Spin-constrained orbital-angular-momentum control in high-harmonic generation
Physical Review Research, 2019 The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscopic polarizations of the driving field.

Global angular momentum generation in heavy-ion reactions within a hadronic transport approach [PDF]
EPJ Web of ConferencesIn this study, we utilize the SMASH transport model to explore the generation of global angular momentum in heavy-ion collisions. Our results corroborate previous models, highlighting a pronounced peak in angular momentum transfer during mid-central ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Dual electromagnetism: helicity, spin, momentum and angular momentum
New Journal of Physics, 2013 The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space. This symmetry underlies the conservation of optical helicity and, as we show here, is closely related to the separation of spin ...

New Journal of Physics, 2022 In this paper, we investigate influences of the charge and angular momentum of a particle around a charged Einstein–Euler–Heisenberg AdS black hole on a Lyapunov exponent, and find spatial regions where the chaos bound is violated.

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object
Advanced Engineering Materials, EarlyView.We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

Dynamical Properties of Magnetized Low-angular-momentum Accretion Flows around a Kerr Black Hole
The Astrophysical JournalAn essential factor for determining the characteristics of an accretion flow is its angular momentum. According to the angular momentum of the flow, semi-analytical analysis suggests various types of accretion solutions. It is critical to test these with

Mapping the transverse spin sum rule in position space
Physics Letters BWe discuss in detail the relativistic spatial distribution of transverse angular momentum, including both orbital and intrinsic spin contributions. Using the quantum phase-space formalism, we begin with the definition of the three-dimensional spatial ...
