Uncertainty inequalities in a non-Hermitian scenario
Yanet Alvarez, Mariela Portesi, Romina Ramirez +1
We investigate uncertainty relations for quantum observables evolving under non-Hermitian Hamiltonians, with particular emphasis on the role of metric operators. By constructing ap…
A Pseudo-Hermitian Hybrid Model at Finite Temperature: The Role of the Exceptional Points
Ignacio Fushimi, Marta Reboiro
We study a hybrid system formed by an ensemble of colour nitrogen-vacancy centres in diamond interacting with a superconducting flux-qubit at finite temperature. The presence of im…
Non-standard quantum algebras and infinite-dimensional PT-symmetric systems
Ángel Ballesteros, Romina Ramírez, Marta Reboiro
In this work, we introduce a PT-symmetric infinite-dimensional representation of the Uz(sl(2,R)) Hopf algebra, and we analyse a multiparametric family of Hamiltonians constructed f…
