Is the Multichannel Kondo Model Appropriate to Describe the Single Electron Transistor?
Gergely Zarand, Gergely T. Zimanyi, Frank Wilhelm
We investigate the low-temperature dynamics of single electron boxes and transistors close to their degeneracy point using renormalization group methods. We show that intermode sca…
Disorder and Impurities in Hubbard-Antiferromagnets
M. Ulmke, P. J. H. Denteneer, V. Janis +4
We study the influence of disorder and randomly distributed impurities on the properties of correlated antiferromagnets. To this end the Hubbard model with (i) random potentials, (…
Instability of the marginal commutative model of tunneling centers interacting with metallic environment: Role of the electron-hole symmetry breaking
A. Zawadowski, G. Zarand, P. Nozieres +2
The role of the electron-hole symmetry breaking is investigated for a symmetrical commutative two-level system in a metal using the multiplicative renormalization group in a straig…
