Pairing instability on a Luttinger surface: A non-Fermi liquid to superconductor transition and its Sachdev-Ye-Kitaev dual
Chandan Setty
Superconductivity results from an instability of the Fermi surface -- contour of \textit{poles} of the single particle propagator -- to an infinitesimally small attraction between…
Pressure Effects on Magnetically-Driven Electronic Nematic States in Iron-Pnictides
Jiangping Hu, Chandan Setty, Steve Kivelson
In a magnetically driven electronic nematic state, an externally applied uniaxial strain rounds the nematic transition and increases the magnetic transition temperature. We study b…
Spin fluctuations in the ultranodal superconducting state of Fe(Se,S)
Yifu Cao, Chandan Setty, Andreas Kreisel +2
The iron-based superconductor FeSe isovalently substituted with S displays an abundance of remarkable phenomena that have not been fully understood, at the center of which are appa…
Topological Ultranodal pair states in iron-based superconductors
Chandan Setty, Shinibali Bhattacharyya, Yifu Cao +2
Bogoliubov Fermi surfaces are contours of zero-energy excitations that are protected in the superconducting state. Here we show that multiband superconductors with dominant spin si…
Realizing infrared power-law liquids in the cuprates from unparticle interactions
Kridsanaphong Limtragool, Chandan Setty, Zhidong Leong +1
Recent photoemission experiments \cite{dessau} reveal that the excitations along the nodal region in the strange metal of the cuprates, rather than corresponding to poles in the si…
Observation of Flat Bands and Dirac Cones in a Pyrochlore Lattice Superconductor
Jianwei Huang, Chandan Setty, Liangzi Deng +21
Emergent phases often appear when the electronic kinetic energy is comparable to the Coulomb interactions. One approach to seek material systems as hosts of such emergent phases is…
