Theory of Photon Subtraction for Two-Mode Entangled Light Beams
Oscar Rosas-Ortiz, Kevin Zelaya
Photon subtraction is useful to produce nonclassical states of light addressed to applications in photonic quantum technologies. After a very accelerated development, this techniqu…
Exact solutions for time-dependent non-Hermitian oscillators: classical and quantum pictures
Kevin Zelaya, Oscar Rosas-Ortiz
We associate the stationary harmonic oscillator with time-dependent systems exhibiting non-Hermiticity by means of point transformations. The new systems are exactly solvable, with…
Constructing Squeezed States of Light with Associated Hermite Polynomials
Kevin Zelaya, Véronique Hussin, Oscar Rosas-Ortiz
A new class of states of light is introduced that is complementary to the well-known squeezed states. The construction is based on the general solution of the three-term recurrence…
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 Time-Dependent Oscillator-Like Potentials Generated by Darboux Transformations
Kevin Zelaya, Oscar Rosas-Ortiz
The stationary Schroedinger equation of the harmonic oscillator is deformed by a Darboux transformation to construct time-dependent potentials with the oscillator profile. The Darb…
