Quantum photonics with non-Hermitian systems

All physical systems can be roughly divided onto two types. Namely, conservative or Hermitian systems, where the whole system energy is preserved, and non-conservative or non-Hermitian systems, where the energy can irreversibly flow between the system and its surrounding environment.

Stereo observations using SST-1M telescopes

SST-1M Cherenkov telescopes installed within the Ondřejov observatory of the Astronomical Institute of the Czech Academy of Sciences observing high-energy gamma photons have reached another technical milestone. In March 2023, the White Rabbit system was implemented, enabling accurate relative or absolute time synchronisation of both telescope systems.


10 years since Higgs boson discovery

On the occasion of the 10th anniversary of the experimental confirmation of the existence of the Higgs boson, the ATLAS and CMS collaborations at the LHC accelerator at CERN released in 2022 the most extensive overviews of experimental verification of its production methods to date [1,2]. Specifically, it concerns measuring its production rate, including the associated production with a pair of top quarks, and its decay fractions to different particles, from two photons, Z or W bosons to pairs of b-quarks.

ESO Anniversary Conference in the Senate of the Czech Republic

Last year the European Southern Observatory (ESO) celebrated 60 years of existence, and the Czech Republic also celebrated 15 years since joining ESO. On this occasion, a conference was held in the Senate of the Parliament of the Czech Republic on February 21, 2023, with the participation of ESO Director General Professor Xavier Barcons. The conference was organized by the 1st Vice-President of the Senate Prof. Jiří Drahoš, and the Vice-President of the Senate Committee on European Affairs Dr. Jiří Dušek.
