The paper,
"Self-consistent Coulomb interactions from constrained dynamical mean-field theory,"
appears in Phys. Rev. B 113, L201116 (2026).
The authors developed a new first-principles computational approach that improves our understanding of how strongly electrons interact in complex materials. By comparing advanced quantum-mechanical calculations with experimental measurements, the approach provides a more reliable description of materials such as Mott insulators, correlated materials, altermagnets, and unconventional superconductors.
These findings will help researchers to study and design next-generation electronic and superconducting materials.
Building on prior research experience at Trinity College Dublin and the Indian Institute of Technology Mandi, Dr. Sihi works on strongly correlated materials using advanced first-principles methods such as DFT+DMFT. His research focuses on electron-phonon coupling, Coulomb interaction estimation, and high-throughput studies of correlated materials.
