Does the glory have a simple explanation?.

Optics letters

Nussenzveig HM.
PMID: 18026452
Opt Lett. 2002 Aug 15;27(16):1379-81. doi: 10.1364/ol.27.001379.

The explanation for the meteorological glory provided by the complex angular momentum theory is revisited in response to comments that a simpler physical picture would be desirable. New results that confirm the tunneling origin of the glory and the...

Experimental observation of three-color optical quantum correlations.

Optics letters

Cassemiro KN, Villar AS, Valente P, Martinelli M, Nussenzveig P.
PMID: 17308605
Opt Lett. 2007 Mar 15;32(6):695-7. doi: 10.1364/ol.32.000695.

Quantum correlations among bright pump, signal, and idler beams produced by an optical parametric oscillator, all with different frequencies, are experimentally demonstrated. We show that the degree of entanglement between signal and idler fields is improved by using information...

Tunable squeezing using coupled ring resonators on a silicon nitride chip.

Optics letters

Dutt A, Miller S, Luke K, Cardenas J, Gaeta AL, Nussenzveig P, Lipson M.
PMID: 26766679
Opt Lett. 2016 Jan 15;41(2):223-6. doi: 10.1364/OL.41.000223.

We demonstrate continuous tuning of the squeezing-level generated in a double-ring optical parametric oscillator by externally controlling the coupling condition using electrically controlled integrated microheaters. We accomplish this by utilizing the avoided crossing exhibited by a pair of coupled...

Beyond spectral homodyne detection: complete quantum measurement of spectral modes of light.

Physical review letters

Barbosa FA, Coelho AS, Cassemiro KN, Nussenzveig P, Fabre C, Martinelli M, Villar AS.
PMID: 24289670
Phys Rev Lett. 2013 Nov 15;111(20):200402. doi: 10.1103/PhysRevLett.111.200402. Epub 2013 Nov 14.

Spectral homodyne detection, a widely used technique for measuring quantum properties of light beams, cannot retrieve all the information needed to reconstruct the quantum state of spectral field modes. We show that full quantum state reconstruction can be achieved...

Quantum Noise Correlations of an Optical Parametric Oscillator Based on a Nondegenerate Four Wave Mixing Process in Hot Alkali Atoms.

Physical review letters

Guerrero AM, Nussenzveig P, Martinelli M, Marino AM, Florez HM.
PMID: 32909800
Phys Rev Lett. 2020 Aug 21;125(8):083601. doi: 10.1103/PhysRevLett.125.083601.

We present the first measurement of two-mode squeezing between the twin beams produced by a doubly resonant optical parameter oscillator (OPO) in an above threshold operation based on parametric amplification by nondegenerate four wave mixing with rubidium (^{85}Rb). We...

STAR Protoc. 2021 Jan 21;2(1):100283. doi: 10.1016/j.xpro.2020.100283. eCollection 2021 Mar 19.

The elastic properties of cell membranes, particularly the membrane tension and bending modulus, are known to be key regulators of cellular functions. Here, we present a correlative and integrated tool based on optical tweezers and scanning electron microscopy to...

Three-color entanglement.

Science (New York, N.Y.)

Coelho AS, Barbosa FA, Cassemiro KN, Villar AS, Martinelli M, Nussenzveig P.
PMID: 19762598
Science. 2009 Nov 06;326(5954):823-6. doi: 10.1126/science.1178683. Epub 2009 Sep 17.

Entanglement is an essential quantum resource for the acceleration of information processing as well as for sophisticated quantum communication protocols. Quantum information networks are expected to convey information from one place to another by using entangled light beams. We...
