Space‐Time Wave Packets from Smith‐Purcell Radiation [PDF]
Advanced Science, 2021 Space‐time wave packets are electromagnetic waves with strong correlations between their spatial and temporal degrees of freedom. These wave packets have gained much attention for fundamental properties like propagation invariance and user‐designed group

Space-time wave packets localized in all dimensions [PDF]
Nature Communications, 2022 Propagation-invariant wave packets confined in space and time can be useful for optical sensing, imaging, and nonlinear and quantum optics. Here the authors demonstrate control over the angular dispersion of optical wave packets in two-transverse ...

Quaternionic Wave Packets [PDF]
Journal of Mathematical Physics, 2007 We compare the behavior of a wave packet in the presence of a complex and a pure quaternionic potential step. This analysis, done for a gaussian convolution function, sheds new light on the possibility to recognize quaternionic deviations from standard ...

Free-space optical delay line using space-time wave packets [PDF]
Nature Communications, 2020 Delay lines are a critical part of future optical communications. Here, the authors create a delay line in free space by tuning the group velocities of multiple inline space-time wavepackets to introduce different delays.

Wave packets and quantum oscillations [PDF]
International Journal of Modern Physics A, 2004 We give a detailed analysis of the oscillation formula within the context of the wave packet formalism. Particular attention is made to insure flavor eigenstate creation in the physical cases (Delta p not equal 0).

Hanbury Brown–Twiss Effect with Wave Packets [PDF]
Quanta, 2017 The Hanbury Brown–Twiss (HBT) effect, at the quantum level, is essentially an interference of one particle with another, as opposed to interference of a particle with itself.

ACM Transactions on Graphics, 2017 This paper presents a method for simulating water surface waves as a displacement field on a 2D domain. Our method relies on Lagrangian particles that carry packets of water wave energy; each packet carries information about an entire group of wave trains, as opposed to only a single wave crest.

Higher-order spatiotemporal wave packets with Gouy phase dynamics [PDF]
NanophotonicsSpatiotemporal (ST) wave packets constitute a broad class of optical pulses whose spatial and temporal degrees of freedom cannot be treated independently.

Cherenkov Radiation Control via Self-accelerating Wave-packets [PDF]
Scientific Reports, 2017 Cherenkov radiation is a ubiquitous phenomenon in nature. It describes electromagnetic radiation from a charged particle moving in a medium with a uniform velocity larger than the phase velocity of light in the same medium.

Demonstration of propagation-invariant 3D space-time wave packets [PDF]
EPJ Web of Conferences, 2022 We present the first demonstration of propagation-invariant space-time (ST) wave packets localized in all dimensions - 2D space and 1D time. By introducing orbital-angular-momentum into the wave packets, we produce propagation-invariant ST-OAM wave ...
