We provide a rigorous lattice approximation of conformal field theories given in terms of
lattice fermions in 1+ 1-dimensions, focussing on free fermion models and Wess–Zumino …

We analyze the renormalization group fixed point of the two-dimensional Ising model at
criticality. In contrast with expectations from tensor network renormalization (TNR), we show …

Many features of physical systems, both qualitative and quantitative, become sharply
defined or tractable only in some limiting situation. Examples are phase transitions in the …

Given a unitary fusion category, one can define the Hilbert space of a so-called “anyonic
spin-chain” and nearest neighbor Hamiltonians providing a real-time evolution. There is …
