Magnetic field induced transition from nodeless to nodal superconductivity in -PdBi
Emmanouil K. Kokkinis, Joseph J. Betouras, Andrey V. Chubukov
Recent tunneling measurements on -PdBi reported a magnetic field induced phase transition from a fully gapped to a nodal superconducting state. We develop a microscopic the…

Pseudogap in electron-doped cuprates: thermal precursor to magnetism
Emmanouil K. Kokkinis, Andrey V. Chubukov
We study pseudogap behavior in a metal near an antiferromagnetic instability and apply the results to electron-doped cuprates. We associate pseudogap behavior with thermal magnetic…

An unusual first order phase transition in a 2D superconductor
Noah J. Jabusch, Emmanouil K. Kokkinis, Andrey V. Chubukov
We consider a superconductor under external perturbation, which forces Cooper pairs to develop with a finite total momentum . The condensation energy of such a state decreases w…
