Seven- and eight-loop critical exponents of the three-dimensional Ising model
D. Shapoval, Yu. Honchar, B. Delamotte +2
We determine the critical exponents , , and the correction-to-scaling exponent of the three-dimensional Ising universality class by resumming the recently computed sev…

Global fixed point potential approach to frustrated antiferromagnets
Shunsuke Yabunaka, Bertrand Delamotte
We revisit the critical behavior of classical frustrated systems using the nonperturbative renormalization group (NPRG) equation. Our study is performed within the local potential…

Conformal invariance and composite operators: A strategy for improving the derivative expansion of the nonperturbative renormalization group
Bertrand Delamotte, Gonzalo De Polsi, Matthieu Tissier +1
It is expected that conformal symmetry is an emergent property of many systems at their critical point. This imposes strong constraints on the critical behavior of a given system.…
