The Casimir stress on a spherical shell in de Sitter spacetime for a massless scalar field is
calculated using Krein space quantization. In this method, the auxiliary negative frequency …

There are some fundamental questions in quantum physics and quantum field theory which
can not be answered considering the positive energy states, alone. Negative energy states …

In this paper we have a brief review on the problem of divergence in quantum field theory
and its elimination using the method of Krein space quantization. In this method, the …
