Topological density wave states of non-zero angular momentum

Chen-Hsuan Hsu, S. Raghu, Sudip Chakravarty

The pseudogap state of high temperature superconductors is a profound mystery. It has tantalizing evidence of a number of broken symmetry states, not necessarily conventional charg…

The magnetic phase diagram of an extended J1-J2 model on a modulated square lattice and its implications for the antiferromagnetic phase of KyFexSe2

Rong Yu, Pallab Goswami, Qimiao Si

Motivated by the experimentally observed iron vacancy order and a block spin antiferromagnetic phase with large magnetic moment in $\mathrm{K}_{0.8}\math…

Local Electronic Structure around a Single Impurity as a Test of Pairing Symmetry in (K,Tl)FeSe Superconductors

Jian-Xin Zhu, Rong Yu, A. V. Balatsky +1

We have studied the effect of a single nonmagnetic impurity in the recently discovered (K,Tl)FeSe superconductors, within both a toy two-band model and a more realistic fiv…

Superconductivity at the Border of Electron Localization and Itinerancy

Rong Yu, Pallab Goswami, Qimiao Si +2

The superconducting state of iron pnictides and chalcogenides exists at the border of antiferromagnetic order. Consequently, these materials could provide clues about the relations…

Composite pairing in a mixed valent two channel Anderson model

Rebecca Flint, Andriy H. Nevidomskyy, Piers Coleman

Using a two-channel Anderson model, we develop a theory of composite pairing in the 115 family of heavy fermion superconductors that incorporates the effects of f-electron valence…

Numerical Simulation of the Nernst Effect in Extreme Type-II Superconductors: A Negative Nernst Signal and its Noise Power Spectra

Sangwoo S. Chung, Paata Kakashvili, C. J. Bolech

Recently, different transport coefficients have been measured in High-Tc superconductors to pinpoint the nature of the pseudogap phase. In particular, the thermoelectric coefficien…

Mott transition in Modulated Lattices and Parent Insulator of (K,Tl)yFexSe2 Superconductors

Rong Yu, Jian-Xin Zhu, Qimiao Si

The degree of electron correlations remains a central issue in the iron-based superconductors. The parent iron pnictides are antiferromagnetic, and their bad-metal behavior has bee…
