Compact spin-valley-locked perovskite emission
Nature Materials, 2023Circularly polarized light sources with free-space directional emission play a key role in chiroptics1, spintronics2, valleytronics3 and asymmetric photocatalysis4. However, conventional approaches fail to simultaneously realize pure circular polarization, high directionality and large emission angles in a compact emitter.

Stochastic Dynamics of Compact Spins: Ergodicity and Irreducibility
Acta Applicandae Mathematica, 2000Let \(M\) be a compact Riemannian manifold and \(Z^d\) an integer lattice. The semigroup \(T_t =e^{-tH_\mu}\) in \(L^2 (\mu)\) where \(\mu\) is a Gibbs measure on \(M^Z{^d}\) and \(H_\mu\) is the corresponding Dirichlet operator is studied. The main result of the paper is the equivalence of irreducibility of the Dirichlet form associated with \(\mu ...

Compact Spinning: A Critical Review
Textile Engineering, 2003Compact spinning is a novel concept generated through re-engineering of established ring spinning process by attaching a pneumatic zone to existing ring spinning machine. Compact spinning achieves a remarkable improvement in yarn quality and yarn structure through better utilization of fibre properties.

Applied Physics Letters, 2016
In this letter, we propose and experimentally demonstrate a compact photonic spin filter formed by integrating a Pancharatnam-Berry phase lens (focal length of ±f) into a conventional plano-concave lens (focal length of −f). By choosing the input port of the filter, photons with a desired spin state, such as the right-handed component or the left ...

Runtime Efficient State Compaction in Spin
1999Spin is a verification system that can detect errors automatically by exploring the reachable state space of a system. The efficiency of verifiers like Spin depends crucially on the technique used for the representation of states. A number of recent proposals for more compact representations reduce the memory requirements, but cause a considerable ...

The Effect of Spin-Orbit Coupling and Spin-Spin Coupling of Compact Binaries on Chaos*
Communications in Theoretical Physics, 2015Abstract There are spin-orbit interaction and spin-spin interaction in a generic post-Newtonian Lagrangian formulation of comparable mass spinning compact binaries. The spin-orbit coupling or the spin-spin coupling plays a quite important role in changing the evolution of the system and may sometime cause chaotic behavior. How do the two

IEEE Journal of Quantum Electronics, 1967
An alternative to ring lasers for spin-rate sensing is proposed, which is less sensitive but potentially more compact. It consists of a two-mirror CW laser supporting a higher-order TEM pl Laguerre-Gaussian mode of the ring type, isolated by means of a uniform annular distribution of net gain.

Second order spin effects in the spin precession of compact binaries
Physical Review D, 2012We present the continuation of J. Maj\'ar [Phys. Rev. D 80, 104028 (2009)] to solve the instantaneous spin precession equations for the spin-orbit, spin-spin, and quadrupole-monopole contributions. In this paper we present the solution of the quadrupole-monopole contributions to the precession equations.
