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…

Orbital Kondo-effect from tunneling impurities
G. Zarand, K. Vladar
The article reviews recent results for the low energy physics of fast tunneling centers in metallic environments. For strong enough couplings to the environment these tunneling cen…
