Chiral Altermagnetic Magnetoelectrics
Advanced Materials, EarlyView.In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Advanced Materials, EarlyView.This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Spin and angular momentum in the nucleon
Physical Review D, 2012 Using the covariant spectator theory (CST), we present the results of a valence quark-diquark model calculation of the nucleon structure function f(x) measured in unpolarized deep inelastic scattering (DIS), and the structure functions g1(x) and g2(x) measured in DIS using polarized beams and targets.

Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3
Advanced Materials, EarlyView.Through precise epitaxial engineering, the cubic and paraelectric KTaO3${\rm KTaO}_3$ is transformed into a robust ferroelectric. By leveraging lattice‐mismatched substrates to apply controlled epitaxial strain, a stable ferroelectric ground‐state is achieved with a transition temperature as high as 475 K, establishing KTaO3${\rm KTaO}_3$ as a highly ...

Physics Letters B, 2016 The claim some years ago, contrary to all textbooks, that the angular momentum of a photon (and gluon) can be split in a gauge-invariant way into an orbital and spin term, sparked a major controversy in the Particle Physics community, exacerbated by the ...

Spin-Textured Neutron Beams with Orbital Angular Momentum
, 2022 We present an experimental protocol that generates spin-textured neutron beams with definite states of orbital angular momentum (OAM) via birefringent neutron spin-polarization devices known as magnetic Wollaston prisms.

Chirality-induced orbital Edelstein effect in an analytically solvable model
Physical Review ResearchChirality-induced spin selectivity (CISS), a phenomenon wherein chiral structures selectively determine the spin polarization of electron currents flowing through the material, has garnered significant attention due to its potential applications in areas

Transverse spin sum rule of the proton
Physics Letters B, 2020 The transversely-polarized state of a proton with arbitrary momentum is not an eigenstate of transverse angular momentum operator. The latter does not commute with the QCD Hamiltonian.

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices
Advanced Materials, EarlyView.We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.
