Unitary quantum evolution for time-dependent quasi-Hermitian systems with non-observable Hamiltonians
Andreas Fring, Miled H. Y. Moussa
It has been argued that it is incompatible to maintain unitary time-evolution for time-dependent non-Hermitian Hamiltonians when the metric operator is explicitly time-dependent. W…
A unifying E2-quasi-exactly solvable model
Andreas Fring
A new non-Hermitian E2-quasi-exactly solvable model is constructed containing two previously known models of this type as limits in one of its three parameters. We identify the opt…
Nonclassicality versus entanglement in a noncommutative space
Sanjib Dey, Andreas Fring, Véronique Hussin
In a setting of noncommutative space with minimal length we confirm the general assertion that the more nonclassical an input state for a beam splitter is, the more entangled its o…
Time-dependent massless Dirac fermions in graphene
Boubakeur Khantoul, Andreas Fring
Using the Lewis-Riesenfeld method of invariants we construct explicit analytical solutions for the massless Dirac equation in 2+1 dimensions describing quasi-particles in graphene.…
