Title: Quantum Fluctuations of Fields and Stress Tensors
Authors: L. H. Ford
Abstract summary: Review of recent work on quantum fluctuations of the electric field and of stress tensor operators and their physical effects. For quadratic operators, such as the energy density, can have a more slowly decreasing tail, leading to an enhanced probability of large fluctuations. Some possible physical effects of these large fluctuations will be discussed.

Abstract: This is a review of recent work on quantum fluctuations of the electric field and of stress tensor operators and their physical effects. The probability distribution for vacuum fluctuations of the electric field is Gaussian, but that for quadratic operators, such as the energy density, can have a more slowly decreasing tail, leading to an enhanced probability of large fluctuations. This effect is very sensitive to the details of how the measurement is performed. Some possible physical effects of these large fluctuations will be discussed.

Oscillating Fields, Emergent Gravity and Particle Traps [55.2480439325792]
We study the large-scale dynamics of charged particles in a rapidly oscillating field and formulate its classical and quantum effective theory description. Remarkably, the action models the effects of general relativity on the motion of nonrelativistic particles, with the values of the emergent curvature and speed of light determined by the field spatial distribution and frequency.

Quantum interaction of sub-relativistic aloof electrons with mesoscopic samples [91.3755431537592]
Relativistic electrons experience very slight wave packet distortion and negligible momentum recoil when interacting with nanometer-sized samples. Modelling fast electrons as classical point-charges provides extremely accurate theoretical predictions of energy-loss spectra.

Detectable Signature of Quantum Friction on a Sliding Particle in Vacuum [58.720142291102135]
We show traces of quantum friction in the degradation of the quantum coherence of a particle. We propose to use the accumulated geometric phase acquired by a particle as a quantum friction sensor. The experimentally viable scheme presented can spark renewed optimism for the detection of non-contact friction.

We show that non-contact friction enhances the decoherence of the moving atom. We suggest that measuring decoherence times through velocity dependence of coherences could indirectly demonstrate the existence of quantum friction.

Zitterbewegung and Klein-tunneling phenomena for transient quantum waves [77.34726150561087]
We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.

On an electrodynamic origin of quantum fluctuations [0.0]
We show that violent fluctuations are experienced by an electromagnetic charged extended particle when it is perturbed from its rest state. We derive a series expansion of the self-potential, which in addition to rest and kinetic energy, gives rise to a new contribution that shares features with the quantum potential.
