We study the effect of the correlated hopping term and the intersite Coulomb interaction term
on principal features of the d-wave superconducting (SC) state, in both the electron-and hole …

We study the coexistence of pair-(PDW) and charge-density-wave (CDW) states within the
single-band tJU and Hubbard models of d-wave superconductivity and discuss our results in …

Interplay of Pomeranchuk instability (spontaneous symmetry breaking of the Fermi surface)
and d-wave superconductivity is studied for the repulsive Hubbard model on the square …

We present a T= 0K renormalization group (RG) phase diagram for the hole-doped 2D
Hubbard model on the square lattice. The RG method employed is nonperturbative in …

In this article, we investigate the existence of nematic-superconducting states in the
Ginzburg–Landau regime, both analytically and numerically. From the configurations …

The cuprate superconductors are characterised by numerous ordering tendencies, with the
electronically nematic order being the most distinct form of order. Here the intertwinement of …

This article addresses both the existence and properties of non-trivial solutions for a system
of coupled Ginzburg-Landau equations derived from nematic-superconducting models. Its …

The intra-unit-cell nematic phase is studied within the three-band Emery model of the
cuprates by using the diagrammatic expansion of the Gutzwiller wave function (DE-GWF) …

We analyze the effect of intersite interactions on the stability of the coexisting
superconducting-nematic phase (SC+ N) within the extended Hubbard and t–J–U models …

Experiments carried over the last years on the underdoped cuprates have revealed a variety
of symmetry-breaking phenomena in the pseudogap state. Charge-density waves, breaking …
