Neutrino-Antineutrino Asymmetry around Rotating Black Holes [PDF]
, 2003 Propagation of fermion in curved space-time generates gravitational interaction due to the coupling between spin of the fermion and space-time curvature.

Chronology Protection in Generalized Godel Spacetime [PDF]
, 2002 The effective action of a free scalar field propagating in the generalized Godel spacetime is evaluated by the zeta-function regularization method. From the result we show that the renormalized stress energy tensor may be divergent at the chronology ...

Signatures of Planck-scale interactions in the cosmic microwave background?
, 2006 Based on a rather general low-energy effective action (interacting quantum fields in classical curved space-times), we calculate potential signatures of new physics (such as quantum gravity) at ultra-high energies (presumably the Planck scale) in the ...

Table-top creation of entangled multi-keV photon pairs via the Unruh effect
, 2007 Electrons moving in a strong periodic electromagnetic field (e.g., laser or undulator) may convert quantum vacuum fluctuations into pairs of entangled photons, which can be understood as a signature of the Unruh effect. Apart from verifying this striking

The asymptotic behavior of Casimir force in the presence of compactified universal extra dimensions [PDF]
, 2006 The Casimir effect for parallel plates in the presence of compactified universal extra dimensions within the frame of Kaluza-Klein theory is analyzed. Having regularized and discussed the expressions of Casimir force in the limit, we show that the nature

Dielectric black hole analogues
, 2001 Alternative to the sonic black hole analogues we discuss a different scenario for modeling the Schwarzschild geometry in a laboratory - the dielectric black hole.

Finite-temperature effective boundary theory of the quantized thermal Hall effect
New Journal of Physics, 2016 A finite-temperature effective free energy of the boundary of a quantized thermal Hall system is derived microscopically from the bulk two-dimensional Dirac fermion coupled with a gravitational field.

Signatures of the Unruh effect from electrons accelerated by ultra-strong laser fields
, 2006 We calculate the radiation resulting from the Unruh effect for strongly accelerated electrons and show that the photons are created in pairs whose polarizations are maximally entangled. Apart from the photon statistics, this quantum radiation can further

Quantum circuit model for non-inertial objects: a uniformly accelerated mirror
New Journal of Physics, 2017 We develop a quantum circuit model describing unitary interactions between quantum fields and a uniformly accelerated object in two spacetime dimensions, and apply it to a semi-transparent mirror that uniformly accelerates in the Minkowski vacuum.

On the Universality of the Hawking Effect
, 2004 Addressing the question of whether the Hawking effect depends on degrees of freedom at ultra-high (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of freedom under which the Hawking effect is reproduced to ...
