Special Issue Information
Dear Colleagues,
Driving a system by slowly changing the control parameters guarantees, ideally, no excitations from the initial to the final setting, and the same final energies independent of the exact (smooth) trajectory of the parameters. Two main drawbacks of this “adiabatic” approach are the length of time it takes and the fact that non-ideal, noisy conditions may spoil the intended outcome. Even so, adiabatic methods are ubiquitous in physics, chemistry, and engineering.
Shortcuts to adiabaticity (STA) are a set of techniques to get the same results as the adiabatic methods in a short time, allowing for some transient excitations. The main approaches are based on invariants, fast-forward or counterdiabatic driving, inverse engineering, and local adiabatic methods, possibly hybridized with optimal control theory, perturbative, iterative, Lie-algebraic, and variational methods. Most of these approaches produce families of parameter paths, which can be used to optimize resilience with respect to noise and perturbations. Quantum physics has been the main application field, since the delicate quantum coherence is easily degraded in slow manipulations, but preserving it is essential to develop new quantum technologies. A further motivation is the possibility to produce microscopic engines or refrigerators that are both efficient and powerful. Other fields where STA are being applied include optics, to produce more compact devices; classical or stochastic mechanics; physical chemistry; and engineering.
Shortcuts play a very practical role, but also imply fundamental questions such as determining the trade-off relations and limits for process time, energy consumption, or information needed. This Special Issue will reflect the current, rich scenario of methods and applications of shortcuts to adiabaticity.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
