Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures
Journal of Raman Spectroscopy, EarlyView.A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO2$$ {}_2 $$ and the v2$$ {v}_2 $$ mode of CH4$$ {}_4 $$. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH4$$ {}_4 $$ and CO2$$ {}_2 $$ spectra in a diffusion flame ...

Minimal eclectic flavor group Q 8 ⋊ S 3 and neutrino mixing
Journal of High Energy PhysicsWe perform a comprehensive analysis of the minimal eclectic flavor group Q 8 ⋊ S 3 which is isomorphic to GL(2, 3), and all its irreducible representations are induced from the irreducible representations of Q 8 and S 3.

Induced Representation Method in the Theory of Electron Structure and Superconductivity
Advances in Mathematical Physics, 2019 It is shown that the application of theorems of induced representations method, namely, Frobenius reciprocity theorem, transitivity of induction theorem, and Mackey theorem on symmetrized squares, makes simplifying standard techniques in the theory of ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities
Laser &Photonics Reviews, EarlyView.The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Irreducible Representations of Witten's Deformations ofU(sl2)
, 1999 Using E. Witten's approach based on duality in conformal field theory, one can obtain a 7-parameter family of deformations ofU(sl2) (called the “Witten's Deformations”).

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, EarlyView.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

Weyl multiplet structure of QCD
Physics Letters BWe consider Weyl group symmetric structure of SU(3) quantum chromodynamics (QCD) with one flavor quark. It has been demonstrated that the Weyl group as a finite color subgroup of SU(3) provides an intrinsic color symmetry of quark and gluon fields on the

Modular irreducible representations of the symmetric group as linear codes
, 2004 We describe a particularly easy way of evaluating the modular irreducible matrix representations of the symmetric group. It shows that Specht’s approach to the ordinary irreducible representations, along Specht polynomials, can be unified with Clausen’s ...

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14
Mathematische Nachrichten, EarlyView.ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Products and symmetrized powers of irreducible representations of SO*(2n)
, 1998 The calculation of branching rules, tensor products and plethysms of the infinite-dimensional harmonic series unitary irreducible representations of the non-compact group is considered and the duality between and Sp(2k) exploited.
