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…
Planckian behavior of cuprates at the pseudogap critical point simulated via flat electron-boson spectral density
Hwiwoo Park, Jun H. Park, Jungseek Hwang
Planckian behavior has been recently observed in La1.76Sr0.24CuO4 at the pseudogap critical point. The Planckian behavior takes place in an intriguing quantum metallic state at a q…
Emergence of flat bands and ferromagnetic fluctuations via orbital-selective electron correlations in Mn-based kagome metal
Subhasis Samanta, Hwiwoo Park, Chanhyeon Lee +6
Kagome lattice has been actively studied for the possible realization of frustration-induced two-dimensional flat bands and a number of correlation-induced phases. Currently, the s…
