Abstract In this paper we analyze the expectation value of field squared and energy–momentum tensor associated with a massive charged scalar quantum nonzero chemical potential propagating in high-dimensional compactified cosmic string spacetime thermal equilibrium at finite temperature T . Moreover, assume that interacts very thin magnetic flux running along core idealized string, enclosed by c...

A unification of the gravitational with the electromagnetic interaction within a classical framework is proposed. It is based on a Fs-geometry, with x^ — qjm. The sole source term is mechanical stress energy, positioned along X5. The trajectories of testbodies are placed in V4 (xo = const)-slices. The final field equation couples a geometric G-tensor to mechanical stress energy, its momentum wi...

Fresnel's theory of the evanescent wave in total reflection entails that the propagation vector k and the momentum quanta hk have an imaginary component and, thus, a projection on the reflecting plane that is larger (in units such that c = 1) than the angular frequency ~o and the energy quanta ho). We discuss the 'tachyon properties' of these energy-momentum quanta and propose an experimental t...

To understand the coupling behavior of the spinor with spacetime, the explicit form of the energy-momentum tensor of the spinor in curved spacetime is important. This problem seems to be overlooked for a long time. In this paper we derive the explicit form of energy momentum tensors and display some equivalent but simple forms of the covariant derivatives for both the Weyl spinor and the Dirac ...

From the deep-inelastic momentum sum rule and the trace anomaly of the energy-momentum tensor, I derive a separation of the nucleon mass into the contributions of the quark and gluon kinetic and potential energies, the quark masses, and the trace anomaly.

We derive maps relating the currents and energy-momentum tensors in noncommutative (NC) gauge theories with their commutative equivalents. Some uses of these maps are discussed. Especially, in NC electrodynamics, we obtain a generalization of the Lorentz force law. Also, the same map for anomalous currents relates the Adler-BellJackiw type NC covariant anomaly with the standard commutative-theo...

We use the fluid-gravity correspondence to compute subextensive corrections, proportional to the shear tensor, to the energy-momentum tensor of fluids on threespheres. The dual configurations we consider are charged black hole solutions of N = 2 gauged supergravity theories in five dimensions.

The recently derived current algebra of classical non-linear sigma models on arbitrary Riemannian manifolds is extended to include the energy-momentum tensor. It is found that in two dimensions the energy-momentum tensor θμν , the Noether current jμ associated with the global symmetry of the theory and the composite field j appearing as the coefficient of the Schwinger term in the current algeb...
