Abstract

The which-way information and interference visibility in a temporal version of double- and triple-slit experiments with attosecond electron wave packets generated by a soft X-ray pulse train can be controlled by a phase-stabilized laser pulse.

Attosecond Double-Slit Experiment

F. Lindner, Michael G. Schätzel, HERBERT WALTHER +7 more

A new scheme for a double-slit experiment in the time domain is presented. Phase-stabilized few-cycle laser pulses open one to two windows (slits) of attosecond duration for photoionization. Fringes in the angle-resolved energy spectrum of varying visibility depending on the degree of which-way information are measured. A situation in which one and the same electron encounters a single and a double slit at the same time is observed. The investigation of the fringes makes possible interferometry on the attosecond time scale. From the number of visible fringes, for example, one derives that the slits are extended over about 500 as.

Temporal Young’s interference experiment by attosecond double and triple soft-x-ray pulses

Kenichi L. Ishikawa

We study a temporal version of Young's interference experiment by attosecond soft-x-ray pulses. The photoelectron energy spectra by attosecond double pulses exhibit an interference pattern, since we have no information on which pulse has generated the electron. We can re-establish the ``which-way'' information and control the interference visibility by changing the electron's momentum with phase-stabilized laser pulses, by an amount depending on the time of ionization. Moreover, if we use a triple pulse, we can realize a situation where the electron passes through a single and a double slit simultaneously to the same direction and is observed by the same detector.

An Attosecond Crossover Test for the Relativistic Temporal Interpretation of Wave–Particle Duality

Aqeel Raja

This paper presents a quantitative proof attempt and experimental test program for the previously published Relativistic Temporal Interpretation (RTI) of wave–particle duality and quantum uncertainty. The earlier RTI paper proposed that wave-like and particle-like manifestations may be separated or organized by an effective relativistic temporal distinguishability scale. The present work does not restate the theory from the beginning; instead, it develops testable consequences of that published interpretation. Published complementarity data are mapped into a temporal coherence form, and controlled electron double-slit diffraction is used to derive a falsifiable attosecond-scale crossover prediction. For the 50–62 nm electron slit-width bracket, the model predicts a robust experimental search window of approximately 470–540 eV. Independent attosecond time-domain double-slit experiments are also discussed as supporting evidence that electron interference, which-way information, and attosecond timing can be experimentally connected. The paper concludes that a dedicated electron energy-scan experiment remains required for decisive confirmation.
