We examine multiple techniques for extracting information from angle-resolved photoemission spectroscopy (ARPES) data, and test them against simulated spectral functions for electron-phonon coupling. We find that, in the low-coupling regime, it is possible to extract self-energy and bare-band parameters through a self-consistent Kramers-Kronig bare-band fitting routine. We also show that the effective coupling parameters deduced from the renormalization of quasiparticle mass, velocity, and… Expand

‘True’ bosonic coupling strength in strongly correlated superconductors
TLDR
It is demonstrated that the conventional procedure underestimates the electron-boson coupling depending on the electrons-electron coupling, even if the self-energy appears to be self-consistent via the Kramers-Kronig relation. Expand
ARPES: A Probe of Electronic Correlations
Angle-resolved photoemission spectroscopy (ARPES) is one of the most direct methods of studying the electronic structure of solids. By measuring the kinetic energy and angular distribution of theExpand
Systematic study of electron-phonon coupling to oxygen modes across the cuprates
The large variations of T$_c$ across the cuprate families is one of the major unsolved puzzles in condensed matter physics, and is poorly understood. Although there appears to be a great deal ofExpand
Determining the Electron-Phonon Coupling in Superconducting Cuprates by Resonant Inelastic X-ray Scattering: Methods and Results on Nd$_{1+x}$Ba$_{2-x}$Cu$_3$O$_{7-\delta}$
The coupling between lattice vibration quanta and valence electrons can induce charge density modulations and decisively influence the transport properties of materials, e.g. leading to conventionalExpand
High-density two-dimensional electron system induced by oxygen vacancies in ZnO
We realize a two-dimensional electron system (2DES) in ZnO by simply depositing pure aluminum on its surface in ultra-high vacuum, and characterize its electronic structure using angle-resolvedExpand
Evidence for superconductivity in Li-decorated monolayer graphene
Monolayer graphene exhibits many spectacular electronic properties, with superconductivity being arguably the most notable exception. It was theoretically proposed that superconductivity might beExpand

Transition metal oxides (TMOs) are emerging strong players in many domains, ranging from superconductivity, to microelectronics to spintronics to light harvesting for photovoltaics. Beyond theirExpand
Evidence for superconductivity in Li-decorated monolayer graphene
TLDR
It is shown that decorating monolayer graphene with a layer of lithium atoms enhances the electron–phonon coupling to the point where a superconducting state can be stabilized at low temperature, the first observation, to the authors' knowledge, of superconductivity in monolayers graphene. Expand
Designing quantum phases in monolayer graphene
The physics of quantum materials is at the heart of current condensed matter research. The interactions in these materials between electrons themselves, with other excitations, or external fields canExpand
