Preservation of atomic coherence in double-well optical lattice in presence of decoherence

TL;DR

This paper proposes a quantum interference method to maintain atomic coherence in a double-well optical lattice despite decoherence effects, by selecting appropriate initial states, demonstrated specifically against spontaneous emission.

Contribution

It introduces a novel quantum interference technique for coherence preservation in optical lattices, focusing on initial state selection to counteract decoherence.

Findings

Coherence can be preserved using quantum interference with proper initial states.

The method effectively mitigates decoherence from spontaneous emission.

Demonstrated in a one-dimensional double-well optical lattice.

Abstract

We present a quantum interference approach to preserve coherence in the external states of an atom trapped in an optical lattice. We show that this is possible by suitably choosing the initial state of the atom. We demonstrate this in context of decoherence due to spontaneous emission in an one-dimensional optical double-well lattice.
