, 2001 Following our recent conjecture to model the phenomenona of antiferromagnetism and superconductivity by quantum symmetry groups, we propose in the present note three toy models, namely, one based on SO_{q}(3) the other two constructed with the SO_{q}(4 ...

Modelling optimal ligninolytic activity during plant litter decomposition
New Phytologist, Volume 243, Issue 3, Page 866-880, August 2024.Summary A large fraction of plant litter comprises recalcitrant aromatic compounds (lignin and other phenolics). Quantifying the fate of aromatic compounds is difficult, because oxidative degradation of aromatic carbon (C) is a costly but necessary endeavor for microorganisms, and we do not know when gains from the decomposition of aromatic C outweigh ...

Induced Gravity in Superfluid 3He [PDF]
, 1997 The gapless fermionic excitations in superfluid 3He-A have the "relativistic" spectrum close to the gap nodes. This allowed us to model the modern cosmological scenaria of baryogenesis and magnetogenesis.

Classical and quantum theory of fluctuations for many‐particle systems out of equilibrium
Contributions to Plasma Physics, Volume 64, Issue 5, June 2024.Abstract Correlated classical and quantum many‐particle systems out of equilibrium are of high interest in many fields, including dense plasmas, correlated solids, and ultracold atoms. Accurate theoretical description of these systems is challenging both, conceptionally and with respect to computational resources.

Lorentz violation and Condensed Matter Physics [PDF]
, 2017 We present heuristic arguments that hint to a possible connection of Lorentz violation with observed phenomenon in condensed matter physics. Various references from condensed matter literature are cited where operators in the Standard Model Extension ...

Tooling in Spark Plasma Sintering Technology: Design, Optimization, and Application
Advanced Engineering Materials, Volume 26, Issue 5, March 2024.The review highlights all aspects of tooling in spark plasma sintering (SPS) technology starting from basic configuration to design adapted to the manufacturing of complex‐shaped parts. Modeling and optimization are essential issues in SPS tooling design. Upscaling and industrialization of SPS require multiple die tooling.

Exotic galilean symmetry and non-commutative mechanics [PDF]
, 2010 Some aspects of the "exotic" particle, associated with the two-parameter central extension of the planar Galilei group are reviewed. A fundamental property is that it has non-commuting position coordinates.

Electronic structure of periodic curved surfaces -- topological band structure
, 2001 Electronic band structure for electrons bound on periodic minimal surfaces is differential-geometrically formulated and numerically calculated. We focus on minimal surfaces because they are not only mathematically elegant (with the surface characterized ...
