By treating magnetic charge as a gauge symmetry through the introduction of a " magnetic " pseudo four-vector potential, it is shown that it is possible, using the 't Hooft-Polyakov construction, to… (More)

We present a phenomenological model for baryogenesis based on particle creation in the Friedman– Robertson–Walker (FRW) space-time. This study is a continuation of our proposal that Hawking-like… (More)

We present simple arguments that detectors moving with constant acceleration (even acceleration for a finite time) should detect particles. The effect is seen to be universal. Moreover, detectors… (More)

In this paper we construct and analyze new classes of wormhole and flux tube-like solutions for the 5D vacuum Einstein equations. These 5D solutions possess generic local anisotropy which gives rise… (More)

In Abelian theories of monopoles the magnetic charge is required to be enormous. Using the electric-magnetic duality of electromagnetism it is argued that the existence of such a large,… (More)

We present a simple and general procedure for calculating the thermal radiation coming from any stationary metric. The physical picture is that the radiation arises as the quasi–classical tunneling… (More)

A theory containing both electric and magnetic charges is formulated using two vector potentials, A and C. This has the aesthetic advantage of treating electric and magnetic charge both as gauge… (More)

In this article we use the idea of algorithmic complexity (AC) to study various cosmological scenarios, and as a means of quantizing the gravitational interaction. We look at 5D and 7D cosmological… (More)

We compare the response function of an Unruh-DeWitt detector for different space-times and different vacua and show that there is a detailed violation of the equivalence principle. In particular… (More)
