s-wave Cooper pair insulators and theory of correlated superconductors
Predrag Nikolic, Zlatko Tesanovic
The pseudogap state of cuprate high-temperature superconductors has been often viewed as either a yet unknown competing order or a precursor state to superconductivity. While await…
Pair density wave instability and Cooper pair insulators in gapped fermion systems
Predrag Nikolic, Anton A. Burkov, Arun Paramekanti
By analyzing simple models of fermions in lattice potentials we argue that the zero-temperature pairing instability of any ideal band-insulator occurs at a finite momentum. The res…
Unitarity in periodic potentials: a renormalization group analysis
Predrag Nikolic
We explore the universal properties of interacting fermionic lattice systems, mostly focusing on the development of pairing correlations from attractive interactions. Using renorma…
Robust accidental nodes and zeroes and critical quasiparticle scaling in iron-based multiband superconductors
Valentin Stanev, Boian S. Alexandrov, Predrag Nikolic +1
We study multigap superconductivity, with strong angular variations of one of the gaps, as appropriate for certain iron-based high-temperature superconductors. We solve the gap equ…
Engineering Time-Reversal Invariant Topological Insulators With Ultra-Cold Atoms
N. Goldman, I. Satija, P. Nikolic +4
Topological insulators are a broad class of unconventional materials that are insulating in the interior but conduct along the edges. This edge transport is topologically protected…
