Femtosecond electron-phonon lock-in by photoemission and x-ray free-electron laser
TLDR
The electron-phonon coupling strength in FeSe can be quantified by combining two time-domain experiments into a “coherent lock-in” measurement in the terahertz regime using photoemission spectroscopy and x-ray diffraction.
Coexistence of Replica Bands and Superconductivity in FeSe Monolayer Films.
TLDR
A systematic comparison of 1 ML FeSe on TiO_{2} with other systems in the FeSe family shows that while charge transfer alone can enhance T_{ c}, it is only with the addition of interfacial electron-phonon coupling that T_{c} can be increased to the level seen in 1  ML Fe Se on STO.
Strong correlations and orbital texture in single-layer 1T-TaSe2
Strong electron correlation can induce Mott insulating behaviour and produce intriguing states of matter such as unconventional superconductivity and quantum spin liquids. Recent advances in van der
Simultaneous emergence of superconductivity, inter-pocket scattering and nematic fluctuation in potassium-coated FeSe superconductor
Superconductivity originates from pairing of electrons. Pairing channel on Fermi surface and pairing glue are thus two pivotal issues for understanding a superconductor. Recently, high-temperature
Visualizing Exotic Orbital Texture in the Single-Layer Mott Insulator 1T-TaSe2
Mott insulating behavior is induced by strong electron correlation and can lead to exotic states of matter such as unconventional superconductivity and quantum spin liquids. Recent advances in van
Ubiquitous strong electron–phonon coupling at the interface of FeSe/SrTiO3
TLDR
The ARPES study of the electronic structure of FeSe/STO(110) suggests that the large superconducting gaps observed in FeSe films grown on different STO surface terminations are likely enhanced by a common mechanism.
Origin of the low critical observing temperature of the quantum anomalous Hall effect in V-doped (Bi, Sb)2Te3 film
TLDR
This work systematically study the band structure of V-doped (Bi, Sb)2Te3 thin films by angle-resolved photoemission spectroscopy (ARPES) and shows unambiguously that the bulk valence band (BVB) maximum lies higher in energy than the surface state Dirac point.
Fermi surface reconstruction in electron-doped cuprates without antiferromagnetic long-range order
Significance Fermi surface (FS) topology is a fundamental property of metals and superconductors. In electron-doped cuprate Nd2−xCexCuO4, an unexpected FS reconstruction has been observed in optimal-
Universal Substrate Effect on the Superconductivity of FeSe Monolayer Films

Dichotomy of the photo-induced 2-dimensional electron gas on SrTiO3 surface terminations
TLDR
Using layer-by-layer growth of high-quality STO films, it is shown that the 2DEG only forms with the SrO termination and not with the TiO2 termination, contrary to expectation.
