Cosmic rays, the relativistic component of diffuse astrophysical plasma, exchange energy and momentum with the thermal gas collisionlessly, mediated by the ambient magnetic field. Some but not all models of this interaction show that cosmic rays can...

The prospect of an ultra-light dark matter particle (also known as Fuzzy Dark Matter, or FDM) has recently drawn attention as a promising alternative to standard Cold Dark Matter (CDM). When the mass of the particle reaches below 10^-21 eV, quantum...

Edge excitations of (2+1)D topological phases are usually described using continuum field theories. But the boundaries of some (2+1)D topological phases can also be described using lattice-like edge theories that have a finite dimensional Hilbert...

 q-deformed Virasoro and W-algebras were defined a quarter century ago with the aim of furthering our understanding of two-dimensional integrable and conformal field theories, while also developing the representation theory of so-called quantum...

Understanding of the role magnetic field in astrophysical environments is essential for many brunches of astrophysical research. The knowledge of magnetic field and polarized radiation that this field induces is important for the ongoing search for...

We study the Lyapunov exponent in disordered quantum field theories. Generically the Lyapunov exponent can only be computed in isolated CFTs, and little is known about the way in which chaos grows as we deform the theory away from weak coupling. In...

In this talk I will discuss two undetected populations of black holes. In the faraway Universe, the first lensed z > 6 quasar (J0439+1634) was recently discovered. We predicted that the observed population of quasars should contain many mildly...
