Abstract How does the quantum-to-classical transition of measurement occur? This question is vital for both foundations and applications of quantum mechanics. Here, we develop a new measurement-based framework for characterizing the classical and qua

Abstract Controlling optical fields on the subwavelength scale is at the core of nanophotonics. Laser-driven nanophotonic particle accelerators promise a compact alternative to conventional radiofrequency-based accelerators. Efficient electron accele

Accurate observation of two or more particles within a very narrow time window has always been a challenge in modern physics. It creates the possibility of correlation experiments, such as the ground-breaking Hanbury Brown–Twiss experiment, leading

There is interest in controlling particle beams using electric fields and using them in compact devices. Here the authors demonstrate guiding and splitting of charged particle (electron and ion) beams on a chip designed with special structures.

In the published version of the paper, we made an error in choosing the value of the effective nuclear charge Z in equation (7). The correct value is Z = 4.00. Correcting this does not affect the main claims of the work, namely, the atomic-scale maps

When graphene is exposed to a strong few-cycle optical field, a directional electric current can be induced depending on the carrier-envelope phase of the field. This phenomenon has successfully been explained by the charge dynamics in reciprocal spa

A high-energy electron beam coupled to an optical field experiences a quantized energy modulation by multiples of the photon energy, originating from the temporal periodicity of the optical field by virtue of intercycle interference. Here we investig

Ultrafast control of electron dynamics in solid state systems has recently found particular attention. By increasing the electric field strength of laser pulses, the light–matter interaction in solids might turn from a perturbative into a novel non

We theoretically investigate the dependence of the enhancement of optical near-fields at nanometric tips on the shape, size, and material of the tip. We confirm the strong dependence of the field enhancement factor on the radius of curvature. In addi

Recently, our group has demonstrated dielectric laser acceleration of nonrelativistic electrons at a scalable fused silica grating [J. Breuer and P. Hommelhoff, Phys. Rev. Lett. 111, 134803 (2013)]. This represents a demonstration of the inverse Smit
