Iron pnictide superconductors: Electrons on the verge

Qimiao Si

An optical analysis reveals that the electronic correlations in the `parent' compounds of the iron pnictide superconductors are sufficiently strong to significantly impede the mobi…

Lattice distortion and magnetic quantum phase transition in CeFeAs(1-x)P(x)O

Clarina de la Cruz, W. Z. Hu, Shiliang Li +8

We use neutron scattering to show that replacing the larger arsenic with smaller phosphorus in CeFeAs(1-x)P(x)O simultaneously suppresses the AF order and orthorhombic distortion n…

Finite Momentum Pairing Instability of Band-Insulators With Multiple Bands

Predrag Nikolic, A. A. Burkov, Arun Paramekanti

We show, based on microscopic models, that fermionic band insulators with multiple bands and strong interband attraction are generically unstable towards nonzero momentum Cooper pa…

Superconductivity in Multi-orbital t-J1-J2 Model and its Implications for Iron Pnictides

Pallab Goswami, Predrag Nikolic, Qimiao Si

Motivated by the bad metal behavior of the iron pnictides, we study a multi-orbital model and investigate possible singlet superconducting pairings. Magnetic f…

The phase diagram of two-dimensional fast-rotating ultra-cold fermionic atoms near unitarity

Predrag Nikolic

By analyzing vortex lattices, re-entrant Cooper pairing and Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states in a single theoretical framework we explore how vortices and spin textur…

Correlation effects in the iron pnictides

Qimiao Si, Elihu Abrahams, Jianhui Dai +1

One of the central questions about the iron pnictides concerns the extent to which their electrons are strongly correlated. Here we address this issue through the phenomenology of…

Two-dimensional fermionic superfluids, pairing instability and vortex liquids in the absence of time reversal symmetry

Predrag Nikolic

We consider a generic two-dimensional system of fermionic particles with attractive interactions and no disorder. If time-reversal symmetry is absent, it is possible to obtain inco…
