## Manifestations of spin-orbit coupling in a cuprate superconductor

Exciting new work on Bi2212 shows the presence of non-trivial spin-orbit coupling effects as seen in spin resolved ARPES data [Gotlieb et al., Science, 362, 1271-1275 (2018)]. Motivated by these observations we consider how the picture of spin-orbit …

## Optical Enhancement of Superconductivity via Targeted Destruction of Charge Density Waves

It has been experimentally established that the occurrence of charge density waves is a common feature of various under-doped cuprate superconducting compounds. The observed states, which are often found in the form of bond density waves (BDW), often …

## Cavity Higgs-Polaritons

Motivated by the dramatic success of realizing cavity exciton-polariton condensation in experiment we consider the formation of polaritons from cavity photons and the amplitude or Higgs mode of a superconductor. Enabled by the recently predicted and …

## Cavity Quantum Eliashberg Enhancement of Superconductivity

Driving a conventional superconductor with an appropriately tuned classical electromagnetic field can lead to an enhancement of superconductivity via a redistribution of the quasiparticles into a more favorable nonequilibrium distribution—a …

## Competing orders in cuprates

Investigation of the interplay between superconductivity and charge ordered phases in the cuprate family of high $T_c$ superconductors.

## Phase pinning and interlayer effects on competing orders in cuprates

Over the past few years, several exciting experiments in the cuprates have seen evidence of a transient superconducting state upon optical excitation polarized along the c-axis [R. Mankowsky et al., Nature 516, 71 (2014)]. The competition between …

## Properties of superconductors coupled to photonic cavities

We study the phenomena which can arise when cavity photons are strongly coupled to superconductors.

## Cavity superconductor-polaritons

Following the recent success of realizing exciton-polariton condensates in cavities, we examine the hybridization of cavity photons with the closest analog of excitons within a superconductor, states called Bardasis-Schrieffer (BS) modes. Though BS …

## Hybridization of Higgs Modes in a Bond-Density-Wave State in Cuprates

We study the mixing of Higgs modes in a state with coexistent bond-density-wave order and superconductivity.
