On the difficulty of deciding asymptotic stability of cubic homogeneous vector fields [PDF]

2012 American Control Conference (ACC), 2011
It is well-known that asymptotic stability (AS) of homogeneous polynomial vector fields of degree one (i.e., linear systems) can be decided in polynomial time e.g. by searching for a quadratic Lyapunov function.

Cubic planar vector fields with high local cyclicity

São Paulo Journal of Mathematical Sciences
Abstract In this paper, we present two new one-parameter families of cubic systems exhibiting twelve small-amplitude limit cycles for exceptional parameter values.

Optical solitons and modulation instability for Cubic–quartic Fokas–Lenells equation

Partial Differential Equations in Applied Mathematics, 2022

The family of cubic differential systems with two real and two complex distinct infinite singularities and invariant straight lines of the type $(3,1,1,1)$

Electronic Journal of Qualitative Theory of Differential Equations, 2023
In this article we consider the class $\textbf{CSL}_7^{2r2c \infty}$ of non-degenerate real planar cubic vector fields, which possess two real and two complex distinct infinite singularities and invariant straight lines of total multiplicity 7, including

Proca theory from the spinning worldline

Journal of High Energy Physics, 2022
We obtain Proca field theory from the quantisation of the N $$ \mathcal{N} $$ = 2 supersymmetric worldline upon supplementing the graded BRST-algebra with an extra multiplet of oscillators.

Bulk locality and gauge invariance for boundary-bilocal cubic correlators in higher-spin gravity

Journal of High Energy Physics, 2022
We consider type-A higher-spin gravity in 4 dimensions, holographically dual to a free O(N) vector model. In this theory, the cubic correlators of higher-spin boundary currents are reproduced in the bulk by the Sleight-Taronna cubic vertex.

Observation of the Chiral Soliton Lattice above Room Temperature

Advanced Physics Research, 2023
Magnetic chiral soliton lattices (CSLs) emerge from the helical phase in chiral magnets when magnetic fields are applied perpendicular to the helical propagation vector, and they show great promise for next‐generation magnetic memory applications.

Propagating backward-volume spin waves in epitaxial Fe films

AIP Advances, 2022
The propagation characteristics of backward-volume magnetostatic spin-waves in epitaxial Fe(001) films were studied by frequency-domain and time-domain spin-wave propagation spectroscopies using a vector network analyser.
