Extended s-wave superconductivity in M-point twisted bilayer SnSe2
Lennart Klebl, Ammon Fischer, Salahudin V. Smailagić +6
We investigate the emergence of electronic order and unconventional superconductivity in M-valley moiré materials. Starting from a first-principles Wannier model of AB-stacked twis…
New Crystal Structures Hide in Plain Sight: A Stress Test for AI-Guided Materials Discovery
Xin Zhang, Scott B. Lee, Sudipta Chatterjee +14
New types of crystal structures are discovered only rarely, and the artificial intelligence (AI) models now reshaping materials discovery have so far produced new chemical composit…
Entanglement analysis of isotropic spin-1 chains
Ronny Thomale, Stephan Rachel, B. Andrei Bernevig +1
We investigate entanglement spectra of the SO(3) bilinear-biquadratic spin-1 chain, a model with phases exhibiting spontaneous symmetry breaking (both translation and spin rotation…
Robustness of s-wave Pairing in Electron-Overdoped
Chen Fang, Yang-Le Wu, Ronny Thomale +2
Using self consistent mean field and functional renormalization group approaches we show that s-wave pairing symmetry is robust in the heavily electron-doped iron chalcogenides $(\…
Exotic d-wave superconductivity in strongly hole doped K(x)Ba(1-x)Fe2As2
Ronny Thomale, Christian Platt, Werner Hanke +2
We investigate the superconducting phase in the K(x)Ba(1-x)Fe2As2 122 compounds from moderate to strong hole-doping regimes. Using functional renormalization group, we show that wh…
Why some Iron-based superconductors are nodal while others are nodeless
Ronny Thomale, Christian Platt, Werner Hanke +1
The symmetry of the order parameter in iron-based superconductors, especially the presence or absence of nodes, is still a question of debate. While contradictory experiments can b…
Non-local order in gapless systems: Entanglement Spectrum in Spin Chains
Ronny Thomale, D. P. Arovas, B. Andrei Bernevig
We show that the entanglement spectrum can be used to define non-local order in gapless spin systems. We find a gap that fully separates a series of generic, high `entanglement ene…
Doping-dependent pairing symmetry in the Iron-Pnictides
Ronny Thomale, Christian Platt, Jiangping Hu +2
We use the functional renormalization group method to analyze the phase diagram of a 4-band model for the iron-pnictides subject to band interactions with certain A_{1g} momentum d…
Quasiparticle Scattering Interference in Superconducting Iron-pnictides
Yan-Yang Zhang, Chen Fang, Xiaoting Zhou +4
Using both two orbital and five orbital models, we investigate the quasiparticle interference (QPI) patterns in the superconducting (SC) state of iron-based superconductors. We com…
Novel properties in Josephson junctions involving the cos(kx)cos(ky)-pairing state in iron-pnictides
Wei-Feng Tsai, Dao-Xin Yao, B. Andrei Bernevig +1
We propose a trilayer -junction that takes advantage of the unconventional pairing symmetry which changes sign between electron and hole Fermi po…
Theory of Magnetic Order in
Chen Fang, B. Andrei Bernevig, Jiangping Hu
We develop a local spin model to explain the rich magnetic structures in the iron-based superconductors . We show that our model exhibits both commensurate an…
