Overview
The Bogoliubov Network is a loose research collaboration in theoretical physics, inspired by the legacy of Nikolay Nikolaevich Bogoliubov (1909–1992), whose work on superfluidity, BCS theory, axiomatic quantum field theory, and statistical mechanics has shaped much of modern many-body physics. The collaboration operates as two independent research nodes — in Amsterdam and in Moscow — and has no formal affiliation with any academic institution.
The Amsterdam node focuses on analytical and numerical studies of quantum many-body systems, renormalization-group flows in effective field theories, and the Bogoliubov transformation and its extensions to interacting bosonic and fermionic systems.
Themes
Many-body quantum systems
Bogoliubov transformations, quasi-particle descriptions of superfluid and superconducting states, spin-wave theory beyond the Holstein–Primakoff approximation, and the BCS–BEC crossover.
Axiomatic and constructive QFT
Wightman axioms and their descendants, Osterwalder–Schrader reconstruction, operator-product expansions, and renormalization in lower-dimensional models.
Statistical mechanics of non-equilibrium systems
Kinetic equations, derivation of hydrodynamic behaviour from microscopic dynamics, and BBGKY hierarchies.
