This volume contains the proceedings of the
QMATH13: Mathematical Results in Quantum Physics conference, held from
October 8–11, 2016, at the Georgia Institute of Technology,
Atlanta, Georgia.

In recent years, a number of new frontiers
have opened in mathematical physics, such as many-body localization
and Schrödinger operators on graphs. There has been progress in
developing mathematical techniques as well, notably in renormalization
group methods and the use of Lieb–Robinson bounds in various
quantum models.

The aim of this volume is to provide an
overview of some of these developments. Topics include random
Schrödinger operators, many-body fermionic systems, atomic
systems, effective equations, and applications to quantum field
theory. A number of articles are devoted to the very active area of
Schrödinger operators on graphs and general spectral theory of
Schrödinger operators. Some of the articles are expository
and can be read by an advanced graduate student.

#### Readership

Graduate students and research mathematicians interested in current developments in mathematical physics.
