Noise at the Wigner Glass Transition | | C. Reichhardt

11 Apr 2004 | | Subject: | Strongly Correlated Electrons; Disordered Systems and Neural Networks | cond-mat.str-el cond-mat.dis-nn | | Abstract: | Using a simple model for interacting electrons in two dimensions with random disorder, we show that a crossover from a Wigner liquid to a Wigner glass occurs as a function of charge density. The noise power increases strongly at the transition and the characteristics of the 1/f^alpha noise change. When the temperature is increased, the noise power decreases. We compare these results with recent noise measurements in systems with two-dimensional metal-insulator transitions. | | Source: | arXiv, cond-mat/0404255 | | Services: | Forum | Review | PDF | Favorites | |
