Quantum-Coherence-Enhanced Surface Plasmon Amplification by Stimulated Emission of Radiation
Konstantin E. Dorfman, Pankaj K. Jha, Dmitri V. Voronine +3
We investigate surface plasmon amplification in a silver nanoparticle coupled to an externally driven three-level gain medium, and show that quantum coherence significantly enhance…
Achieving a Strongly Temperature-Dependent Casimir Effect
Alejandro W. Rodriguez, David Woolf, Alexander P. McCauley +3
We propose a method of achieving large temperature sensitivity in the Casimir force that involves measuring the stable separation between dielectric objects immersed in fluid. We s…
Non-touching nanoparticle diclusters bound by repulsive and attractive Casimir forces
Alejandro W. Rodriguez, Alexander P. McCauley, David Woolf +3
We present a scheme for obtaining stable Casimir suspension of dielectric nontouching objects immersed in a fluid, validated here in various geometries consisting of ethanol-separa…
Measurements of the Casimir-Lifshitz force in fluids: the effect of electrostatic forces and Debye screening
J. N. Munday, Federico Capasso, V. Adrian Parsegian +1
In this work, we present detailed measurements of the Casimir-Lifshitz force between two gold surfaces (a sphere and a plate) immersed in ethanol and study the effect of residual e…
Stable suspension and dispersion-induced transitions from repulsive Casimir forces between fluid-separated eccentric cylinders
Alejandro W. Rodriguez, J. N. Munday, J. D. Joannopoulos +3
Using an exact numerical method for finite nonplanar objects, we demonstrate a stable mechanical suspension of a silica cylinder within a metallic cylinder separated by ethanol, vi…
Reply to "Comment on 'Precision measurement of the Casimir-Lifshitz force in a fluid'"
J. N. Munday, Federico Capasso
We have reviewed the Comment of Geyer et al. [arXiv:0708.1548] concerning our recent work [Phys. Rev. A 75, 060102 (R) (2007)], and while we disagree with their criticisms, we ackn…
