Detecting non-Abelian anyons by charging spectroscopy.

Physical review letters

Ben-Shach G, Laumann CR, Neder I, Yacoby A, Halperin BI.
PMID: 23521280
Phys Rev Lett. 2013 Mar 08;110(10):106805. doi: 10.1103/PhysRevLett.110.106805. Epub 2013 Mar 08.

Observation of non-Abelian statistics for the e/4 quasiparticles in the ν = 5/2 fractional quantum Hall state remains an outstanding experimental problem. The non-Abelian statistics are linked to the presence of additional low energy states in a system with...

Social isolation increases social display after priming in Betta splendens but decreases aggressive readiness.

Behavioural processes

Halperin JR, Dunham DW, Ye S.
PMID: 24924788
Behav Processes. 1992 Dec;28(1):13-31. doi: 10.1016/0376-6357(92)90045-F.

We socially isolated adult, male Siamese fighting fish for 0 to 7 weeks but avoided sensory deprivation, and then measured aggressive display as the fish responded to a series of novel models. Isolates displayed much more strongly than non-isolates...

Oxidative Coupling of Aryl Boron Reagents with sp(3)-Carbon Nucleophiles: The Enolate Chan-Evans-Lam Reaction.

Angewandte Chemie (International ed. in English)

Moon PJ, Halperin HM, Lundgren RJ.
PMID: 26732351
Angew Chem Int Ed Engl. 2016 Jan 26;55(5):1894-8. doi: 10.1002/anie.201510558. Epub 2016 Jan 06.

Reported is a versatile new oxidative method for the arylation of activated methylene species. Under mild reaction conditions (RT to 40 °C), Cu(OTf)2 mediates the selective coupling of functionalized aryl boron species with a variety of stabilized sp(3) -nucleophiles....

Bilayer graphene. Electron-hole asymmetric integer and fractional quantum Hall effect in bilayer graphene.

Science (New York, N.Y.)

Kou A, Feldman BE, Levin AJ, Halperin BI, Watanabe K, Taniguchi T, Yacoby A.
PMID: 24994644
Science. 2014 Jul 04;345(6192):55-7. doi: 10.1126/science.1250270. Epub 2014 May 29.

The nature of fractional quantum Hall (FQH) states is determined by the interplay between the Coulomb interaction and the symmetries of the system. The distinct combination of spin, valley, and orbital degeneracies in bilayer graphene is predicted to produce...

Conductivity tensor of striped quantum hall phases.

Physical review letters

von Oppen F, Halperin BI, Stern A.
PMID: 11018980
Phys Rev Lett. 2000 Mar 27;84(13):2937-40. doi: 10.1103/PhysRevLett.84.2937.

We study the transport properties of pinned striped quantum Hall phases. We show that, under quite general assumptions, the macroscopic conductivity tensor satisfies a semicircle law. In particular, this result is valid for both smectic and nematic stripe phases,...

Strong enhancement of drag and dissipation at the weak- to strong-coupling phase transition in a bilayer system at a total Landau level filling nu = 1.

Physical review letters

Stern A, Halperin BI.
PMID: 11909380
Phys Rev Lett. 2002 Mar 11;88(10):106801. doi: 10.1103/PhysRevLett.88.106801. Epub 2002 Feb 20.

We consider a bilayer electronic system at a total Landau level filling factor nu = 1, and focus on the transition from the regime of weak interlayer coupling to that of the strongly coupled (1,1,1) phase (or "quantum Hall...

Central Nervous System Lyme Disease.

Current infectious disease reports

Halperin JJ.
PMID: 15265459
Curr Infect Dis Rep. 2004 Aug;6(4):298-304. doi: 10.1007/s11908-004-0052-z.

Nervous system infection with Borrelia burgdorferi frequently causes meningitis and rarely causes encephalomyelitis. Altered cognitive function also can occur in the absence of central nervous system infection. Recently developed serodiagnostic tools, such as the C6 assay, and appropriate use...

Spin-charge separation and localization in one dimension.

Science (New York, N.Y.)

Auslaender OM, Steinberg H, Yacoby A, Tserkovnyak Y, Halperin BI, Baldwin KW, Pfeiffer LN, West KW.
PMID: 15802599
Science. 2005 Apr 01;308(5718):88-92. doi: 10.1126/science.1107821.

We report on measurements of quantum many-body modes in ballistic wires and their dependence on Coulomb interactions, obtained by tunneling between two parallel wires in an GaAs/AlGaAs heterostructure while varying electron density. We observed two spin modes and one...

Superfluid-insulator transition in a moving system of interacting bosons.

Physical review letters

Altman E, Polkovnikov A, Demler E, Halperin BI, Lukin MD.
PMID: 16090666
Phys Rev Lett. 2005 Jul 08;95(2):020402. doi: 10.1103/PhysRevLett.95.020402. Epub 2005 Jul 06.

We analyze the stability of superfluid currents in a system of strongly interacting ultracold atoms in an optical lattice. We show that such a system undergoes a dynamic, irreversible phase transition at a critical phase gradient that depends on...

Neurobiological models of attention-deficit/hyperactivity disorder: a brief review of the empirical evidence.

CNS spectrums

Schulz KP, Himelstein J, Halperin JM, Newcorn JH.
PMID: 18268457

Attention-deficit/hyperactivity disorder (ADHD) is a psychiatric disorder characterized by inattention, impulsivity, and overactivity that begins in childhood. While considerable research has focused on the neurobiological substrates of this disorder, the specific nature of the brain dysfunction in ADHD has...
