RNA Identification and Detection of Nucleic Acids as Aerosols in Air Samples by Means of Photon and Electron Interactions

Instruments, 2021
This study presents a methodology to reveal traces of viral particles, as aerosol with known chemical and molecular structure, in a sample by means of photon and electron interactions. The method is based on Monte Carlo simulations and on the analysis of

Detecting photon-photon interactions in a superconducting circuit

Physical Review B, 2015
A local interaction between photons can be engineered by coupling a nonlinear system to a transmission line. The required high impedance transmission line can be conveniently formed from a chain of Josephson junctions. The nonlinearity is generated by side-coupling this chain to a Cooper pair box.

Deriving a germinal center lymphocyte migration model from two-photon data [PDF]

, 2008
Recently, two-photon imaging has allowed intravital tracking of lymphocyte migration and cellular interactions during germinal center (GC) reactions. The implications of two-photon measurements obtained by several investigators are currently the subject ...

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/c$^2$. The data approach the quark-Parton-Model (QPM) expectation at the highestpTjet values (≧4 GeV/c).

Soft photon yield in nuclear interactions

EPJ Web of Conferences, 2016
First results of the study of a soft photon yield in nucleus-nucleus collisions at 3.5 GeV per nucleon at Nuclotron (LHEP, JINR) are presented. These photons are registered by an BGO electromagnetic calorimeter built by the SVD-2 Collaboration.

Photon-photon physics at the LHC and laser beam experiments, present and future

, 2020
Under certain running conditions, the CERN Large Hadron Collider (LHC) can be considered as a photon-photon collider. Indeed, in proton-proton, proton-ion, ion-ion collisions, when incoming particles pass very close to each other in very peripheral ...

Cooperative Optical Non-linearity in a blockaded Rydberg Ensemble [PDF]

, 2011
This thesis describes the observation of a novel optical non-linearity mediated by the dipole-dipole interactions in a cold gas of Rydberg atoms. Electromagnetically induced transparency (EIT) is used to map the strong dipolar interactions onto an ...

Scattering-Based Geometric Shaping of Photon-Photon Interactions

Physical Review Letters, 2019
We construct an effective Hamiltonian of interacting bosons, based on scattered radiation off vibrational modes of designed molecular architectures. Making use of the infinite yet countable set of spatial modes representing the scattering of light, we obtain a variable photon-photon interaction in this basis.
