Negative longitudinal magnetoresistance in the density wave phase of Y$_2$Ir$_2$O$_7$

, 2018
The ground state of nanowires of single crystalline Pyrochlore Y$_2$Ir$_2$O$_7$ is a density wave. Application of a {\it transverse} magnetic field increases the threshold electric field for the collective de-pinning of the density wave state at low ...

Large temperature dependence of the Casimir force at the metal-insulator transition

, 2008
The dependence of the Casimir force on material properties is important for both future applications and to gain further insight on its fundamental aspects. Here we derive a general theory of the Casimir force for low-conducting compounds, or poor metals.
