TL;DR: In this article, the pseudotetragonal structure of LCO thin films with different film thickness and unit-cell volume was found to show a significant relaxation of the lattice parameters toward values comparable to those of bulk LCO.

TL;DR: The finite-size scaling analysis in the critical regime based on the Bose-glass model strongly supports the idea of a continuous quantum phase transition and suggests that the transition is governed by quantum percolation.

TL;DR: In this article, measurements of the magnetization, specific heat, resistivity ρ, and magnetoresistivity of single-crystalline Czochralski samples are reported.

TL;DR: In this article, metal-oxide graphene field effect transistors (MOGFETs) were developed on sapphire substrates working at microwave frequencies for monolayers, obtaining a transit frequency up to ∼80 GHz for a gate length of 200 nm and a maximum oscillation frequency of about 3 GHz for this specific sample.

TL;DR: A tentative (p, B, T) phase diagram of CeCoIn(5) is constructed suggesting a quantum critical line in the ( p, B) plane, shielded by superconductivity and extending to negative pressures for B
