April 2023: Towards a tunable laser in the Terahertz range.
Researchers have succeeded in generating an intense photon emission that can be tuned over the entire Terahertz frequency range by both the magnetic field and the electron density present in the material under study. This discovery opens up the possibility of developing a compact laser source with a constant magnetic field, tunable over the entire Terahertz spectrum by adjusting only a gate voltage. More details.

The different curves refer to different photon energies, corresponding to frequencies from 250 GHz to 3.1 THz. This family of curves shows indirectly that the energy of the emitted photons varies continuously with the applied magnetic field. Charles Coulomb Laboratory
January 2023: Nature Photonics: Terahertz cyclotron emission of two-dimensional Dirac fermions.
Landau emission from Dirac fermions in graphene-like HgTe quantum wells is experimentally demonstrated. The emission is shown to be tunable by both the magnetic field and the carrier concentration. these results represent an advance in the realization of terahertz Landau lasers tunable by a magnetic field and gate voltage.

February 28, 2022: Article in Physics World: Experimental evidence found for long-distance intermolecular forces
Experimental evidence of long-range attractive forces between cellular proteins has been obtained by researchers in France more than 50 years after the idea was first proposed. The forces are mediated by electromagnetic radiation, and they could explain how molecules find their targets inside the crowded interiors of living cells. More details.
