Supercell altermagnets

Physical Review B
Altermagnets are compensated magnets with unconventional $d$, $g$, and $i$-wave spin order in reciprocal space. So far the search for new altermagnetic candidates has been focused on materials in which the magnetic unit cell is identical to the non-magnetic one, i.e. magnetic structures with zero propagation vector.

Polarons from First Principles, without Supercells [PDF]

Physical Review Letters, 2019
We develop a formalism and a computational method to study polarons in insulators and semi-conductors from first principles. Unlike in standard calculations requiring large supercells, we solve a secular equation involving phonons and electron-phonon matrix elements from density-functional perturbation theory, in a spirit similar to the Bethe-Salpeter ...

The Thermal Modulation of the Bending Wave Bandgap and Waveguide of Phononic Crystal Plates

Crystals
Based on the finite element method, the modulation of the bending wave bandgap and bending waveguide of locally resonant phononic crystal (PnC) plates via a thermal environment is investigated.

Nowcasting of a supercell storm with VERA [PDF]

Meteorology and Atmospheric Physics, 2008
On 13th May 2003, a severe weather event took place in Vienna, located in the eastern part of Austria at the foothills of the Alps. A supercell storm was reported by storm chasers, including a tornado, large hail and flash floods due to heavy precipitation, causing damage to both people and to goods in parts of Vienna downtown, which is a rather rare ...

Compact Supercell Method Based on Opposite Parity for Bragg Fibers [PDF]

, 2003
The supercell- based orthonormal basis method is proposed to investigate the modal properties of the Bragg fibers. A square lattice is constructed by the whole Bragg fiber which is considered a supercell, and the periodical dielectric structure of the ...

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride

Advanced Functional Materials, EarlyView.
This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

Advanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

Strategies of Supercell’s Success

Proceedings of Business and Economic Studies, 2021
Supercell, known as video game company, that is the best at making money, had developed a value of over 10 billion dollars by running only 5 games. All of their games earned more than a billion dollars with over one billion downloads in total. There must be a lot worth studying their strategies.
