Fast and robust magnon transport in a spin chain
Anthony Kiely, Steve Campbell
A protocol for fast and robust magnon transport in a one-dimensional spin chain is devised. Employing an approximate mapping between the chain and a single harmonically trapped par…
Quantum-optical implementation of non-Hermitian potentials for asymmetric scattering
Andreas Ruschhaupt, Anthony Kiely, Miguel Ángel Simón +1
Non-Hermitian, one-dimensional potentials which are also non-local, allow for scattering asymmetries, namely, asymmetric transmission or reflection responses to the incidence of a…
Quantum Control via Enhanced Shortcuts to Adiabaticity
Chris Whitty, Anthony Kiely, Andreas Ruschhaupt
Fast and robust quantum control protocols are often based on an idealised approximate description of the relevant quantum system. While this may provide a performance which is clos…
Energetic cost of quantum control protocols
Obinna Abah, Ricardo Puebla, Anthony Kiely +3
We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic…
Shortcuts to adiabaticity: concepts, methods, and applications
D. Guéry-Odelin, A. Ruschhaupt, A. Kiely +3
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 an…
-matrix pole symmetries for non-Hermitian scattering Hamiltonians
M. A. Simón, A. Buendía, A. Kiely +2
The complex eigenvalues of some non-Hermitian Hamiltonians, e.g. parity-time symmetric Hamiltonians, come in complex-conjugate pairs. We show that for non-Hermitian scattering Hami…
