Relativistic hyperbolic motion and its higher order kinematic quantities
Ivan Perez-Roman, Haret C. Rosu
We investigate the kinematics of the motion of an observer with constant proper acceleration (relativistic hyperbolic motion) in 1+1 and 1+3 dimensional Minkowski spacetimes. We pr…
Vanishing Poynting observers and electromagnetic field classification in Kerr and Kerr-Newman spacetimes
H. Vargas-Rodríguez, H. C. Rosu, M. G. Medina-Guevara +2
We consider electromagnetic fields having an angular momentum density in a locally non-rotating reference frame in Schwarzschild, Kerr, and Kerr-Newman spacetimes. The nature of su…
Superfluid Rayleigh-Plesset extension of FLRW cosmology
H. C. Rosu, S. C. Mancas, C. -C. Hsieh
Guided by the analogy with the Rayleigh-Plesset dynamics of multielectron bubbles in superfluid He-4, we consider the cosmological FLRW evolution equation with additional cubic and…
Note on Hawking-Unruh effects in graphene
Pisin Chen, H. C. Rosu
Beltrami-shaped graphene sheets have been recently proposed as analogs of curved spacetimes with Hawking-Unruh effects detected through typical condensed matter measurements involv…
Shifted Riccati Procedure: Application to Conformal Barotropic FRW Cosmologies
Haret C. Rosu, Kira V. Khmelnytskaya
In the case of barotropic FRW cosmologies, the Hubble parameter in conformal time is the solution of a simple Riccati equation of constant coefficients. We consider these cosmologi…
Supersymmetry of FRW barotropic cosmologies
H. C. Rosu, P. Ojeda-May
Barotropic FRW cosmologies are presented from the standpoint of nonrelativistic supersymmetry. First, we reduce the barotropic FRW system of differential equations to simple harmon…
