Overdoped high-temperature cuprate superconductors have often been understood within
the standard BCS framework of superconductivity. However, measurements in a variety of …

The Fermi surface symmetric mass generation (SMG) is an intrinsically interaction-driven
mechanism that opens an excitation gap on the Fermi surface without invoking symmetry …

A possible explanation for the existence of the cuprate “pseudogap” state is that it is a d-
wave superconductor without quantum phase rigidity. Transport and thermodynamic studies …

We study the phase fluctuations in the normal state of generic two-dimensional
superconducting systems with s-wave pairing. The effect of phase fluctuations of the pairing …

One of the key motivations for the development of atomically resolved spectroscopic imaging
scanning tunneling microscopy (SI-STM) has been to probe the electronic structure of …

Since their discovery, it has been suggested that pairing in pnictides can be mediated by
spin fluctuations between hole and electron bands. In this view, multiband superconductivity …

We report measurements of the ab-plane superfluid density ns (magnetic penetration depth
λ) of heavily underdoped films of YBa 2 Cu 3 O 6+ x, with TC's from 6 to 50 K. We find the …

We apply the static auxiliary field Monte Carlo approach to study phase correlations of the
pairing fields in a model with spin-singlet pairing interaction. We find that the short-and long …

Two-dimensional hard core bosons suffer strong scattering in the high-temperature resistive
state at half filling. The dynamical conductivity σ (ω) is calculated using nonperturbative tools …

We investigate a bilayer honeycomb lattice model of spin-1/2 fermions at half-filling with
local Heisenberg coupling of fermion spins across the two layers. Using variational Monte …
