Planar Dirac equation with radial contact potentials
J. T. Lunardi, S. Salamanca, J. Negro +1
We investigate the planar Dirac equation with the most general time-independent contact (singular) potential supported on a circumference. Taking advantage of the radial symmetry,…
SUSY hierarchies of Jaynes-Cummings Hamiltonians with different detuning parameters
Ä°smail Burak AteÅ, Åengül Kuru, Javier Negro
The aim of this work is to show how supersymmetric (SUSY) quantum mechanics can be applied to the Jaynes-Cummings (JC) Hamiltonian of quantum optics. These SUSY transformations con…
Demkov-Fradkin tensor for curved harmonic oscillators
Åengül Kuru, Javier Negro, Sergio Salamanca
In this work, we obtain the Demkov-Fradkin tensor of symmetries for the quantum curved harmonic oscillator in a space with constant curvature given by a parameter . In order to…
Electric and magnetic waveguides in graphene: quantum and classical
David Barranco, Åengül Kuru, Javier Negro
Electric and magnetic waveguides are considered in planar Dirac materials like graphene as well as their classical version for relativistic particles of zero mass and electric char…
