Breakdown of universal transport in correlated d-wave superconductors
Brian M. Andersen, P. J. Hirschfeld
The prediction and observation of low-temperature universal thermal conductivity in cuprates has served as a keystone of theoretical approaches to the superconducting state, but re…
Magnetic and superfluid phases of confined fermions in two-dimensional optical lattices
Brian M. Andersen, G. M. Bruun
We examine antiferromagnetic and d-wave superfluid phases of cold fermionic atoms with repulsive interactions in a two-dimensional optical lattice combined with a harmonic trapping…
Novel Josephson Effects in d-wave Superconductor Junctions with Antiferromagnetic Interlayers
Brian M. Andersen, Yu. S. Barash, S. Graser +1
We calculate the dc supercurrent through a Josephson tunnel junction consisting of an antiferromagnetic (AF) interlayer sandwiched between two d-wave superconductors (d). Such d/AF…
Superconducting gap variations induced by structural supermodulation in BSCCO
Brian M. Andersen, P. J. Hirschfeld, James A. Slezak
We discuss the possibility that the strain field introduced by the structural supermodulation in Bi-2212 and certain other cuprate materials may modulate the superconducting pairin…
Kondo-Enhanced Andreev Tunneling in InAs Nanowire Quantum Dots
T. Sand-Jespersen, J. Paaske, B. M. Andersen +7
We report measurements of the nonlinear conductance of InAs nanowire quantum dots coupled to superconducting leads. We observe a clear alternation between odd and even occupation o…
