Non trivial overlap distributions at zero temperature

We explore the consequences of Replica Symmetry Breaking at zero temperature. We introduce a repulsive coupling between a system and its unperturbed ground state. In the Replica Symmetry Breaking scenario a finite coupling induces a non trivial overlap probability distribution among the unperturbed ground state and the one in presence of the coupling. We find a closed formula for this probabili...

Decoherence at zero temperature

Most discussions of decoherence in the literature consider the high temperature regime but it is also known that, in the presence of dissipation, decoherence can occur even at zero temperature. Whereas most previous investigations all assumed initial decoupling of the quantum system and bath, we consider that the system and environment are entangled at all times. Here, we discuss decoherence fo...

The Casimir Force between Real Mirrors at Non Zero Temperature

The Casimir force between dissipative metallic mirrors at non zero temperature has recently given rise to contradictory claims which have raised doubts about the theoretical expression of the force. In order to contribute to the resolution of this difficulty, we come back to the derivation of the force from basic principles of the quantum theory of lossy optical cavities. We obtain an expressio...

One-Way Fuctions are Essential for Non-Trivial Zero-Knowledge

It was known that if one-way functions exist, then there are zero-knowledge proofs for every language in PSPACE . We prove that unless very weak one-way functions exist, ZeroKnowledge proofs can be given only for languages in BPP. For average-case de nitions of BPP we prove an analogous result under the assumption that uniform one-way functions do not exist. Thus, very loosely speaking, zero{kn...
