Mass generation at a fixed point: A Functional Renormalization Group Study of the tricritical O() model in and
Shunsuke Yabunaka, Bertrand Delamotte
Renormalization group (RG) fixed points are commonly associated with scale invariance and a divergent correlation length. We show that this connection can fail in the tricritical $…

Drag Coefficient in Near-Critical Binary Mixtures: Solving Hydrodynamic Fields with Improved Numerics
Shunsuke Yabunaka
We calculate the drag coefficient of a spherical particle suspended in a near-critical binary fluid mixture. To capture the scaling behavior associated with critical adsorption in…

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…
