Pairing symmetries in the Zeeman-coupled extended attractive Hubbard model
By introducing the possibility of equal- and opposite-spin pairings concurrently, we show that the ground state of the extended attractive Hubbard model (EAHM) exhibits rich phase diagrams with aExpand

Multiband theory of superconductivity at the LaAlO 3 /SrTiO 3 interface
We present a multi-band model for superconductivity at the metallic interface between insulating oxides LaAlO$_3$ and SrTiO$_3$ (001). Using a self-consistent Bogoliubov-de Gennes theory, formulatedExpand
Enhanced critical temperature, pairing fluctuation effects, and BCS-BEC crossover in a two-band Fermi gas
We study the superfluid critical temperature in a two-band attractive Fermi system with strong pairing fluctuations associated with both interband and intraband couplings. We focus specifically on aExpand
Polaronic metal state at the LaAlO3/SrTiO3 interface
TLDR
Soft-X-ray angle-resolved photoelectron spectroscopy is used to penetrate through the LaAlO3 overlayer and access charge carriers at the buried interface and directly identifies the interface charge carriers as large polarons, emerging from coupling of charge and lattice degrees of freedom. Expand
Scattering and Pairing in Cuprate Superconductors
The origin of the exceptionally strong superconductivity of cuprates remains a subject of debate after more than two decades of investigation. Here we follow a new lead: The onset temperature forExpand
Band inversion driven by electronic correlations at the (111) LaAlO3/SrTiO3 interface
Quantum confinement at complex oxide interfaces establishes an intricate hierarchy of the strongly correlated d orbitals which is widely recognized as a source of emergent physics. The most prominentExpand
Topological superconductivity and unconventional pairing in oxide interfaces.
TLDR
This work proposes an unconventional pairing state for the electron fluid in two-dimensional oxide interfaces and establishes a direct link to the emergence of non-trivial topological invariants, which can be used to detect the microscopic origin of superconductivity. Expand

TLDR
A phase diagram for the superconducting groundstates is presented and the density of states, the spectra, and the momentum distribution functions of the different phases are analyzed. Expand
Experimental evidence of cubic Rashba effect in an inversion-symmetric oxide.
We present evidence of cubic Rashba spin splitting in a quasi-two-dimensional electron gas formed at a surface of (001) SrTiO3 single crystal from the weak localization or antilocalization (WAL)Expand
Back to Mechanisms of Superconductivity in Low-Doped Strontium Titanate
We have analyzed two mechanisms proposed recently for superconductivity in doped SrTiO3 - the plasmon-mediated pairing and the potential of an instantaneous attraction between two electrons that owesExpand
Gap suppression at a Lifshitz transition in a multi-condensate superconductor
TLDR
This work uses resonant microwave transport to extract the superfluid stiffness of the (110)-oriented LaAlO3/SrTiO3 interface in the entire phase diagram and finds that the superconducting gap is suppressed while the second band is populated, challenging Bardeen–Cooper–Schrieffer theory. Expand
