Nonequilibirum Thermodynamics of Biochemical Circuits: Some Recent Results A central problem in biology is how living systems manage to perform vital functions (e.g., replication, development, computing, etc.) accurately by using inherently stochastic biochemical circuits to process highly noisy information. What are the molecular mechanisms to control noise for accurate information processing? ... Read more

Long-range orientational order in 2D active matter The birth of active matter physics may be traced back to 1995, when Tamas Vicsek and collaborators proposed to see collective motion as a spontaneously broken symmetry phase and introduced the now-famous Vicsek model. The same year, John Toner and Yuhai Tu, inspired by Vicsek, wrote down a field theory for this flying XY spin model, and obtained their landmark result: polar flocks can exhibit true long-range orientational order even in 2D. ...

Hydrodynamics of integrable many-body systems Integrable many-body systems can be characterised by having an extensive number of local conservation laws. On the hydrodynamic scale (Euler), one thus expects to have a coupled system of a large number of hyperbolic conservation laws. They have a very particular structure known as generalised hydrodynamics. In my talk the classical Toda lattice will be used as an illustration. ... Read more

Quantum thermalization and many-body localization: some fundamentals of quantum statistical mechanics. Most physical systems that contain many interacting degrees of freedom that are excited to energies well above of the ground state do act as a “bath” or “reservoir” for their own subsystems and thus go to thermal equilibrium under ...
