The material realization of charge-4e/6e superconductivity (SC) is a big challenge. Here, we
propose to realize charge-4e SC in maximally-twisted homobilayers, such as 45∘-twisted …

Cavity control of quantum matter may offer new ways to study and manipulate many-body
systems. A particularly appealing idea is to use cavities to enhance superconductivity …

A number of experiments have evidenced signatures of enhanced superconducting
correlations after photoexcitation. Initially, these experiments were interpreted as resulting …

Electronically ordered states that break multiple symmetries can melt in multiple stages,
similarly to liquid crystals. In a partially melted phase, known as vestigial phase, a bilinear …

We propose a general mechanism to realize nematic superconductivity (SC) and reveal its
exotic vestigial phases in the quasicrystal (QC). Starting from a Penrose-Hubbard model, our …

The collective mode spectrum of a symmetry-breaking state, such as a superconductor,
provides crucial insight into the nature of the order parameter. In this work, we study two …

We show that in electron-hole bilayers with excitonic orders arising from conduction and
valence bands formed by atomic orbitals that have different parities, nonzero interlayer …

Stacking and twisting graphene layers allows to create and control a two-dimensional
electron liquid with strong correlations. Experiments indicate that these systems exhibit …

Motivated by recent experiments on twisted junctions of cuprate superconductors (SCs), it
was proposed [Yuan, Inhomogeneity-induced time-reversal symmetry breaking in cuprate …

We apply a wavefunction approach to study the charge 4$ e $ superconductor. The
wavefunction takes a similar structure to the BCS wavefunction for charge 2$ e …
