Quantum phase transition of Ising-coupled Kondo impurities
Markus Garst, Stefan Kehrein, Thomas Pruschke +2
We investigate a model of two Kondo impurities coupled via an Ising interaction. Exploiting the mapping to a generalized single-impurity Anderson model, we establish that the model…
Changes in non-Fermi liquid behavior with annealing due to lattice disorder in UCu_4Pd
C. H. Booth, E. -W. Scheidt, U. Killer +2
The magnetic and electronic properties of non-Fermi liquid UCu_4Pd depend on annealing conditions. Local structural changes due to this annealing are reported from U L_III- and Pd…
Soliton Fermi sea in models of Ising-coupled Kondo impurities
Stefan Kehrein, Matthias Vojta
We study a model of Ising-coupled Kondo impurities that can be applied to quantum dots with capacitance coupling, coupled qubits with an incoherent environment, etc. We show that t…
The finite one-dimensional wire problem
Stefan Kehrein, Christian Muenkel, Kay J. Wiese
We discuss an elementary problem in electrostatics: What does the charge distribution look like for a free charge on a strictly one-dimensional wire of finite length? To the best o…
