The Unruh thermal spectrum through scalar and fermion tunneling

نویسنده

  • Debraj Roy
چکیده

The thermal spectrum seen by accelerated observers in Minkowski space – known as the Unruh effect – is derived within the tunneling mechanism. Both Bose-Einstein and Fermi-Dirac spectrum is derived by considering tunneling of scalar and spin half particles respectively, across the accelerated Rindler horizon. Full solutions of Klein-Gordon and Dirac equations in the Rindler metric are employed to achieve this, instead of approximate solutions.

The brane universe as an Unruh observer

We make the observation that a brane universe accelerates through its bulk spacetime, and so may be interpreted as an Unruh observer. The bulk vacuum is perceived to be a thermal bath that heats matter fields on the brane. It is shown that, aside from being relevant in the early universe, an asymptotic temperature exists for the brane universe corresponding to late time thermal equilibrium with...

Singlet scalar dark matter in noncommutative space

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

Thermal Hadronization and Hawking-Unruh Radiation in QCD

We conjecture that because of color confinement, the physical vacuum forms an event horizon for quarks and gluons which can be crossed only by quantum tunneling, i.e., through the QCD counterpart of Hawking radiation by black holes. Since such radiation cannot transmit information to the outside, it must be thermal, of a temperature determined by the chromodynamic force at the confinement surfa...

We study the phenomenon of Unruh effect in a massless scalar field theory quantized on the light-front in the general light-front frame. We determine the uniformly accelerating coordinates in such a frame and through a direct transformation show that the propagator of the theory has a thermal character in the uniformly accelerating coordinate system with a temperature given by Tolman’s law. We ...

Hawking–Unruh phenomenon in the parton language

Inelastic hadron interactions at high energies are accompanied by a pulse of a strong chromo–electric field. This field leads to the decay of QCD vacuum which proceeds through the emission of partons with a thermal spectrum. In a semi–classical treatment, the effective temperature of the spectrum is determined by the acceleration of partons in the classical chromo–electric field, in accord with...
