Crossover between liquid-like and gas-like behaviour in CH4 at 400 K

D. Smith, M. A. Hakeem, P. Parisiades +10

We report experimental evidence for a crossover between a liquid-like state and a gas-like state in fluid methane (CH4). This crossover is observed in all of our experiments, up to…

High-pressure behavior of superconducting boron-doped diamond

Mahmoud Abdel-Hafiez, Dinesh Kumar, R. Thiyagarajan +8

This work investigates the high-pressure structure of freestanding superconducting ( $T_{c}$ = 4.3\,K) boron doped diamond (BDD) and how it affects the electronic and vibrational pr…

Infrared probe of the gap evolution across the phase diagram of Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$

B. Xu, Y. M. Dai, H. Xiao +4

We measured the optical conductivity of superconducting single crystals of Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ with $x$ ranging from 0.40 (optimal doping, $T_{c} = 39$ K) down to 0.20…

Signature of multigap nodeless superconductivity in fluorine-doped NdFeAsO

A. Adamski, C. Krellner, M. Abdel-Hafiez

We investigate the temperature dependence of the lower critical field $H_{c 1} (T)$ , the field at which vortices penetrate into the sample, of a high-quality fluorine-doped NdFeAsO s…

Separation of Electron and Hole Dynamics in the Semimetal LaSb

F. Han, J. Xu, A. S. Botana +8

We report investigations on the magnetotransport in LaSb, which exhibits extremely large magnetoresistance (XMR). Foremost, we demonstrate that the resistivity plateau can be expla…

Universal linear-temperature resistivity: possible quantum diffusion transport in strongly correlated superconductors

Tao Hu, Yinshang Liu, Hong Xiao +2

The strongly correlated electron fluids in high temperature cuprate superconductors demonstrate an anomalous linear temperature ( $T$ ) dependent resistivity behavior, which persists…
