An inversion problem for optical spectrum data via physics-guided machine learning
Hwiwoo Park, Jun H. Park, Jungseek Hwang
We propose the regularized recurrent inference machine (rRIM), a novel machine-learning approach to solve the challenging problem of deriving the pairing glue function from measure…

Bosonic spectrum of a correlated multiband system, BaFe1.80Co0.20As2, obtained via infrared spectroscopy
Chandan Kumar Panda, Hong Gu Lee, Hwiwoo Park +3
We investigated a single crystal BaFe(2-x)CoxAs2 (Co-doped BaFe2As2: Co-doped Ba122) with x = 0.20 using infrared spectroscopy. We obtained the bosonic spectrum from the measured s…

Fermi liquid-like behaviour of cuprates in the pseudogap phase simulated via T-dependent electron-boson spectral density
Hwiwoo Park, Jungseek Hwang
We investigated the temperature- and frequency-dependent optical scattering rates in the pseudogap phase of cuprates using model pseudogap and electron-boson spectral density (EBSD…
