Superfluid Rayleigh–Plesset extension of FLRW cosmology
Rosu Barbus, Haret-Codratian; Mancas, Stefan C; Hsieh, Chun-Chung (Elsevier, 2021)"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 sixth powers of the inverse of the scale ... -
Traveling wave solutions for wave equations with two exponential nonlinearities
Mancas, Stefan C; Rosu Barbus, Haret-Codratian; Pérez Maldonado, Maximino (Walter de Gruyter GmbH, 2018)"We use a simple method that leads to the integrals involved in obtaining the travelling-wave solutions of wave equations with one and two exponential nonlinearities. When the constant term in the integrand is zero, implicit ... -
Two integrable classes of Emden-Fowler equations with applications in astrophysics and cosmology
Mancas, Stefan C; Rosu Barbus, Haret-Codratian (Walter de Gruyter GmbH, 2018)"We show that some Emden–Fowler (EF) equations encountered in astrophysics and cosmology belong to two EF integrable classes of the type d2z/dχ2=Aχ−λ−2zn for λ=(n−1)/2 (class 1), and λ=n+1 (class 2). We find their corresponding ...
