Probing Single-Particle Spatial Extent With Helical Neutron Wavefronts
D. Sarenac, O. Lailey, C. W. Clark +8
Distinguishing transverse coherence length from single-particle wavepacket extent is fundamentally challenging, as both manifest through spatial broadening of observed intensity pr…

One knob to tune them all: Phase-controlled photon statistics and linewidth in partially pumped atomic ensembles
Oksana Chelpanova, Martino Stefanini, Dusan Sarenac +2
We study a minimal model of collective light emission from an incoherently driven ensemble of atoms where incoherent drive is applied to only a subset of the atoms and show that bo…
