The Laboratory for Quantum Theory of Intense Fields has received a grant of the Russian Science Physics Foundation to study quantum effects in strong electromagnetic fields. This is fundamental research in theoretical physics, the results of which will help to clarify how these quantum effects influence the optical properties of nanomaterials and the generating of strong electromagnetic fields near black holes and neutron stars.
In recent years, the situation has changed dramatically: the creation of super-power laser systems, new advances in observational astrophysics, and particle physics have opened up opportunities for a large number of applications of quantum effects in strong fields in astrophysics, cosmology, neutrino physics, and nuclear physics, and in the rapidly developing physics of nanostructures, especially in the physics of graphene.
The grant awarded is devoted both to the further development of this theory and its applications to a number of important physics problems. One of them is the description of quantum effects in nanostructures (in particular, in graphene) caused by the occurrence of specific electronic excitations from vacuum instability, and their effect on conductivity and radiation. Another line of research concerns the possibility of generating strong electromagnetic fields near astrophysical objects such as black holes and neutron stars. Related tasks are closely linked to neutrino physics and to the chiral magnetic effect (CME) that has been intensively discussed recently.
