Abstract

Abstract:

In recent years, shortcuts to adiabaticity (STA) had been proposed to accelerate slow adiabatic processes. In this study, based on the quantum-optical analogy, the rapid compression of solitons in nonlocal nonlinear media was investigated by combining the variational method and inverse engineering of STA technology. A comparison with the results of adiabatic compression showed that nonlocality had an inhibitory effect on nonlinearity. In addition, the greater the degree of nonlocality, the longer was the propagation distance required for adiabatic compression, thus making it more difficult to compress solitons in nonlocal media using adiabatic protocols. However, it was found that the STA protocol could still effectively compress solitons over a very short distance, thus showing the advantages of the STA protocol.

Key words: shortcut to adiabaticity (STA), soliton compression, nonlocal nonlinear media
