Physical review letters

Mazor Y, Steinberg BZ.
PMID: 24785040
Phys Rev Lett. 2014 Apr 18;112(15):153901. doi: 10.1103/PhysRevLett.112.153901. Epub 2014 Apr 18.

Confluent with the single dimension of time, breach of time-reversal symmetry is usually perceived as a one-dimensional concept. In its ultimate realization-the one-way guiding device-it allows optical propagation in one direction, say +z, and forbids it in the opposite...

Narrow-band microcavity waveguides in photonic crystals.

Journal of the Optical Society of America. A, Optics, image science, and vision

Boag A, Steinberg BZ.
PMID: 11688870
J Opt Soc Am A Opt Image Sci Vis. 2001 Nov;18(11):2799-805. doi: 10.1364/josaa.18.002799.

A novel device, formed by a widely spaced periodic array of defects in a photonic bandgap crystal, is studied with the goal of designing a waveguide with a prescribed narrow bandwidth. Tunneling of radiation between the defect sites allows...

Sensitivity analysis of narrowband photonic crystal filters and waveguides to structure variations and inaccuracy.

Journal of the Optical Society of America. A, Optics, image science, and vision

Steinberg BZ, Boag A, Lisitsin R.
PMID: 12542326
J Opt Soc Am A Opt Image Sci Vis. 2003 Jan;20(1):138-46. doi: 10.1364/josaa.20.000138.

Photonic crystal microcavities, formed by local defects within an otherwise perfectly periodic structure, can be used as narrowband optical resonators and filters. The coupled-cavity waveguide (CCW) is a linear array of equally spaced identical microcavities. Tunneling of light between...

Conditional-phase switch at the single-photon level.

Physical review letters

Resch KJ, Lundeen JS, Steinberg AM.
PMID: 12144421
Phys Rev Lett. 2002 Jul 15;89(3):037904. doi: 10.1103/PhysRevLett.89.037904. Epub 2002 Jun 28.

We present an experimental realization of a two-photon conditional phase switch, related to the " c-phis;" gate of quantum computation. This gate relies on quantum interference between photon pairs and generates entanglement between two optical modes through the process...

Super-resolving phase measurements with a multiphoton entangled state.

Nature

Mitchell MW, Lundeen JS, Steinberg AM.
PMID: 15141206
Nature. 2004 May 13;429(6988):161-4. doi: 10.1038/nature02493.

Interference phenomena are ubiquitous in physics, often forming the basis of demanding measurements. Examples include Ramsey interferometry in atomic spectroscopy, X-ray diffraction in crystallography and optical interferometry in gravitational-wave studies. It has been known for some time that the...

Detection of antibodies to varicella-zoster virus using a latex agglutination assay.

Clinical and diagnostic virology

Gershon AA, Larussa P, Steinberg S.
PMID: 15566772
Clin Diagn Virol. 1994 Aug;2(4):271-7. doi: 10.1016/0928-0197(94)90051-5.

BACKGROUND: There is a clinical need to have a rapid and sensitive means to identify persons with immunity to varicella-zoster virus (VZV).OBJECTIVES: We evaluated a simple-to-perform assay for detecting antibodies to VZV using a commercial latex agglutination (LA) test,...

Diketopiperazine formation during investigations of amino Acid racemization in dipeptides.

Science (New York, N.Y.)

Steinberg S, Bada JL.
PMID: 17794841
Science. 1981 Jul 31;213(4507):544-5. doi: 10.1126/science.213.4507.544.

The formation of diketopiperazines from the dipeptides isoleucylglycine and glycylisoleucine was investigated at 132 degrees C over the pH range approximately 2 to 10. At pH 6.2, approximately 50 percent of the original dipeptides were converted to the diketopiperazines...

Observation of high-order quantum resonances in the kicked rotor.

Physical review letters

Kanem JF, Maneshi S, Partlow M, Spanner M, Steinberg AM.
PMID: 17359095
Phys Rev Lett. 2007 Feb 23;98(8):083004. doi: 10.1103/PhysRevLett.98.083004. Epub 2007 Feb 23.

Quantum resonances in the kicked rotor are characterized by a dramatically increased energy absorption rate, in stark contrast to the momentum localization generally observed. These resonances occur when the scaled Planck's constant Planck's [over ]=r/s 4pi, for any integers...

Digital beamforming in ultrasound.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Steinberg BD.
PMID: 18267687
IEEE Trans Ultrason Ferroelectr Freq Control. 1992;39(6):716-21. doi: 10.1109/58.165556.

The effects on array gain and sidelobe level of a practical digital beamforming (DBF) processor under the wideband conditions typical of ultrasound is discussed. It is concluded that a relatively simple design that replaces each analog delay line with...

Wavefront amplitude distortion and image sidelobe levels. I. Theory and computer simulations.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Zhu Q, Steinberg BD.
PMID: 18263242
IEEE Trans Ultrason Ferroelectr Freq Control. 1993;40(6):747-53. doi: 10.1109/58.248219.

The quality of an imaging system is degraded by propagation anomalies that distort wavefronts propagating through the medium. Adaptive phase-deaberration algorithms compensate for phase errors in the wavefront. The algorithms suffer, however, when the wavefront is also significantly distorted....
