# Enhancement of Local Pairing Correlations in Periodically Driven Mott Insulators

## TL;DR

This paper explores how periodic driving and dissipation in Mott insulators can enhance local pairing correlations and potentially induce long-range superconducting order, including eta-pairing, in non-equilibrium steady states.

## Contribution

It introduces a model showing that drive and dissipation can significantly increase doublon excitations and promote long-range superconducting correlations in Mott insulators.

## Key findings

- Large doublon excitations in non-equilibrium steady states
- Enhanced local pairing correlations due to periodic drive
- Potential realization of eta-pairing phase in driven systems

## Abstract

We investigate a model for a Mott insulator in presence of a time-periodic modulated interaction and a coupling to a thermal reservoir. The combination of drive and dissipation leads to non-equilibrium steady states with a large number of doublon excitations, well above the maximum thermal-equilibrium value. We interpret this effect as an enhancement of local pairing correlations, providing analytical arguments based on a Floquet Hamiltonian. Remarkably, this Hamiltonian shows a tendency to develop long-range staggered superconducting correlations. This suggests the possibility of realizing the elusive eta-pairing phase in driven-dissipative Mott Insulators.
