Problems in higher genus superstring amplitudes
Sergio Cacciatori - University of Insubria
I would like to provide a short, possibly elementary, introduction to the problem of computing string amplitudes at higher genus for superstrings. Essentially, I will recall which is the mathematical problem in defining the path integral measure (which has a well defined algebraic geometry… -
Astrophysics and Cosmology through Problems - 6B
Mark Wyman - PDT Partners LLC , Niayesh Afshordi - University of Waterloo
This course is aimed at advanced undergraduate and beginning graduate students, and is inspired by a book by the same title, written by Padmanabhan. Each session consists of solving one or two pre-determined problems, which is done by a randomly picked student. While the problems introduce various… -

Simulation of quantum many-body systems with tensor network methods
Roman Orus - University of the Basque Country
In this talk I will give an introduction to the simulation of quantum many-body systems using the so-called tensor networks. After a brief historical review, I will introduce the basics on tensor network representations of quantum states, and will explain some recent developments. In particular, in… -

Dirac's penumbra: constraints and gauge transformations in reparametrization invariant theories
Brendan Foster - Utrecht University
A simple theorem of Dirac identifies primary first-class constraints as generators of transformations, \'that do not affect the physical state\'. This result has profound implications for the definition of physical states and observables in the quantization of constrained systems, and leads to one…
First results from the South Pole Telescope (SPT)
The South Pole Telescope (SPT) is a 10-meter submm-wave telescope optimized for large-field imaging of the cosmic microwave background (CMB) at arcminute resolution. The first key project of the SPT is a large area survey to find galaxy clusters using the Sunyaev-Zel\'dovich effect. Combined with…-

Explorations of Covariant Canonical Gravity
Andy Randono - Paper
The standard Hamiltonian formulation of (first order) gravity breaks manifest covariance both in its retention of the Lorentz group as a local gauge group and in its discrepant treatment of spacelike and timelike diffeomorphisms. Here we promote more covariant alternatives for canonical quantum…-
