. Using the holographic machinery built up in a previous work, we show that the hidden SL (2 , R ) symmetry of a scalar quantum field propagating in a Rindler spacetime admits an enlargement in terms of a unitary positive-energy representation of Virasoro algebra defined in the Fock representation. That representation has central charge c = 1. The Virasoro algebra of operators gets a manifest geometrical meaning if referring to the holographically associated QFT on the horizon: It is nothing but… 

Holography and SL(2,R) symmetry in 2D Rindler space–time

It is shown that it is possible to define quantum field theory of a massless scalar free field on the Killing horizon of a 2D Rindler space–time. Free quantum field theory on the horizon enjoys

Quantum Thermodynamics of Black Hole Horizons

Exploiting results recently proved in a technical paper (and some of them are reviewed herein in the language of theoretical physicists) we focus on quantization of the metric of a black hole

Addendum to: Bose-Einstein Condensate and Spontaneous Breaking of Conformal Symmetry on Killing Horizons, J. Math. Phys. 46, 062303 (2005)

In the paper cited in the title local scalar QFT (in Weyl algebraic approach) has been constructed on degenerate semi-Riemannian manifolds S1 x Σ corresponding to the extension of Killing horizons by

Bose-Einstein condensate and Spontaneous Breaking of Conformal Symmetry on Killing Horizons

Local scalar QFT (in Weyl algebraic approach) is constructed on degenerate semi-Riemannian manifolds corresponding to Killing horizons in spacetime. Covariance properties of the $C^*$-algebra of

Holography and Conformal Symmetry near black hole horizons

We show here how it is possible to build a QFT on the horizon of a Schwarzschild-like spacetime. That theory, found by restricting bulk quantum elds on the horizon, is equivalent to QFT on the bulk.

Noncommutative Spectral Invariants and Black Hole Entropy

Abstract.We consider an intrinsic entropy associated with a local conformal net by the coefficients in the expansion of the logarithm of the trace of the “heat kernel” semigroup. In analogy with Weyl

On localization and position operators in Mobius covariant theories

Some years ago it was shown that, in some cases, a notion of locality can arise from the symmetry group of the theory [1–3], i.e. in an intrinsic way. In particular, when the Mobius covariance is

Algebra of conserved quantities in curved spacetime

In General Relativity (GR) finding out geodesics of a given spacetime manifold is an important task because it determines what are the classical processes which are dynamically forbidden. Conserved

A proof of the generalized second law for rapidly changing fields and arbitrary horizon slices

The generalized second law is proven for semiclassical quantum fields falling across a causal horizon, minimally coupled to general relativity. The proof is much more general than previous proofs in

De Sitter quantum scalar field and horizon holography

We show explicitly that free quantum field theory in de Sitter background restricted on the cosmological horizon produces another quantum field theory unitarily equivalent with the original one.

Looking beyond the Thermal Horizon: Hidden Symmetries in Chiral Models

In thermal states of chiral theories, as recently investigated by H.-J. Borchers and J. Yngvason, there exists a rich group of hidden symmetries. Here we show that this leads to a radical converse of

If one assumes the validity of conventional quantum field theory in the vicinity of the horizon of a black hole, one does not find a quantum mechanical description of the entire black hole that even

It is shown that the global charges of a gauge theory may yield a nontrivial central extension of the asymptotic symmetry algebra already at the classical level. This is done by studying three
