BTW brief off-topic comment---Atyy I know you have expressed interest in Brian Swingle's work from time to time. He just gave a talk at Perimeter which is on video. Google "pirsa swingle".
The topic is entanglement in connection with the Fractional Quantum Hall Effect. So condensed matter and emergence---topics which interest you. A lot of XG Wen papers are cited throughout the talk, as I recall, and he was your teacher. So it is possible you would like this video lecture.
