Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Photon momentum transfer and partitioning: from one to many

Nature Communications
The transfer of photon momentum is indispensable in initiating and directing light-matter interactions, which underpins a plethora of fundamental physical processes from laser cooling to laser particle acceleration.

Storing single photons emitted by a quantum memory on a highly excited Rydberg state

Nature Communications, 2017
The state of a single photon can be stored as a Rydberg excitation using electromagnetically induced transparency, and this enables nonlinear interactions at the single-photon level.

The $$\pi \eta $$ interaction and $$a_0$$ resonances in photon–photon scattering [PDF]

The European Physical Journal C, 2020
AbstractWe revisit the information on the two lightest$$a_0$$a0resonances andS-wave$$\pi \eta $$πηscattering that can be extracted from photon–photon scattering experiments. For this purpose we construct a model for theS-wave photon–photon amplitudes which satisfies analyticity properties, two-channel unitarity and obeys the soft photon as well as the ...

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Spectral signature of high-order photon processes enhanced by Cooper-pair pairing

Nature Communications
Inducing interactions between individual photons is key for photonic quantum information and studying many-body photon states. Superconducting circuits are well suited to combine strong interactions with low losses.

Scaling in the photon-photon interaction

Nuclear Physics B, 1972
Abstract Particular high-energy limits for the structure functions of the inclusive process e+e→e+e+hadrons are considered in a parton model, and shown to lead to a scaling-type behaviour.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Jet Production in Photon-Photon Interactions

Zeitschrift f�r Physik C Particles and Fields, 1987
We present results on jet production in γγ interactions where both photons are quasi-real. The invariant masses of the hadronnic system are limited to the range 4≦W vis≦12 GeV/c2. The data approach the quark-Parton-Model (QPM) expectation at the highestp jet ...
