Theoretical research in the Joint Institute for High Temperature of RAS on the intense laser interaction with matter are discussed in view of current and future experiments, in particular with PHELIX at GSI-FAIR, Darmstadt.

A wide-range models elaborated in JIHT RAS are used for the description of material response on the intense laser action. Comparison of experimental findings with the results of simulation is used both for the numerical model verification and for estimations of the interaction parameters that cannot be measured directly in experiments.

Electron acceleration mechanisms are discussed and analysis of the experimental data on X-ray generation at relativistic laser intensities is presented. Generation of energetic electron bunches in the laser interaction with low density targets, and also with preplasma created by laser prepulses at grazing incidence to solid targets are under discussion.
The theoretical support of laser-matter experiments and optimization of secondary sources of high energy particles and photons for warm dens matter diagnostics are considered.

Summary: Gyorgy Buzsaki aims at understanding how neuronal circuitries of the brain support its cognitive capacities, with a primary interest in brain oscillations, synchronization and memory. His major goal is to provide rational, mechanistic explanations of cognitive functions at a descriptive level.
Over the past 35 years, Buzsaki has led the way in analyzing the functional properties of cortical neurons acting within their natural networks. He pioneered the experimental exploration of how coordinated, rhythmic neuronal activity serves physiological functions in the cerebral cortex, and in particular, how information is exchanged between the hippocampus and neocortex. For this aim, Buzsaki's lab has established some of the most difficult approaches necessary to solve these problems. His work includes innovative techniques to monitor neural activity and brain oscillation in behaving rodents from the cellular level to whole network activation.
In addition to his numerous publications and reviews, Gyorgy Buzsaki is the author of the book "Rhythms of the Brain", which discusses mechanisms and functions of neuronal synchronization. He explains the field of brain oscillations, and how oscillatory timing is the brain’s fundamental organizer of neuronal information. Among many other distinguished awards, he is the recipient of the 2011 European brain prize.

Iron-based pnictide superconductors display the phenomenon of electronic nematicity - the electronic transport displays an anisotropic behavior that breaks the rotational symmetry of the lattice. This nematic behavior is observed across many compounds and over a large part of the phase diagram of the material. What is this nematicity? Does it have any relationship to superconductivity in the material? In this talk I will attempt to answer these questions by providing a microscopic view of one of the pnictide compounds NaFeAs obtained using atomic-resolution scanning tunneling microscopy and spectroscopy.
