Enhanced superconductivity in FeSe/SrTiO from the combination of forward scattering phonons and spin fluctuations
Louk Rademaker, Gustavo Alvarez-Suchini, Ken Nakatsukasa +2
We study the effect of combining spin fluctuations and forward scattering electron-phonon ({\eph}) coupling on the superconductivity in the FeSe/SrTiO system modeled by a pheno…
Detection of magnetic impurities using electron vortex beams
Yan Wang, Chenglong Jia, Pengming Zhang
Electron microscopy stands out as electron waves providing higher spatial resolving power compared to their optical counterpart. Here we investigate theoretically the interaction o…
Determining the Electron-Phonon Coupling in Superconducting Cuprates by Resonant Inelastic X-ray Scattering: Methods and Results on NdBaCuO
Lucio Braicovich, Matteo Rossi, Roberto Fumagalli +15
The coupling between lattice vibration quanta and valence electrons can induce charge density modulations and decisively influence the transport properties of materials, e.g. leadi…
Temperature-filling phase diagram of the two-dimensional Holstein model in the thermodynamic limit by self-consistent Migdal approximation
Philip M. Dee, Ken Nakatsukasa, Yan Wang +1
We study the temperature-filling phase diagram of the single-band Holstein model in two dimensions using the self-consistent Migdal approximation, where both the electron and phono…
Lattice Dynamics of Ultrathin FeSe Films on SrTiO3
Shuyuan Zhang, Jiaqi Guan, Yan Wang +14
Charge transfer and electron-phonon coupling (EPC) are proposed to be two important constituents associated with enhanced superconductivity in the single unit cell FeSe films on ox…
Phonon linewidth due to electron-phonon interactions with strong forward scattering in FeSe thin films on oxide substrates
Yan Wang, Louk Rademaker, Elbio Dagotto +1
The discovery of an enhanced superconducting transition temperature in monolayers of FeSe grown on several oxide substrates has opened a new route to high- superconducti…
Non-local correlations in the orbital selective Mott phase of a one dimensional multi-orbital Hubbard model
Shaozhi. Li, N. Kaushal, Y. Wang +6
We study non-local correlations in a three-orbital Hubbard model defined on an extended one-dimensional chain using determinant quantum Monte Carlo and density matrix renormalizati…
High Tc via spin fluctuations from incipient bands: application to monolayers and intercalates of FeSe
A. Linscheid, S. Maiti, Y. Wang +2
We investigate superconductivity in a two-band system with an electron- and hole-like band, where one of the bands is away from the Fermi level (or incipient). We argue that the in…
Orbital-selective Mott phases of a one-dimensional three-orbital Hubbard model studied using computational techniques
Guangkun Liu, Nitin Kaushal, Shaozhi Li +6
A recently introduced one-dimensional three-orbital Hubbard model displays orbital-selective Mott phases with exotic spin arrangements such as spin block states [J. Rincón {\em et…
Ab initio Study of Cross-Interface Electron-Phonon Couplings in FeSe Thin Films on SrTiO and BaTiO
Yan Wang, Andreas Linscheid, Tom Berlijn +1
We study the electron-phonon coupling strength near the interface of monolayer and bilayer FeSe thin films on SrTiO, BaTiO, and oxygen-vacant SrTiO substrates, using ab…
Aspects of electron-phonon interactions with strong forward scattering in FeSe Thin Films on SrTiO substrates
Y. Wang, K. Nakatsukasa, L. Rademaker +2
Mono- and multilayer FeSe thin films grown on SrTiO and BiTiO substrates exhibit a greatly enhanced superconductivity over that found in bulk FeSe. A numb…
Enhanced superconductivity due to forward scattering in FeSe thin films on SrTiO3 substrates
Louk Rademaker, Yan Wang, Tom Berlijn +1
We study the consequences of an electron-phonon (-) interaction that is strongly peaked in the forward scattering () direction in a two-dimensional supercond…
Emergent defect states as a source of resistivity anisotropy in the nematic phase of iron pnictides
Maria N. Gastiasoro, I. Paul, Y. Wang +2
We consider the role of potential scatterers in the nematic phase of Fe-based superconductors above the transition temperature to the (pi,0) magnetic state but below the orthorhomb…
Effects of disordered Ru substitution in BaFeAs: Realization of superdiffusion mechanism in real materials
Limin Wang, Tom Berlijn, Yan Wang +3
An unexpected insensitivity of the Fermi surface to impurity scattering is found in Ru substituted BaFeAs from first-principles theory, offering a natural explanation of th…
