    • A note on Verhulst's logistic equation and related logistic maps 

      Gutiérrez, M. Ranferí; Reyes, Marco A.; Rosu Barbus, Haret-Codratian (2010)
      "We consider the Verhulst logistic equation and a couple of forms of the corresponding logistic maps. For the case of the logistic equation we show that using the general Riccati solution only changes the initial conditions ...

    • An amplitude-phase (Ermako-Lewis) approach for the Jackiw-Pi model of bilayer graphene 

      Khmelnytskaya, Kira V.; Rosu Barbus, Haret-Codratian (2009)
      "In the context of bilayer graphene we use the simple gauge model of Jackiw and Pi to construct its numerical solutions in powers of the bias poten-tial V according to a general scheme due to Kravchenko. Next, using this ...

    • Cerium-doped β-Ni(OH)2 hexagon nanosheets: an effective photocatalyst for the degradation of the emerging water pollutant, naproxen 

      Regmi, Chhabilal; Maya Flores, Etel; Lee, Soo Wohn; Rodríguez González, Vicente (2018)
      "Nickel hydroxide β–Ni(OH)2 hexagonal nanosheets were synthetized via a hydrothermal exfoliation process. The practical microwave-assisted hydrothermal method facilitated obtaining layered nickel 3D nanoplates with cerium ...

    • Classical harmonic oscillator with Dirac-like parameters and possible applications 

      Rosu Barbus, Haret-Codratian; Cornejo Pérez, Octavio; López Sandoval, Román (2004)
      "We obtain a class of parametric oscillation modes that we call K-modes with damping and absorption that are connected to the classical harmonic oscillator modes through the “supersymmetric” one-dimensional matrix procedure ...

    • Gravitational bouncing of a quantum ball: Room for Airy's function Bi 

      Rosu Barbus, Haret-Codratian (2002)
      "I apply (i) a classical version of the Ermakov-Lewis procedure and (ii) the strictly isospectral supersymmetric approach to the Schrodinger free fall of the bouncing ball type. In both cases, the Airy function Bi, which ...

    • Magnetic structure and magneto-volume anomalies in Er(2)Fe(17) compound 

      Álvarez Alonso, Pablo; Gorria, Pedro; Marcos, Jorge Sánchez; Puente Orench, Inés; Rodríguez Velamazán, José Alberto; Cuello, Gabriel J.; Sánchez Llamazares, José Luis; Blanco Rodríguez, Jesús Angel (2011)
      "Neutron powder diffraction shows that the intermetallic Er(2)Fe(17) compound with hexagonal crystal structure has a ferrimagnetic ground state (T(C) = 303 K). At T = 5 K the magnetic moments of Fe sublattice (mu similar ...

    • Multifractal properties of elementary cellular automata in a discrete wavelet approach of MF-DFA 

      Murguía, José; Pérez Terrazas, Jaime Enrique; Rosu Barbus, Haret-Codratian (2009)
      "In 2005, Nagler and Claussen (Phys. Rev. E 71, 067103 (2005)) investigated the time series of the elementary cellular automata (ECA) for possible (multi)fractal behavior. They eliminated the polynomial background atb ...

    • Mutually unbiased bases and finite projective planes 

      Saniga, Metod; Planat, Michel; Rosu Barbus, Haret-Codratian (2004)
      "It is conjectured that the question of the existence of a set of d+1 mutually unbiased bases in a d-dimensional Hilbert space if d differs from a power of a prime number is intimately linked with the problem of whether ...

    • Nonsingular parametric oscillators Darboux-related to the classical harmonic oscillator

      "Interesting nonsingular parametric oscillators which are Darboux related to the classical harmonic oscillator and have periodic dissipative/gain features are identi?ed through a modi?ed factorization method. The same ...

    • One-parameter Darboux-transformed quantum actions in thermodynamics 

      Rosu Barbus, Haret-Codratian; Aceves de la Cruz, Fermín (2002)
      "We use nonrelativistic supersymmetry, mainly Darboux transformations of the general (one-parameter) type, for the quantum oscillator thermodynamic actions. Interesting Darboux generalizations of the fundamental Planck and ...

    • Riccati-parameter solutions of nonlinear second-order ODEs 

      Reyes, Marco A.; Rosu Barbus, Haret-Codratian (2008)
      "It has been proven by Rosu and Cornejo-Pérez [1, 2] that for some nonlinear second-order ODEs it is a very simple task to find one particular solution once the nonlinear equation is factorized with the use of two first-order ...
