Electron-boson spectral density of LiFeAs obtained from optical data
J. Hwang, J. P. Carbotte, B. H. Min +2
We analyze existing optical data in the superconducting state of LiFeAs at 4 K, to recover its electron-boson spectral density. A maximum entropy technique is employed to ext…
Effect of a magnetic field on the quasiparticle recombination in superconductors
Xiaoxiang Xi, J. Hwang, C. Martin +4
Quasiparticle recombination in a superconductor with an s-wave gap is typically dominated by a phonon bottleneck effect. We have studied how a magnetic field changes this recombina…
Optical Self Energy in Graphene due to Correlations
J. Hwang, J. P. F. LeBlanc, J. P. Carbotte
In highly correlated systems one can define an optical self energy in analogy to its quasiparticle (QP) self energy counterpart. This quantity provides useful information on the na…
Doping and temperature-dependent optical properties of oxygen-reduced BaTiO3-d
J. Hwang, T. Kolodiazhnyi, J. Yang +1
We report on optical properties of reduced BaTiO3-d at different doping levels including insulating and metallic samples. In all the samples, including metallic one, we observe str…
Spin Dynamics in Cuprates: Optical Conductivity of HgBa2CuO4
J. Yang, J. Hwang, E. Schachinger +5
The electron-boson spectral density function I^2ChiOmega responsible for carrier scattering of the high temperature superconductor HgBa2CuO4 (Tc = 90 K) is calculated from new data…
Fermi surface arcs and the infrared conductivity of underdoped YBaCuO
J. Hwang, J. P. Carbotte, T. Timusk
We reanalyze the data on the in-plane far infrared conductivity of underdoped orthoII YBaCuO (YBCO) in terms of a model in which a pseudogap opens on…
