SUMMARY:BoltzTraP.jl: Thermoelectric transport for the Julia DFT ecosystem

DESCRIPTION:Seebeck coefficient\, electrical conductivity\, and thermal co
 nductivity are key parameters for thermoelectric design. `BoltzTraP.jl` is
  a Julia port of BoltzTraP2\, the standard tool for computing these via th
 e Boltzmann transport equation\, ensuring numerical equivalence with Julia
 -native optimizations. It accepts input from major DFT codes and `DFTK.jl`
 \, enabling an all-Julia workflow from electronic structure to transport p
 roperties. In-memory calculations show over 2x speedup over BoltzTraP2.

SUMMARY:PhoXonic.jl: Unified interface for calculating photonic and phonon
 ic bandgaps with pure Julia - Hiroharu Sugawara

DESCRIPTION:Periodic structures create band gaps that restrict electromagn
 etic and elastic wave propagation. These gaps enable control of light and 
 sound at the wavelength scale. `PhoXonic.jl` is the first pure Julia tool 
 computing both photonic and phononic dispersion relations through a unifie
 d interface using plane wave expansion. It supports 1D\, 2D\, and 3D with 
 dense and sparse solvers\, and includes topological invariant analysis. Re
 sults reproduce published literature.

SUMMARY:Microstructure Simulation in Pure Julia: Phase Fields with CALPHAD
  Coupling - Hiroharu Sugawara

UID:pretalx-juliacon-2026-NMJBP9@pretalx.com
DESCRIPTION:The phase field method simulates microstructure evolution and 
 phase transitions. `PhaseFields.jl` is the first pure Julia package provid
 ing major phase field models with built-in FDM and FEM (via Gridap.jl) and
  adaptive time stepping (DifferentialEquations.jl). It couples with `OpenC
 ALPHAD.jl` for chemical potentials via automatic differentiation from CALP
 HAD databases.  We demonstrate spinodal decomposition\, CALPHAD-driven sol
 idification\, and Stefan problem validation.
