Lyapunov exponents


The concept of Lyapunov exponent goes back to Lyapunov's 1892 thesis on the stability of differential equations, and has numerous applications in various branches of mathematics and science.
Starting from the 1960s, it found its proper mathematical framework in ergodic theory, where it has had a prominent role ever since. In this colloquium lecture I will review a few recent developments, especially about the way Lyapunov exponents depend on the underlying dynamical system. ...

Direct photons from magnetized quark-gluon plasma


Abstract: trong magnetic fields play an important role in the physics of hot quark-gluon plasma produced in heavy-ion collisions. Most interestingly, they can trigger quantum anomalous processes leading to unusual charged-particle correlations in the observable data. The direct verification of the corresponding theoretical prediction is, however, complicated by a large uncertainty in the magnetic field produced in collisions. To constrain the uncertainty, one needs an independent measurement of the field. The direct photon emission could potentially provide such a measurement. In this talk, the recent first-principle calculations of the direc ...
