Nonlinearity-Induced Multiplexed Optical Trapping and Manipulation with Femtosecond Vector Beams

, 2018
Optical trapping and manipulation of atoms, nanoparticles, and biological entities are widely employed in quantum technology, biophysics, and sensing. Single traps are typically achieved with linearly polarized light, while vortex beams form rotationally

Ancient and Current Chaos Theories [PDF]

Interdisciplinary Description of Complex Systems, 2006
Chaos theories developed in the last three decades have made very important contributions to our understanding of dynamical systems and natural phenomena. The meaning of chaos in the current theories and in the past is somewhat different from each other.

Quantum Half and Full Spinning Operator-Based Nonlinear Confusion Component

IEEE Access, 2021
The structure of a substitution box (S-box) is one of the principal ideas of the modern encryption techniques. The security of a modern encryption algorithm highly depends on its nonlinear confusion component.

A Nonlinear Wave Equation with Jumping Nonlinearity

Discrete and Continuous Dynamical Systems, 1998
The authors study multiplicity of solutions \(u(x,t)\) for a piecewise linear perturbation of the one-dimensional wave operator \(u_{tt}-u_{xx}\) under Dirichlet boundary condition on the interval \((-{\pi\over 2}, {\pi\over 2})\) and periodic condition on \(t\), that is \[ \begin{cases} u_{tt}-u_{xx}+g (u)=f(x,t) \text{ in }\left(-{\pi\over 2}, {\pi ...
