Huge Positive Magnetoresistance in Antiferromagnetic Double Perovskite Metals
Viveka Nand Singh, Pinaki Majumdar
Metals with large positive magnetoresistance are rare. We demonstrate that antiferromagnetic metallic states, as have been predicted for the double perovskites, are excellent candi…

Thermally Fluctuating Inhomogeneous Superfluid State of Strongly Interacting Fermions in an Optical Lattice
Viveka Nand Singh, Sanjoy Datta, Pinaki Majumdar
The presence of attractive interaction between fermions can lead to pairing and superfluidity in an optical lattice. The temperature needed to observe superfluidity is about a tent…
