Whittaker categories of quasi-reductive Lie superalgebras and principal finite W-superalgebras
Chih-Whi Chen, Shun-Jen Cheng
We study the Whittaker category of the Lie superalgebra for an arbitrary character of the even subalgebra of the nilpotent radical associated with…
Whittaker categories of quasi-reductive Lie superalgebras and quantum symmetric pairs
Chih-Whi Chen, Shun-Jen Cheng
We show that, for an arbitrary quasi-reductive Lie superalgebra with a triangular decomposition and a character of the nilpotent radical, the associated Backelin functor …
Whittaker categories, properly stratified categories and Fock space categorification for Lie superalgebras
Chih-Whi Chen, Shun-Jen Cheng, Volodymyr Mazorchuk
We study various categories of Whittaker modules over a type I Lie superalgebra realized as cokernel categories that fit into the framework of properly stratified categories. These…
Inherently high valley polarizations of momentum-forbidden dark excitons in transition-metal dichalcogenide monolayers
Ping-Yuan Lo, Guan-Hao Peng, Wei-Hua Li +2
High degree of valley polarization of optically active excitons in transition-metal dichalcogenide monolayers (TMD-MLs) is vital in valley-based photonic applications but known to…
Blocks and characters of -modules of non-integral weights
Chih-Whi Chen, Shun-Jen Cheng, Li Luo
We classify blocks in the BGG category of modules of non-integral weights for the exceptional Lie superalgebra . We compute the characters for tilting modules of…
Symmetry governed valley-pseudospin textures of the full-zone excitonic bands of transition-metal dichalcogenide monolayers
Ping-Yuan Lo, Guan-Hao Peng, Wei-Hua Li +2
Preserving a high degree of valley polarization of excitons in photo-excited transition-metal dichalcogenide monolayers (TMD-MLs) is desirable for the valley-based photonic applica…
