Temporal Associations Between Polarimetric Updraft Proxies and Signatures of Inflow and Hail in Supercells

Remote Sensing
Recurring polarimetric radar signatures in supercells include deep and persistent differential reflectivity (ZDR) columns, hail inferred in low-level scans, and the ZDR arc signature.

Non-Abelian Hyperbolic Band Theory from Supercells. [PDF]

Physical Review Letters, 2023
Wave functions on periodic lattices are commonly described by Bloch band theory. Besides Abelian Bloch states labeled by a momentum vector, hyperbolic lattices support non-Abelian Bloch states that have so far eluded analytical treatments.

Effective phonon dispersion and low field transport in AlxGa1−xN alloys using supercells: An ab initio approach [PDF]

Journal of Applied Physics
To investigate the transport properties in random alloys, it is important to model the alloy disorder using supercells. Although computationally expensive, the local disorder in the system is accurately captured as translational symmetry that is imposed ...

Buried moiré supercells through SrTiO_{3} nanolayer relaxation [PDF]

Physical Review Research, 2021
We identified a highly ordered moiré lattice at the buried SrTiO_{3} (STO)-(La,Sr)(Al,Ta)-oxide (LSAT) interface by high-resolution x-ray diffraction reciprocal space mapping.

The minimal supercells approach for ab-initio calculation in 2D alloying transition metal dichalcoginides with special quasi-random structure

Materials Research Express, 2020
Density functional theory (DFT) is used to investigate MoS _2 and WS _2 monolayers, which are direct bandgap semiconductors. We study alloying between MoS _2 and WS _2 by using special quasi-random structure (SQS), through a comparison of the computed ...

Generation of almost rectangular, square, and hexagonal two-dimensional supercells

Science and Technology of Advanced Materials: Methods
This study outlines procedures to make 2D supercells, of arbitrary crystals and orientations, with a given size and are almost commensurate with rectanglar, square, or hexagonal lattices.

Supercell convective environments in Spain based on ERA5: hail and non-hail differences [PDF]

Weather and Climate Dynamics, 2022
Severe convective storms, in particular supercells, are occasionally responsible for a large number of property losses and damage in Spain. This paper aims to study the synoptic configurations and pre-convective environments in a dataset of 262 ...

Supercells in Environments with Atypical Hodographs

Weather and Forecasting, 2011
Abstract An unusual severe weather event with supercell thunderstorms developed across portions of northern Arizona in the midst of the warm-season North American monsoon—a regime characteristically dominated by a subtropical upper-level high over the southwestern United States.
