Probability and Mathematical Physics Seminar
Bijecting the BKT transition
Speaker: Piet Lammers, CNRS and LPSM
Location: Warren Weaver Hall 1302

The 2D XY model has attracted attention of physicists and mathematicians for several decades. One way to understand this model is through its dual height function. Recent developments make it possible to show that the phase transitions of the two models coincide. The talk will highlight several connections between the two models and is based on arXiv:2301.06905 (Bijecting the BKT transition) and arXiv:2211.14365 (A dichotomy theory for height functions).
