The Khovanov-Lauda 2-Category and Categorifications of a Level Two Quantum SL(N) Representation

International Journal of Mathematics and Mathematical Sciences, 2010
We construct 2-functors from a 2-category categorifying quantum sl(n) to 2-categories categorifying the irreducible representation of highest weight 2ωk.

Large N limit of irreducible tensor models: O(N) rank-3 tensors with mixed permutation symmetry

Journal of High Energy Physics, 2018
It has recently been proven that in rank three tensor models, the antisymmetric and symmetric traceless sectors both support a large N expansion dominated by melon diagrams [1].

Irreducible representations of the Poincare parasuperalgebra [PDF]

Journal of Physics A: Mathematical and General, 1995
Summary: We explicitly describe all the irreducible unitary representations of the Poincaré parasuperalgebra, i.e. the parasupersymmetric extension of the Lie algebra of the Poincaré group. This parasuperalgebra includes, as a particular case, the usual Poincaré superalgebra and can serve as the group-theoretical foundation of parasupersymmetric ...

Irreducible representations of finite spin groups

, 2022
In this paper we present a computation (done by the author in 1983) which yields a multiplicity one statement for the irreducible representations of a finite spin group which, in turn, yields the classification of the irreducible representations of a ...

Nonlocal Metaspire: A Scalable Elastic Material Platform With Decoupled Mechanical Modes

Advanced Materials, EarlyView.
Nonlocal Metaspire introduces sequential rotation to realize wider scalability in implementing complex nonlocal couplings in elastic metamaterials while suppressing unintended mode coupling. Numerical results clarify the underlying wave motions, demonstrate mode‐decoupled roton and maxon formation, and support a straightforward extension to higher ...

Ferromagnets from higher SU(N) representations

Nuclear Physics B
We present a general formalism for deriving the thermodynamics of ferromagnets consisting of “atoms” carrying an arbitrary irreducible representation of SU(N) and coupled through long-range two-body quadratic interactions. Using this formalism, we derive

Exciton Radiative Lifetimes in Hexagonal Diamond Ge and SixGe1–x Alloys

Advanced Optical Materials, EarlyView.
Strong room‐temperature photoluminescence reported in hexagonal Ge conflicts with theory predicting a nearly dark band edge. First‐principles calculations of excitonic radiative lifetimes fill a key gap in this debate, showing that pristine hexagonal Ge remains intrinsically weakly emissive, while Si alloying only modestly shortens the lifetime and ...

General cubic interacting vertex for massless integer higher spin fields

Physics Letters B, 2021
We consider a massless higher spin field theory within the BRST approach and construct a general off-shell cubic vertex corresponding to irreducible higher spin fields of helicities s1,s2,s3. Unlike the previous works on cubic vertices, which do not take

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...
