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…
Trapped-ion Fock state preparation by potential deformation
M. A. Simón, M. Palmero, S. Martínez-Garaot +1
We propose protocols to prepare highly excited energy eigenstates of a trapped ion in a harmonic trap which do not require laser pulses to induce transitions among internal levels.…
Towards generation of cat states in trapped ions set-ups via FAQUAD protocols and dynamical decoupling
Mikel Palmero, Miguel Ángel Simón, Dario Poletti
The high fidelity generation of strongly entangled states of many particles, such as cat states, is a particularly demanding challenge. One approach is to drive the system, within…
-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…
Asymmetric scattering by non-hermitian potentials
A. Ruschhaupt, T. Dowdall, M. A. Simón +1
The scattering of quantum particles by non-hermitian (generally nonlocal) potentials in one dimension may result in asymmetric transmission and/or reflection from left and right in…
