We review the intermediate coupling model for treating electronic correlations in the
cuprates. Spectral signatures of the intermediate coupling scenario are identified and used …

Theories based on the coupling between spin fluctuations and fermionic quasiparticles are
among the leading contenders to explain the origin of high-temperature superconductivity …

Nonequilibrium pump-probe time-domain spectroscopies can become an important tool to
disentangle degrees of freedom whose coupling leads to broad structures in the frequency …

The excitations responsible for producing high-temperature superconductivity in the copper
oxides have yet to be identified. Two promising candidates are collective spin excitations …

This review outlines fundamental principles, instrumentation, and capabilities of angle-
resolved photoemission spectroscopy (ARPES) and microscopy. We will present how high …

The nonequilibrium state of the high-T c superconductor Bi 2 Sr 2 CaCu 2 O 8+ δ and its
ultrafast dynamics have been investigated by femtosecond time-and angle-resolved …

We review a number of experimental techniques that are beginning to reveal fine details of
the bosonic spectrum α 2 F (Ω) that dominates the interaction between the quasiparticles in …

We review the search for a mediator of high-T c superconductivity focusing on ARPES
experiment. In case of HTSC cuprates, we summarize and discuss a consistent view of …

We have performed numerical studies of the Hubbard-Holstein model in two dimensions
using determinant quantum Monte Carlo (DQMC). Here, we present details of the method …

Using high-resolution angle-resolved photoemission spectroscopy we have studied the
momentum and photon energy dependence of the anomalous high-energy dispersion …
