Title: Interplay of Molecular Symmetry & Strong Correlations in Molecular Junctions Abstract: Single molecule transistors offer a fascinatingly diverse range of physics due to their ultrasmall size, chemical complexity, and strong electronic interactions. They constitute a playground for… Read More

Title: Euclidean Quantum Field Theory: Axioms and Automorphic Forms Abstract: The partition functions of euclidean quantum field theory can be described as functions on the moduli space of compact manifolds with Riemanninan metric that have few generalized derivatives. The conventional derivative with respect to the… Read More

Title: Entanglement in the Quantum Hall System and a Generalized Chern-Simons Form Abstract:  We analyze some features of the entanglement entropy for an integer quantum Hall state in comparison with ideas from relativistic field theory and noncommutative geometry…. Read More

Title: Quantum Amplitudes & Classical Gravity Abstract: Scattering amplitudes in quantum field theory have a number of surprising properties. They also provide a close link between Einstein gravity and Yang-Mills theory. We can exploit this link to simplify… Read More

Title: Kochen, Specker, Bell, and Others Abstract: Work of Ernst Specker (1960), Simon Kochen and Ernst Specker (1967), and John Bell (1964) concerning the non-existence of a hidden-variables theory reproducing the predictions of Quantum Mechanics is reviewed. Subsequently,… Read More

Title: Mathieu Moonshine: quarter BPS states at the Kummer point Abstract: The elliptic genus of K3 surfaces encrypts an intriguing connection between the sporadic group Mathieu 24 and non-linear sigma models on K3, dubbed `Mathieu Moonshine’. By restricting… Read More
