Note on the space group selection rule for closed strings on orbifolds

Journal of High Energy Physics, 2019
It is well-known that the space group selection rule constrains the interactions of closed strings on orbifolds. For some examples, this rule has been described by an effective Abelian symmetry that combines with a permutation symmetry to a non-Abelian ...

Modulation of Ionically Generated Space Charge Effects at Hybrid Perovskite and Oxide Interfaces via Surface Modification

Advanced Materials Interfaces
Interfacial space charges significantly influence transport and recombination of charge carriers in optoelectronic devices. Due to the mixed ionic‐electronic conducting properties of halide perovskites, not only electronic effects, but also ionic ...

Temperature and electric field dependence of charge conduction and accumulation in XLPE based on polarization and depolarization current

AIP Advances, 2019
Temperature and electric field are important factors affecting space charge accumulation in high voltage dc (HVDC) cable insulation. Charge conduction and accumulation in XLPE have been studied by correlating the polarization and depolarization processes.

On the charge algebra of causal diamonds in three dimensional gravity

Journal of High Energy Physics
Covariant phase space methods are applied to the analysis of a causal diamond in 2+1-dimensional pure Einstein gravity. It is found that the reduced phase space is parametrized by a family of charges with a dual geometrical interpretation: they are ...

Boundary conditions of warped AdS3 in new massive gravity

Physics Letters B
To satisfy the Cardy formula for Warped AdS3 (WAdS3) solutions in a quadratic ensemble, a specific set of boundary conditions has been proposed in [1]. In this paper, these boundary conditions have been investigated in the three-dimensional new massive ...

Infinite-dimensional hierarchy of recursive extensions for all sub n -leading soft effects in Yang-Mills

Journal of High Energy Physics
Building on our proposal in [1], we present in detail the construction of the extended phase space for Yang-Mills at null infinity, containing the asymptotic symmetries and the charges responsible for sub n -leading soft theorems at all orders.
