Wave packet splitter and rectificator based on the Dirac delta potentials in a fractional medium [PDF]
Scientific ReportsIn this work, we have investigated the Gaussian and Airy wave packets colliding on the Dirac delta potentials. We have used the time-dependent space-fractional Schrodinger equation and solved it by using the slit step finite difference method.

Thermalization Induced by Quantum Scattering
PRX Quantum, 2021 We use quantum scattering theory to study a fixed quantum system Y subject to collisions with massive particles X described by wave packets. We derive the scattering map for system Y and show that the induced evolution crucially depends on the width of ...

Quadrics for Structuring Invariant Space-Time Wave Packets [PDF]
EPJ Web of Conferences, 2022 We provide a general approach for structuring invariant 3D+1 optical wave packets in both bulk and structured dispersive media, through a simple engineering of phase-matched space-time frequencies on quadric surfaces.

Wave packets losing their covariance
Nuclear Physics B, 2020 In neutrino physics, it is sometimes assumed that all wave packets must transform covariantly as Lorentz vectors. We show in a simple example that even if the initial conditions of a wave packet are covariant, then evolution in a relativistic interacting

Isochronous space–time wave packets [PDF]
Optics Letters, 2021 The group delay incurred by an optical wave packet depends on its path length. Therefore, when a wave packet is obliquely incident on a planar homogeneous slab, the group delay upon traversing it inevitably increases with the angle of incidence.

Strong double space-time wave packets using optical parametric amplification
Communications Physics, 2022 Space-time wave packets are optical pulses synthesized from light waves carrying strong correlations between their spatial and temporal degrees of freedom and show many anomalous behaviors such as superluminal propagation.

Nondiffracting gravitational waves
European Physical Journal C: Particles and Fields, 2021 It is proved that accelerating nondiffracting gravitational Airy wave-packets are solutions of linearized gravity. It is also showed that Airy functions are exact solutions to Einstein equations for non-accelerating nondiffracting gravitational wave ...

Nuclear Physics B, 2021 We examine the potential of the future medium-baseline reactor neutrino oscillation (MBRO) experiments in studying neutrino wave-packet impact. In our study, we treat neutrinos as wave packets and use the corresponding neutrino flavor transition ...

Edge-Magnetoplasmon Wave-Packet Revivals in the Quantum Hall Effect [PDF]
, 1996 The quantum Hall effect is necessarily accompanied by low-energy excitations localized at the edge of a two-dimensional electron system. For the case of electrons interacting via the long-range Coulomb interaction, these excitations are edge ...
