Journal ArticleDOI
Heat capacity of diluted cerium magnesium nitrate and its potential for the production of very low temperatures
TL;DR: In this article, the magnetic heat capacity of pure cerium magnesium nitrate (CMN) and La-diluted CMN has been investigated and it has been shown that it may be possible to use the diluted salt as a refrigerant to 0.7 mK.
Journal ArticleDOI
Production of 1s quadrupole-orthoexciton polaritons in Cu 2 O by two-photon pumping
Journal ArticleDOI
Periodic magnetization instabilities in a superconducting Nb film with a square lattice of Ni dots
TL;DR: In this article, a superconducting Nb film perforated by a square lattice of Ni dots exhibits quasiperiodic instabilities below 4 K, with a field-dependent period equal to the first, second, or third matching fields.
Journal ArticleDOI
Force measurement on microspheres in an optical standing wave
TL;DR: In this paper, the authors measured the optical forces on isolated particles trapped in an optical lattice generated by the interference of two coherent laser beams and developed an approach that allows tunable, size-dependent force selection of a subset of particles from an ensemble containing mixed particles.
Journal ArticleDOI

TL;DR: In this paper, a large second-order nonlinear optical response was observed in silicon carbide thin films deposited by pulsed laser ablation on sapphire and fused silica substrates; films on both substrates were uniform and optically transparent but exhibited distinct orientations.
