Application of the Eckart frame to soft matter: rotation of star polymers under shear flow

We present the first ever application of the Eckart co-rotating frame to a soft matter system where molecular vibrations and rotation are coupled.

Neutrino interaction with background matter in a non-inertial frame

We study Dirac neutrinos propagating in rotating background matter. First we derive the Dirac equation for a single massive neutrino in the non-inertial frame, where matter is at rest. This equation is written in the effective curved spacetime corresponding to the co-rotating frame. We find the exact solution of the Dirac equation. The neutrino energy levels for ultrarelativistic particles are obtained. Then we discuss several neutrino mass eigenstates, with a nonzero mixing between them, interacting with rotating background matter. We derive the effective Schrödinger equation governing neutrino flavor oscillations in rotating matter. The new resonance condition for neutrino oscillations is obtained. We also examine the correction to the resonance condition caused by the matter rotation.

Rotational Pertubation of Masive Scalar Field Universes

In this course of presentation, we will consider the rotational perturbation of the Robertson-Walker universe will be examined in order to substantiate the possibility of the existence of Massive scalar field. We will study, the exact solutions for metric rotation Ω( r,t ) and the matter rotation w ( r,t ) under different conditions, and also study their nature and role from different angles.

DIRECTED FLOW AS AN EFFECT OF TRANSIENT MATTER ROTATION IN HADRON AND NUCLEUS COLLISIONS

We discuss directed flow v1, an observable introduced for the description of nucleus collisions. We consider its possible origin in hadronic reactions as a result of rotation of the transient matter and trace the analogy with nucleus collisions.
