  Title Dual wavefunctions in two-dimensional quantum mechanics Type
  Year 2020 Publication Physics Letters A Abbreviated Journal Phys. Lett. A  
  Volume 384 Issue 13 Pages 5 pp  
  Keywords (up) Schrodinger equation; Dual solution; Bohm potential; Two-dimensions; Optics  
  Abstract It is shown that the Schrodinger equation for a large family of pairs of two-dimensional quantum potentials possess wavefunctions for which the amplitude and the phase are interchangeable, producing two different solutions which are dual to each other. This is a property of solutions with vanishing Bohm potential. These solutions can be extended to three-dimensional systems. We explicitly calculate dual solutions for physical systems, such as the repulsive harmonic oscillator and the two-dimensional hydrogen atom. These dual wavefunctions are also solutions of an analogue optical system in the eikonal limit. In this case, the potential is related to the refractive index, allowing the study of this two-dimensional dual wavefunction solutions with an optical (analogue) system. (C) 2020 Elsevier B.V.

  Title A new approach to solve the one-dimensional Schrodinger equation using a wavefunction potential Type
  Year 2020 Publication Physics Letters A Abbreviated Journal Phys. Lett. A  
  Volume 384 Issue 36 Pages 7 pp  
  Keywords (up) Schrodinger equation; New exact solutions; Accelerating wavepackets; Bohm potential  
  Abstract A new approach to find exact solutions to one-dimensional quantum mechanical systems is devised. The scheme is based on the introduction of a potential function for the wavefunction, and the equation it satisfies. We recover known solutions as well as to get new ones for both free and interacting particles with wavefunctions having vanishing and non-vanishing Bohm potentials. For most of the potentials, no solutions to the Schrodinger equation produce a vanishing Bohm potential. A (large but) restricted family of potentials allows the existence of particular solutions for which the Bohm potential vanishes. This family of potentials is determined, and several examples are presented. It is shown that some quantum, such as accelerated Airy wavefunctions, are due to the presence of non-vanishing Bohm potentials. New examples of this kind are found and discussed.

  Title Magnetic field seed generation in plasmas around charged and rotating black holes Type
  Year 2014 Publication Physica Scripta Abbreviated Journal Phys. Scr.  
  Volume 89 Issue 8 Pages 7 pp  
  Keywords (up) seed magnetic field; general relativistic drive; Kerr metric  
  Abstract Previous work by the authors introduced the possibility of generating seed magnetic fields by spacetime curvature and applied it in the vicinity of a Schwarzschild black hole. It was pointed out that it would be worthwhile to consider the effect in other background geometries and particularly in the vicinity of a rotating black hole, which is generically to be expected, astrophysically. In this paper that suggestion is followed up and we calculate generated magnetic field seed due to Reissner-Nordstrom and Kerr spacetimes. The conditions for the drive for the seed of a magnetic field is obtained for charged black holes, finding that in the horizon the drive vanishes. Also, the psi N-force produced by the Kerr black hole is obtained and its relation with the magnetic field seed is discussed, producing a more effective drive.

  Title Spinning particles coupled to gravity and the validity of the universality of free fall Type
  Year 2017 Publication Classical And Quantum Gravity Abbreviated Journal Class. Quantum Gravity  
  Volume 34 Issue 11 Pages 8 pp  
  Keywords (up) spin-gravity coupling; spinning massive particle; Lagrangian description  
  Abstract Recent experimental work has determined that free falling Rb-87 atoms on Earth, with vertically aligned spins, follow geodesics, thus apparently ruling out spin-gravitation interactions. It is showed that while some spinning matter models coupled to gravitation referenced to in that work seem to be ruled out by the experiment, those same experimental results confirm theoretical results derived from a Lagrangian description of spinning particles coupled to gravity constructed over forty years ago. A proposal to carry out (similar but) different experiments which will help to test the validity of the universality of free fall as opposed to the correctness of the aforementioned Lagrangian theory, is presented.

  Volume 96 Issue 12 Pages 125218  
  Keywords (up) time domain super-symmetry; time dependent harmonic oscillator; Bohm potential; Ermakov-lewis invariant  
  Abstract We show that the time-dependent harmonic oscillator has a repulsive or inverted oscillator as a time domain SUSY-like partner. Examples of several kinds of super-symmetrical time dependent frequency systems are presented.

  Title Quantum particles that behave as free classical particles Type
  Year 2020 Publication PHYSICAL REVIEW A Abbreviated Journal Phys. Rev. A  
  Volume 102 Issue 5 Pages 052211  
  Keywords (up) Wave; Generation  
  Abstract The existence of nonvanishing Bohm potentials, in the Madelung-Bohm version of the Schrödinger equation, allows for the construction of particular solutions for states of quantum particles interacting with nontrivial external potentials that propagate as free classical particles. Such solutions are constructed with phases which satisfy the classical Hamilton-Jacobi for free particles and whose probability densities propagate with constant velocity, as free classical particles do.
