Magic-angle twisted trilayer graphene (MATTG) has emerged as a moiré material that
exhibits strong electronic correlations and unconventional superconductivity,. However …

The existence of electronic symmetry breaking in the underdoped cuprates and its
disappearance with increased hole density p are now widely reported. However, the relation …

The phase diagram for a general model for cuprates is derived in a mean-field
approximation. A phase-violating time reversal without breaking translational symmetry is …

We review recent experimental and theoretical results on the interaction between single-
particle excitations and collective spin excitations in the superconducting state of high-Tc …

We review the field of high temperature cuprate superconductors, with emphasis on the
nature of their electronic properties. After a general overview of experiment and theory, we …

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

We explore manifestations of electron-phonon coupling on the electron spectral function for
two phonon modes in the cuprates exhibiting strong renormalizations with temperature and …

Identifying the mechanism of superconductivity in the high-temperature cuprate
superconductors is one of the major outstanding problems in physics. We report local …

Coulomb interactions between the carriers may provide the mechanism for enhanced
unconventional superconductivity in the copper oxides. However, they simultaneously cause …

We present our angle-resolved photoemission spectroscopy (ARPES) studies of the cuprate
high-temperature superconductors; these studies elucidate the relation between …
