Time scaling and quantum speed limit in non-Hermitian Hamiltonians
F. Impens, F. M. D'Angelis, F. A. Pinheiro +1
We report on a time scaling technique to enhance the performances of quantum protocols in non-Hermitian systems. The considered time scaling involves no extra-couplings and yields…
Fast and robust quantum state transfer in a topological Su-Schrieffer-Heeger chain with Next-to-Nearest-Neighbour interactions
Felippo M. D'Angelis, Felipe A. Pinheiro, David Guéry-Odelin +2
We suggest a method for fast and robust quantum-state transfer in a Su-Schrieffer-Heeger (SSH) chain, which exploits the use of next-to-nearest-neighbour (NNN) interactions. The pr…
Tuning quantum reflection in graphene with an external magnetic field
Marcius Silvestre, Tarik P. Cysne, Daniela Szilard +2
We theoretically demonstrate that an external magnetic field can be used to control quantum reflection of matter waves in graphene due to its extraordinary magneto-optical properti…
Decoherence and collective effects in critical media
F. M. D Angelis, F. A. Pinheiro, F. Impens
We investigate the influence of critical phenomena on two distinct physical processes: the center-of-mass decoherence of a single emitter, and the collective radiation of two emitt…
Characterizing critical exponents via Purcell effect
M. B. Silva-Neto, D. Szilard, F. S. S. Rosa +2
We investigate the role of phase transitions into the spontaneous emission rate of quantum emitters embedded in a critical medium. Using a Landau-Ginzburg approach, we find that, i…
