Ladislav Šamaj is a Research Professor within the Institute of Physics at the Slovak Academy of Sciences and teaches statistical mechanics of integrable many-body systems at the Institute of Physics and the Comenius University in Bratislava. His research specialises in Coulomb fluids, classical and quantum, two-dimensional and higher-dimensional. He contributed to the field of equilibrium statistical mechanics by solving exactly the two-dimensional Coulomb gas, charge-symmetric and with a charge asymmetry. Zoltán Bajnok is a Research Professor at the MTA Lendület Holographic QFT Group of the Wigner Research Centre for Physics in Budapest, where he specialises in integrable models with a focus on finite size effects. He contributed to the analysis of the exact spectrum of the boundary sine-Gordon theory, and successfully applied the developed 2D integrable techniques to calculate the scaling dimensions of gauge invariant operators in four-dimensional quantum field theories.
