Metal-insulator transition in the quarter- filled frustrated checkerboard lattice
Y. Z. Zhang, Tran Minh-Tien, V. Yushankhai +1
We study the electronic structure and correlations in the geometrically frustrated two dimensional checkerboard lattice. In the large U limit considered here we start from an exten…
Superconductivity in heavy fermion compounds
P. Thalmeier, G. Zwicknagl, O. Stockert +2
We review the current state of experimental and theoretical investigations of heavy fermion superconductors. We discuss most of the Ce-based compounds like Ce122, Ce115, Ce218 and…
Gap Symmetry and Thermal Conductivity in Nodal Superconductors
H. Won, K. Maki
Here we consider the universal heat conduction and the angular dependent thermal conductivity in the vortex state for a few nodal superconductors. We present the thermal conductivi…
Third-order magnetic susceptibility of the frustrated square-lattice antiferromagnet
Burkhard Schmidt, Peter Thalmeier
We present results from our analysis of the finite-temperature properties of the spin 1/2 - Heisenberg model on a square lattice. The analysis is based on the exact d…
Superconducting Gap Function in Antiferromagnetic Heavy-Fermion UPd_2Al_3 Probed by Angle Resolved Magnetothermal Transport Measurements
T. Watanabe, K. Izawa, Y. Kasahara +5
The superconducting gap structure of heavy fermion UPd_2Al_3, in which unconventional superconductivity coexists with antiferromagnetic (AF) order with atomic size local moments, w…
Four-well tunneling states and elastic response of clathrates
I. Zerec, V. Keppens, M. A. McGuire +3
We present resonant ultrasound elastic constant measurements of the clathrate compounds Eu8Ga16Ge30 and Sr8Ga16Ge30. The elastic response of the Eu clathrate provides clear evidenc…
