On the 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…

Numerical evidence of a critical point in the (2+1)D SO(5) nonlinear sigma model with Wess-Zumino-Witten term

Yuan Da Liao, Bin-Bin Chen, Junchen Rong +3

We develop an optimized continuous-field quantum Monte Carlo (QMC) algorithm to investigate the projected SO(5) nonlinear sigma model with a Wess-Zumino-Witten term, which describe…
