The Bogoliubov Network

Amsterdam node — many-body quantum theory, QFT, statistical mechanics

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.

"Mathematical rigour in theoretical physics is not a luxury but a tool to distinguish the robust from the accidental." — adapted from the preface to Introduction to Axiomatic Quantum Field Theory, 1975.

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.
