Second-order linear differential equations associated to a Riccati equation of constant coefficients
H. C. Rosu, O. Cornejo, M. Reyes +1
We present several second-order linear differential equations that are associated to a particular Riccati equation with only one constant parameter in its coefficients through the…
Milne phase for the Coulomb quantum problem related to Riemann's hypothesis
H. C. Rosu, J. M. Moran-Mirabal, M. Planat
We use the Milne phase function in the continuum part of the spectrum of the particular Coulomb problem that has been employed by Bhaduri, Khare, and Law as an equivalent physical…
Ramanujan sums for signal processing of low frequency noise
M. Planat, H. C. Rosu, S. Perrine
An aperiodic (low frequency) spectrum may originate from the error term in the mean value of an arithmetical function such as Möbius function or Mangoldt function, which are coding…
One-parameter Darboux transformations in Thermodynamics
H. C. Rosu
The quantum oscillator thermodynamic actions are the conjugate intensive parameters for the frequency in any frequency changing process. These oscillator actions fulfill simple Ric…
Differential equations extended to superspace
J. Torres, H. C. Rosu
We present a simple SUSY N=2 superspace extension of the differential equations in which the sought solutions are considered to be real superfields but maintaining the common deriv…
