A new Ising/tricritical-Ising interface: From symmetry to Rydberg atoms
António Antunes, Junchen Rong
We consider interfaces between critical spin-chains in different universality classes, described in the continuum limit by defect/interface conformal field theory (DCFT/ICFT). We f…

Bilal Hawashin, Junchen Rong, Michael M. Scherer
Spontaneous symmetry breaking can persist at all temperatures in certain biconical vector models when the underlying field theories are ultraviol…
