Simeon Hellerman, Conformal field theory at large fermion charge (4:00 PM - 5:30 PM)

-- Abstract: Recent years have seen a systematic study of conformal field theories at large quantum number, finding a pattern of semiclassicalization of the theory in low-lying states of large quantum number, even when the underlying theory is strongly coupled. Most concrete analyses so far have considered the case where all the large quantum number is carried by bosonic fields; in essentially all these cases the large-charge ground state is in some kind of superfluid phase or closely related effective description. In this talk I will describe recent results on theories in which fermions carry the charge of interest. In some cases the large-charge ground state is described by a superfluid; in some cases it is described by a fermi surface, either exactly or to all orders in perturbation theory. I will discuss some implications of these results.
