Geometric Nonlinearities in Field Theory, Condensed Matter and Analytical Mechanics [PDF]
, 2010 There are two very important subjects in physics: Symmetry of dynamical models and nonlinearity. All really fundamental models are invariant under some particular symmetry groups.

Interaction-induced edge states in anisotropic non-Fermi liquids
Scientific Reports, 2017 We devise an approach to calculation of scaling dimensions of generic operators describing scattering within multi-channel Luttinger liquid. The local impurity scattering in arbitrary configuration of conducting and insulating channels is investigated ...

International Journal of Bifurcation and Chaos, 1997 The objectives and some basic methods of numerical bifurcation analysis are described. Several computational examples are used to illustrate the power as well as the limitations of these techniques. Directions in which further algorithmic and software development is desirable are also discussed.

Biometrika, 1988 The paper presents at first an outline of the basic linear algebra of the classical biplot. Let X be an \(n\times p\) matrix containing numerical information on p variables for each of n samples. The graphical representation of X in a biplot is based on the singular value decomposition \(X=UGV'\), where U and V are \(n\times n\) and \(p\times p ...

Second order nonlinear frequency generation at the nanoscale in dielectric platforms
Advances in Physics: X, 2022 Nonlinear frequency generation at the nanoscale is a hot research topic which is gaining increasing attention in nanophotonics. The generation of harmonics in subwavelength volumes is historically associated with the enhancement of electric fields in the

Nonlinearity and nonclassicality in a nanomechanical resonator [PDF]
, 2015 We address quantitatively the relationship between the nonlinearity of a mechanical resonator and the nonclassicality of its ground state. In particular, we analyze the nonclassical properties of the nonlinear Duffing oscillator (being driven or not) as ...
