Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

Quantum adiabatic processes—that keep constant the populations in the instantaneous
eigenbasis of a time-dependent Hamiltonian—are very useful to prepare and manipulate …

Adiabatic processes are ubiquitous in physics and engineering. A drawback of such
processes is that they tend to be slow, either in time–for atomic systems, for example–or in …

Shortcuts to adiabaticity in various quantum systems have attracted much attention with their
wide applications in quantum information processing and quantum control. In this paper, we …

We propose large bandwidth and high fabrication-tolerance mode-order converters on the
silicon-on-insulator platform based on novel compact tapers structures. Each of the …

Non-Hermitian systems host unconventional physical effects that be used to design new
optical devices. We study a non-Hermitian system consisting of 1D planar optical …

Sped-up protocols that drive a system quickly to the same populations that can be reached
by a slow adiabatic process may involve Hamiltonian terms which are difficult to realize. We …

Shortcut to adiabatic passage (STAP), initially proposed to accelerate adiabatic quantum-
state transfer, has been widely explored and applied in quantum optics and integrated …

A short and broadband silicon asymmetric Y-junction two-mode (de) multiplexer is proposed
and simulated. An adiabaticity parameter suitable for high index-contrast silicon waveguides …

In recent years, the concept of shortcuts to adiabaticity (STA), originally developed for
speeding up slow adiabatic state evolution in quantum systems, has found numerous …
