Abstract Materials tuned to a quantum critical point display universal scaling properties as a function of temperature T and frequency ω. A long-standing puzzle regarding cuprate superconductors has been the observed power-law dependence of optical

Muon spin rotation/relaxation measurements were performed to investigate magnetic properties of $\mathrm{Fe}{\mathrm{Se}}_{1\ensuremath{-}x}{\mathrm{S}}_{x}$ thin films on $\mathrm{La}\mathrm{Al}{\mathrm{O}}_{3}$. A drastic decrease of the initial as

How a Mott insulator develops into a weakly coupled metal upon doping is a central question to understanding various emergent correlated phenomena. To analyze this evolution and its connection to the high-$T_c$ cuprates, we study the single-particle

The nature of the pseudogap phase of hole-doped cuprate superconductors is still not understood fully. Several experiments have suggested that this phase ends at a critical hole doping level p*, but the nature of the ground state for lower doping is

Method of synthesis of high-quality thin films of Fe chalcogenides, Fe(Te,Se) and FeSe is studied. By investigating the correlation between T c and structural parameters, it is concluded that a compressive strain is introduced on the films on CaF 2 s

The relationship between the superconducting gap and the pseudogap has been the subject of controversies. In order to clarify this issue, we have studied the superconducting gap and pseudogap of the $\text{high}\ensuremath{-}{T}_{c}$ superconductor $

The terahertz (THz) conductivity of FeSe 0.5 Te 0.5 (‘11’-type) and Co-doped BaFe 2 As 2 (‘122’-type) thin films are investigated. For ‘11’-type, the frequency dependence of the complex conductivity can be understood as that of BCS-type s

We study microwave surface impedance measurements of LiFeAs, LiFe(As,P) and FeSe1−xTex single crystals. The in-plane penetration depths of LiFeAs and LiFe(As,P) depend on temperature exponentially at low temperatures, which is a strong indication t

The Hall effect is investigated in thin-film samples of iron-chalcogenide superconductors in detail. The Hall coefficient (RH) of FeTe and Fe(Se1-xTex) exhibits a similar positive value around 300 K, indicating that the high-temperature normal state
