Two lines of critical points described by CFTs with different central charges intersect. What happens?
There is a lovely set of two-parameter spin chains that can be mapped to quadratic fermions and studied quite exactly:
$$H = -\sum_{i} \frac{1+\gamma}{2}\sigma^x_i\sigma^x_{i+1}+\frac{1-\gamma}{2}\...

Log-law entanglement with large central charge contradict bounds on the entanglement entropy
I am trying to learn more about entanglement entropy in large but finite-size systems at critical points. I am still relatively new to conformal field theory, so it is not unlikely I have ...
