Global Fixed Point Potentials in the Abelian Higgs Model with flavors

Gergely Fejős, Shunsuke Yabunaka

Existence of charged fixed points in the Abelian Higgs model with flavors in dimensions is studied using the functional renormalization group. We numerically solve the coup…

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…

The finite origin of the Bardeen-Moshe-Bander phenomenon and its extension at by singular fixed points

Claude Fleming, Bertrand Delamotte, Shunsuke Yabunaka

We study the model in dimension three (3) at large and infinite and show that the line of fixed points found at --the Bardeen-Moshe-Bander (BMB) line-- has…

Full Counting Statistics of Spin-Flip/Conserving Charge Transitions in Pauli-Spin Blockade

Sadashige Matsuo, Kazuyuki Kuroyama, Shunsuke Yabunaka +4

We investigate the full counting statistics (FCS) of spin-conserving and spin-flip charge transitions in Pauli-spin blockade regime of a GaAs double quantum dot. A theoretical mode…
