb and red otherwise, independently from all other vertices. In each round, all vertices simultaneously switch their color to the most frequent color in their neighborhood and in case of a tie, a vertex keeps its current color. The main goal of the present paper is to analyze the behavior...

Partially Distance-regular Graphs and Partially Walk-regular Graphs∗

We study partially distance-regular graphs and partially walkregular graphs as generalizations of distance-regular graphs and walkregular graphs respectively. We conclude that the partially distanceregular graphs can be viewed as some extremal graphs of partially walk-regular graphs. In the special case that the graph is assumed to be regular with four distinct eigenvalues, a well known class o...

The generalised acyclic edge chromatic number of random regular graphs

The r-acyclic edge chromatic number of a graph is defined to be the minimum number of colours required to produce an edge colouring of the graph such that adjacent edges receive different colours and every cycle C has at least min(|C|, r) colours. We show that (r − 2)d is asymptotically almost surely (a.a.s.) an upper bound on the r-acyclic edge chromatic number of a random d-regular graph, for...
