VTICD 2025 brings together researchers, students, and professionals to
advance quantum simulation methods and computational materials design.
Jointly organized by National Yang Ming Chiao Tung University (Taiwan, ROC)
and Hanoi National University of Education (Viet Nam), the workshop features
expert-guided lectures, hands-on tutorials, and collaborative discussions.
This edition also highlights WannierBSE, a practical workflow for excitonic
and optical-spectrum calculations based on Wannier-function interpolation and
the Bethe–Salpeter equation, with a live demonstration and Q&A.

WannierBSE Code
WannierBSE is an efficient computational package for solving the Bethe–Salpeter equation (BSE)
for neutral excitons in 2D materials within the Wannier tight‑binding (WTB) framework, implemented
in the MATLAB (single‑machine) and C++ (parallel) languages.
It constructs electron–hole Coulomb kernels using efficient numerical integration
and cubic‑spline interpolation for speed and precision. Based on first‑principles band structures,
Bloch states, and non‑local dielectric functions (from DFT+GW or macroscopic electromagnetic theory),
WannierBSE enables multiscale simulations of excitonic spectra, dipoles, and light–matter interactions
in hybrid 2D materials under complex dielectric environments.
