Approaching the adiabatic infimum of topological pumps on thin-film lithium niobate waveguides
Nature CommunicationsTopological pumps reveal topological insights of adiabatic mode evolution, in which adiabaticity plays a crucial role. However, the adiabatic infimum, i.e., the possible shortest evolution duration of an adiabatic topological pumping process, has ...

A simple analytical model for dark matter halo structure and adiabatic contraction
, 2006 A simple analytical model for describing inner parts of dark matter halo is considered. It is assumed that dark matter density is power-law. The model deals with dark matter distribution function in phase space of adiabatic invariants (radial action and ...

Advanced Materials Interfaces, EarlyView.This study showcases the airbrush method, a novel coating technique for the preparation of thin black paint coatings for infrared camera measurements. Using the method, coatings with an emissivity of 0.95, and as thin as 3 µm can be prepared. The method is affordable, non‐destructive, and can be prepared onto a wide range of substrates while ...

Shortcuts to adiabaticity using flow fields
New Journal of Physics, 2017 A shortcut to adiabaticity is a recipe for generating adiabatic evolution at an arbitrary pace. Shortcuts have been developed for quantum, classical and (most recently) stochastic dynamics. A shortcut might involve a counterdiabatic (CD) Hamiltonian that

Particle creation and particle number in an expanding universe
, 2012 I describe the logical basis of the method that I developed in 1962 and 1963 to define a quantum operator corresponding to the observable particle number of a quantized free scalar field in a spatially-flat isotropically expanding (and/or contracting ...

Defect Formation Preempts Dynamical Symmetry Breaking in Closed Quantum Systems
, 2011 We show that no matter how slowly a quantum-to-classical symmetry breaking process is driven, the adiabatic limit can never be reached in a macroscopic body.
