False vacuum decay in kink scattering
Journal of High Energy Physics, 2018 In this work we consider kink-antikink and antikink-kink collisions in a modified ϕ 4 model with a false vacuum characterized by a dimensionless parameter ϵ. The usual ϕ 4 model is recovered for ϵ = 0.

Bunching and Non-Bunching at Kink Points of the Swedish Tax schedule [PDF]
The compensated taxable income elasticity at a given income level is proportional to the number of individuals who bunch at a convex kink point. This holds true even in the presence of optimization frictions if the jump in marginal tax rates is suciently

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings
Advanced Materials, EarlyView.Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Asymptotic and numerical description of the kink/antikink interaction
Electronic Journal of Differential Equations, 2010 We consider a class of semi-linear wave equations with a small parameter and nonlinearities which provide the equations having exact kink-type solutions.

The Sine-Gordon solitons in nematic liquid crystals under the external electric field
Results in Physics, 2018 In this paper, we study the dynamic equation of molecular motion in nematic liquid crystals when there exists the twisting disturbance of the molecular arrangement under the external electric field.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...
