Dirac Families for Loop Groups as Matrix Factorizations
Daniel S. Freed, Constantin Teleman
We identify the category of integrable lowest-weight representations of the loop group LG of a compact Lie group G with the linear category of twisted, conjugation-equivariant curv…

Short-range entanglement and invertible field theories
Daniel S. Freed
Quantum field theories with an energy gap can be approximated at long-range by topological quantum field theories. The same should be true for suitable condensed matter systems. Fo…

Anomalies and Invertible Field Theories
Daniel S. Freed
We give a modern geometric viewpoint on anomalies in quantum field theory and illustrate it in a 1-dimensional theory: supersymmetric quantum mechanics. This is background for the…
