    • Linearised coherent states for non-rational SUSY extensions of the harmonic oscillator 

      Autor: Contreras-Astorga, Alonso; Fernández C., David J.; Muro-Cabral, César
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      In this work, we derive two equivalent non-rational extensions of the quantum harmonic oscillator using two different supersymmetric transformations. For these extensions, we built ladder operators as the product of the ...

    • Photonic graphene under strain with position-dependent gain and loss 

      Autor: Castillo-Celeita, Miguel; Contreras-Astorga, Alonso; Fernández C., David J.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      We work with photonic graphene lattices under strain with gain and loss, modeled by the Dirac equation with an imaginary mass term. To construct such Hamiltonians and their solutions, we use the free-particle Dirac equation ...
