Quantum Observables associated with Einstein Localisation
Marc-Thierry Jaekel, Serge Reynaud
The description of relativistic effects requires a preliminary definition of events localised in space-time while the clocks used for time definition and the fields used in synchro…
Observable Dirac Electron in Accelerated Frames
Marc-Thierry Jaekel, Serge Reynaud
We present a new quantum algebraic description of an electron localized in space-time. Positions in space and time, mass and Clifford generators are defined as quantum operators. C…
Quantum Localisation Observables and Accelerated Frames
Marc-Thierry Jaekel, Serge Reynaud
We define quantum observables associated with Einstein localisation in space-time. These observables are built on Poincare' and dilatation generators. Their commutators are given b…
Generating photon pulses with an oscillating cavity
A. Lambrecht, M. T. Jaekel, S. Reynaud
We study the generation of photon pulses from thermal field fluctuations through opto-mechanical coupling to a cavity with an oscillatory motion. Pulses are regularly spaced and be…
Frequency up-converted radiation from a cavity moving in vacuum
A. Lambrecht, M. T. Jaekel, S. Reynaud
We calculate the photon emission of a high finesse cavity moving in vacuum. The cavity is treated as an open system. The field initially in the vacuum state accumulates a dephasing…
Logical Dissipation of Automata Implements - Dissipation of Computation
Philippe Matherat, Marc-Thierry Jaekel
As revealed by discussions of principle on energy dissipation by computers, logic imposes constraints on physical systems designed for a logical function. We define a notion of log…
Gravitational Quantum Limit for Length Measurements
Marc-Thierry Jaekel, Serge Reynaud
We discuss a limit for sensitivity of length measurements which is due to the effect of vacuum fluctuations of gravitational field. This limit is associated with irreducible quantu…
Quantum Fluctuations of Mass for a Mirror in Vacuum
Marc-Thierry Jaekel, Serge Reynaud
A mirror in vacuum is coupled to fluctuating quantum fields. As a result, its energy-momentum and mass fluctuate. We compute the correlation spectra of force and mass fluctuations…
Quantum Langevin Equations and Stability
Marc-Thierry Jaekel, Serge Reynaud
Different quantum Langevin equations obtained by coupling a particle to a field are examined. Instabilities or violations of causality affect the motion of a point charge linearly…
Relativity of Motion in Vacuum
Marc-Thierry Jaekel, Astrid Lambrecht, Serge Reynaud
The existence of vacuum fluctuations leads to reconsider the question of relativity of motion. The present article is devoted to this aim with a main line which can be formulated a…
The Casimir force for passive mirrors
A. Lambrecht, M. -T. Jaekel, S. Reynaud
We show that the Casimir force between mirrors with arbitrary frequency dependent reflectivities obeys bounds due to causality and passivity properties. The force is always smaller…
