About me: Udomsilp Pinsook is a theoretical physicist at Chulalongkorn University whose work bridges fundamental quantum theory and real materials. His research explores how collective excitations—electrons, phonons, and sometimes their special hybrids—govern the emergent behavior of solids: superconductivity, magnetism, and transport in complex materials.

Working within frameworks that span quantum field theory, path integrals, and density-functional theory, he seeks analytic and numerical forms that reveal universal scaling and hidden simplicity beneath apparent complexity.

Here is the list of his digital footprints:

ARPES of Bi2212 interpreted via a particle in a system of dynamic scatterers
🔗 https://arxiv.org/abs/2510.21568

In this work, I propose a new framework to interpret the ARPES spectra of overdoped Bi₂Sr₂CaCu₂O₈₊δ (Bi2212). The analysis treats the photoemitted electron as a particle moving in a system of dynamic scatterers, leading naturally to spectral features described by parabolic cylinder functions. This approach captures the entire peak–dip–hump structure across temperatures—from the superconducting to the pseudogap and normal phases—within a unified mathematical picture. Fitting parameters such as A, C, and EG​ are directly linked to the degree of coherence and the underlying electronic disorder, offering insight into how randomness and pairing interplay in high-Tc cuprates.
