Chiroferromagnetic Quantum Dots for Chiroptical Synapse (ChiropS)
Advanced Materials, EarlyView.Chiroptical activity is enhanced by up to 0.003 in the g‐factor through the induction of ferromagnetism in quantum dots. A chiroptical neuromorphic synapse, composed of chiroferromagnetic quantum dots, generates different synaptic weights from multiple wavelengths and circularly polarized light.

Existence of a ground-state solution for a quasilinear Schrödinger system
Frontiers in PhysicsIn this paper, we consider the following quasilinear Schrödinger system.−Δu+u+k2Δ|u|2u=2αα+β|u|α−2u|v|β,x∈RN,−Δv+v+k2Δ|v|2v=2βα+β|u|α|v|β−2v,x∈RN,where k < 0 is a real constant, α > 1, β > 1, and α + β < 2*.

Canonical transformations of linear Hamiltonian systems [PDF]
E3S Web of ConferencesIn this paper we consider the linear Hamiltonian systems of differential equations. We explore the normalization of a non-singular Hamiltonian matrix. We solve a system of matrix equations to find the generating function of the canonical transformation ...

Linear port-Hamiltonian systems are generically controllable [PDF]
arXiv, 2021 The new concept of relative generic subsets is introduced. It is shown that the set of controllable linear finite-dimensional port-Hamiltonian systems is a relative generic subset of the set of all linear finite-dimensional port-Hamiltonian systems.

Quantization of noncommutative completely integrable Hamiltonian systems [PDF]
Physics Letters A, v.362 (2007) 138-142, 2006 Integrals of motion of a Hamiltonian system need not be commutative. The classical Mishchenko-Fomenko theorem enables one to quantize a noncommutative completely integrable Hamiltonian system around its invariant submanifold as an abelian completely integrable Hamiltonian system.

Current Control of Spin Helicity and Nonreciprocal Charge Transport in a Multiferroic Conductor
Advanced Materials, EarlyView.A conducting multiferroic state of spin origin with both electronic polarity (P) and magnetization (M) can be controlled and detected by electric current in a high‐temperature helimagnet YMn6Sn6. The underlying concept is the coupling of the electric current with the toroidal moment T∼P×M$\bm{T}\sim \bm{P}\ensuremath{\times{}}\bm{M}$.

Higher Order Hamiltonian Systems with Generalized Legendre Transformation
Mathematics, 2018 The aim of this paper is to report some recent results regarding second order Lagrangians corresponding to 2nd and 3rd order Euler–Lagrange forms. The associated 3rd order Hamiltonian systems are found.

High Sensitivity Spin Defects in Carbon Implanted Diamond
Advanced Optical Materials, EarlyView.Self‐interstitial spin defects in diamond are fabricated in diamond by high energy carbon irradiation. Along with a systematic characterization of their properties, these spin defects demonstrate high sensitivities surpassing previous studies and coherent manipulation of spin states.

Analytical Solution to Normal Forms of Hamiltonian Systems
Mathematical and Computational Applications, 2017 The idea of the normalisation of the Hamiltonian system is to simplify the system by transforming Hamiltonian canonically to an easy system. It is under symplectic conditions that the Hamiltonian is preserved under a specific transformation—the so-called

Advanced Photonics Research, EarlyView.A method is proposed for actively generating Friedrich–Wintgen bound state in the continuum (FW BIC) in a hybrid plasmonic–photonic structure near the commercially important communication wavelength. In addition, interactions between dark and bright modes can further form the FW BIC and support electromagnetically induced transparency‐like with maximum
