Speeding up particle slowing using shortcuts to adiabaticity

Scaling-Up Quantum Heat Engines Efficiently via Shortcuts to Adiabaticity

The finite-time operation of a quantum heat engine that uses a single particle as a working medium generally increases the output power at the expense of inducing friction that lowers the cycle efficiency. We propose to scale up a quantum heat engine utilizing a many-particle working medium in combination with the use of shortcuts to adiabaticity to boost the nonadiabatic performance by elimina...

Shortcuts to adiabaticity in a time-dependent box

A method is proposed to drive an ultrafast non-adiabatic dynamics of an ultracold gas trapped in a time-dependent box potential. The resulting state is free from spurious excitations associated with the breakdown of adiabaticity, and preserves the quantum correlations of the initial state up to a scaling factor. The process relies on the existence of an adiabatic invariant and the inversion of ...

Speeding-Up Color FIC Using

In this paper, speeding-up fractal color image compression technique based on zero-mean method by adding symmetry predictor to reduce the number of isometric trails from 8 to one trail. The first order centralized moments are used to index each domain and range blocks onto one of eight possible isometric states. At each range domain the indices of both domain and range blocks are passed through...
