Concurrent computing machines and physical space-time
Philippe Matherat, Marc-Thierry Jaekel
Concrete computing machines, either sequential or concurrent, rely on an intimate relation between computation and time. We recall the general characteristic properties of physical…
Decoherence and gravitational backgrounds
Serge Reynaud, Brahim Lamine, Astrid Lambrecht +2
We study the decoherence process associated with the scattering of stochastic gravitational waves. We discuss the case of macroscopic systems, such as the planetary motion of the M…
Relativity of motion in quantum vacuum
Marc-Thierry Jaekel, Astrid Lambrecht, Serge Reynaud
The problem of relativity of motion in quantum vacuum is addressed by considering a cavity moving in vacuum in a monodimensional space. The cavity is an open system which emits pho…
Gravitational decoherence of planetary motions
Serge Reynaud, Paulo A. Maia Neto, Astrid Lambrecht +1
We study the effect of the scattering of gravitational waves on planetary motions, say the motion of the Moon around the Earth. Though this effect has a negligible influence on dis…
Quantum algebraic representation of localization and motion of a Dirac electron
Marc-Thierry Jaekel, Serge Reynaud
Quantum algebraic observables representing localization in space-time of a Dirac electron are defined. Inertial motion of the electron is represented in the quantum algebra with el…
Quantum fluctuations of vacuum stress tensors and spacetime curvatures
Marc-Thierry Jaekel, Serge Reynaud
We analyze the quantum fluctuations of vacuum stress tensors and spacetime curvatures, using the framework of linear response theory which connects these fluctuations to dissipatio…
Quantum fluctuations of position of a mirror in vacuum
Marc-Thierry Jaekel, Serge Reynaud
A mirror scattering vacuum fields is submitted to a quantum fluctuating radiation pressure. It also experiences a motional force, related to force fluctuations through fluctuation-…
Causality, stability and passivity for a mirror in vacuum
Marc-Thierry Jaekel, Serge Reynaud
The mean force exerted upon a perfect mirror moving in vacuum in a two dimensional spacetime has the same expression as the radiation reaction force computed in classical electron…
Quantum limits in interferometric measurements
Marc-Thierry Jaekel, Serge Reynaud
Quantum noise limits the sensitivity of interferometric measurements. It is generally admitted that it leads to an ultimate sensitivity, the ``standard quantum limit''. Using a sem…
Inertia of Casimir energy
Marc-Thierry Jaekel, Serge Reynaud
Moving mirrors are submitted to reaction forces by vacuum fields. The motional force is known to vanish for a single mirror uniformly accelerating in vacuum. We show that inertial…
Friction and inertia for a mirror in a thermal field
Marc-Thierry Jaekel, Serge Reynaud
The force experienced by a mirror moving in vacuum vanishes in the case of uniform velocity or uniform acceleration, as a consequence of spatial symmetries of vacuum. These symmetr…
Motional Casimir force
Marc-Thierry Jaekel, Serge Reynaud
We study the situation where two point like mirrors are placed in the vacuum state of a scalar field in a two-dimensional spacetime. Describing the scattering upon the mirrors by t…
Fluctuations and dissipation for a mirror in vacuum
Marc-Thierry Jaekel, Serge Reynaud
A mirror in the vacuum is submitted to a radiation pressure exerted by scattered fields. It is known that the resulting mean force is zero for a motionless mirror, but not for a mi…
Casimir force between partially transmitting mirrors
Marc-Thierry Jaekel, Serge Reynaud
The Casimir force can be understood as resulting from the radiation pressure exerted by the vacuum fluctuations reflected by boundaries. We extend this local formulation to the cas…
