BCS pairing in Fermi systems with several flavors
Carsten Honerkamp, Walter Hofstetter
Motivated by the prospect of Bardeen-Cooper-Schrieffer (BCS) pairing in cold fermionic gases we analyze the superfluid phase of 3 fermionic flavors in the attractive Hubbard model.…
Ultracold fermions and the SU(N) Hubbard model
Carsten Honerkamp, Walter Hofstetter
We investigate the fermionic SU(N) Hubbard model on the two-dimensional square lattice for weak to moderate interaction strengths using one-loop renormalization group and mean-fiel…
Singlet-triplet transition in a lateral quantum dot
M. Pustilnik, L. I. Glazman, W. Hofstetter
We study transport through a lateral quantum dot in the vicinity of the singlet-triplet transition in its ground state. This transition, being sharp in an isolated dot, is broadene…
Numerical Renormalization Group Analysis of Interacting Quantum Dots
Walter Hofstetter
Wilson's Numerical Renormalization Group (NRG) is so far the only nonperturbative technique that can reliably access low-energy properties of quantum impurity systems. We present a…
