Fiber-optic ferrule-top nanomechanical resonator with multilayer graphene film.

Optics letters

Ma J, Jin W, Xuan H, Wang C, Ho HL.
PMID: 25121870
Opt Lett. 2014 Aug 15;39(16):4769-72. doi: 10.1364/OL.39.004769.

Compact ferrule-top nanomechanical resonators with multilayer graphene (MLG) diaphragms as vibrating elements are demonstrated. The resonators comprise a suspended MLG film supported by a ceramic ferrule with a bore diameter of ∼125 μm. The mechanical resonance of the graphene...

We present in this paper a quantitative study of an effect, in which a low-energy free electron is captured and violently accelerated to GeV final kinetic energy by a stationary extra-high-intensity laser beam (Q0 identical witheE/m(e)omegac greater, similar100). The...

Comment on "Vacuum electron acceleration by coherent dipole radiation".

Physical review. E, Statistical, nonlinear, and soft matter physics

Troha et al. [Phys. Rev. E 60, 926 (1999)] put forward a generalized Lawson-Woodward theorem in the study of laser accelerations. We point out that one of the assumptions used in their proof does not stand on a solid...

Two-component Bose-Einstein condensates with a large number of vortices.

Physical review letters

Mueller EJ, Ho TL.
PMID: 12005671
Phys Rev Lett. 2002 May 06;88(18):180403. doi: 10.1103/PhysRevLett.88.180403. Epub 2002 Apr 19.

We consider the condensate wave function of a rapidly rotating two-component Bose gas with an equal number of particles in each component. If the interactions between like and unlike species are very similar (as occurs for two hyperfine states...

Rapidly rotating fermi gases.

Physical review letters

Ho TL, Ciobanu CV.
PMID: 11082618
Phys Rev Lett. 2000 Nov 27;85(22):4648-51. doi: 10.1103/PhysRevLett.85.4648.

We show that the density profile of a Fermi gas in rapidly rotating potential will develop prominent features reflecting the underlying Landau-level-like energy spectrum. Depending on the aspect ratio of the trap, these features can be a sequence of...
