Self-Propelled Collective Motion with Multiplicative Scalar Noise
Fatemeh Haghsheno, Mohammad Mehrafarin
The emergence of order from initial disordered movement in self-propelled collective motion is an instance of nonequilibrium phase transition, which is known to be first order in t…
Unification based on the mysterious cubic-structure grouping of quarks and leptons
Mohammad Mehrafarin
We present a unification model based on the well-known but mysterious cubic-structure grouping of quarks and leptons that suggests an underlying symmetry connection deemed explaina…
Spin Hall effect of light in inhomogeneous axion field
Mansoureh Hoseini, Mohammad Mehrafarin
We study the spin transport of light in weakly inhomogeneous axion field in a flat Robertson-Walker universe and derive the spin Hall effect for circularly polarized rays. Regardin…
Cosmological Birefringence and the Geometric Phase of Photons
Mansoureh Hoseini, Mohammad Mehrafarin
Regarding axion electrodynamics in the background flat FRW universe, we show that cosmological birefringence arises from an adiabatic noncyclic geometric phase that appears in the…
Berry phase of primordial scalar and tensor perturbations in single-field inflationary models
Hamideh Balajani, Mohammad Mehrafarin
In the framework of the single-field slow-roll inflation, we derive the Hamiltonian of the linear primordial scalar and tensor perturbations in the form of time-dependent harmonic…
Dirac phase and replicating adiabaticity in isotropically moving wall confinement
Mohammad Mehrafarin, Reza Torabi
Geometric phase in the wave function is important with regard to quantum non-locality and adiabatic evolution. We study the confinement of a particle by three-dimensional isotropic…
