Spontaneous Time Asymmetry due to Horizon

TL;DR

This paper demonstrates that quantum fields near horizons inherently break time symmetry, requiring fields to vanish at the horizon, with implications for black holes and early universe cosmology.

Contribution

It reveals spontaneous time asymmetry in quantum fields around horizons and explores phenomenological implications for black holes and the early universe.

Findings

Quantum fields must vanish at the horizon.

Spontaneous time asymmetry occurs near horizons.

Implications for black hole physics and early universe models.

Abstract

We show that quantized matter fields in the presence of background metrics with Horizon exhibit spontaneous time asymmetry. All quantized matter fields have to vanish at the horizon. Some phenemenological applications of this in the context of black holes and early universe are considered.
