Orbitally excited and hybrid mesons from the lattice [PDF]
Physical Review D, 1996 We discuss in general the construction of gauge-invariant non-local meson operators on the lattice. We use such operators to study the $P$- and $D$-wave mesons as well as hybrid mesons in quenched QCD, with quark masses near the strange quark mass. The resulting spectra are compared with experiment for the orbital excitations.

Novel Consequent-Pole Hybrid Excited Machine with Separated Excitation Stator
IEEE Transactions on Industrial Electronics, 2016 A partitioned stator hybrid excited machine is proposed, in which the permanent magnets and field windings are alternately placed on an inner stator separated from the outer stator having armature windings. This machine inherits the features of brushless machines and benefits from better space utilization.

Hybrid and orbitally excited mesons in quenched QCD [PDF]
Nuclear Physics B - Proceedings Supplements, 1998 We use lattice methods to evaluate from first principles the spectrum of hybrid mesons produced by gluonic excitations in quenched QCD with quark masses near the strange quark mass. For the spin-exotic mesons with $J^{PC}=1^{-+},\ 0^{+-}$, and $2^{+-}$ which are not present in the quark model, we determine the lightest state to be $1^{-+}$ with mass of
