On the construction of non-Hermitian Hamiltonians with all-real spectra through supersymmetric algorithms
Kevin Zelaya, Sara Cruz y Cruz, Oscar Rosas-Ortiz
The energy spectra of two different quantum systems are paired through supersymmetric algorithms. One of the systems is Hermitian and the other is characterized by a complex-valued…
Coherent states for exactly solvable time-dependent oscillators generated by Darboux transformations
Sara Cruz y Cruz, Ruben Razo, Oscar Rosas-Ortiz +1
The Darboux method is commonly used in the coordinate variable to produce new exactly solvable (stationary) potentials in quantum mechanics. In this work we follow a variation intr…
Exactly solvable one-qubit driving fields generated via non-linear equations
Marco Enriquez, Sara Cruz y Cruz
Using the Hubbard representation for we write the time-evolution operator of a two-level system in the disentangled form. This allows us to map the corresponding dynamical…
Negative time delay for wave reflection from a one-dimensional semi-harmonic well
Oscar Rosas-Ortiz, Sara Cruz y Cruz, Nicolas Fernandez-Garcia
It is reported that the phase time of particles which are reflected by a one-dimensional semi-harmonic well includes a time delay term which is negative for definite intervals of t…
A Primer on Resonances in Quantum Mechanics
O. Rosas-Ortiz, N. Fernandez-Garcia, Sara Cruz y Cruz
After a pedagogical introduction to the concept of resonance in classical and quantum mechanics, some interesting applications are discussed. The subject includes resonances occurr…
