Groups with Chernikov conjugacy classes in which Sylow permutability is a transitive relation

Journal of Algebra, 2010
A subgroup $H$ of a group $G$ is called permutable (or quasinormal) if $HK=KH$ for all subgroups $K$ of $G$. A group $G$ is called a PT-group if permutability is a transitive relation. A subgroup $H$ is called S-permutable if $HS=SH$ for every Sylow $p$-subgroup $S$ of $G$ and for each prime $p$.

Finite groups and Lie rings with an automorphism of order $2^n$

, 2015
Suppose that a finite group $G$ admits an automorphism $\varphi $ of order $2^n$ such that the fixed-point subgroup $C_G(\varphi ^{2^{n-1}})$ of the involution $\varphi ^{2^{n-1}}$ is nilpotent of class $c$.

Suppressing Diffusion-Mediated Exciton Annihilation in 2D Semiconductors Using the Dielectric Environment

, 2018
Atomically thin semiconductors such as monolayer MoS2 and WS2 exhibit nonlinear exciton-exciton annihilation at notably low excitation densities (below ~10 excitons/um2 in MoS2).
