• #### Gapless topological Fulde-Ferrell superfluidity induced by an in-plane Zeeman field ﻿

(2014)
Topological superfluids are recently discovered quantum matter that hosts topologically protected gapless edge states known as Majorana fermions—exotic quantum particles that act as their own antiparticles and obey non-Abelian ...
• #### Gas density drops inside dust cavities of transitional disks around young stars observed with ALMA ﻿

(2015)
Context. Transitional disks with large dust cavities are important laboratories in which to study planet formation and disk evolution. Cold gas may still be present inside these cavities, but quantying this gas is challenging. ...
• #### Generalized Manning Condensation Model Captures the RNA Ion Atmosphere ﻿

(2015)
RNA is highly sensitive to the ionic environment and typically requires Mg2+ to form compact structures. There is a need for models capable of describing the ion atmosphere surrounding RNA with quantitative accuracy. We ...
• #### Genomics-aided structure prediction ﻿

(2012)
We introduce a theoretical framework that exploits the everincreasing genomic sequence information for protein structure prediction. Structure-based models are modified to incorporate constraints by a large number of ...
• #### Geometric representation of spin correlations and applications to ultracold systems ﻿

(2018)
We provide a one-to-one map between the spin correlations and certain three-dimensional shapes, analogous to the map between single spins and Bloch vectors, and demonstrate its utility. Much as one can reason geometrically ...
• #### Geometrical Frustration in Interleukin-33 Decouples the Dynamics of the Functional Element from the Folding Transition State Ensemble ﻿

(2015)
Interleukin-33 (IL-33) is currently the focus of multiple investigations into targeting pernicious inflammatory disorders. This mediator of inflammation plays a prevalent role in chronic disorders such as asthma, rheumatoid ...
• #### Giant Terahertz-Wave Absorption by Monolayer Graphene in a Total Internal Reflection Geometry ﻿

(2017)
We experimentally demonstrated significant enhancement of terahertz-wave absorption in monolayer graphene by simply sandwiching monolayer graphene between two dielectric media in a total internal reflection geometry. In ...
• #### Giant tunable Faraday effect in a semiconductor magneto-plasma for broadband terahertz polarization optics ﻿

(2012)
We report on a giant Faraday effect in an electron plasma in n- InSb probed via polarization-resolved terahertz (THz) time-domain spectroscopy. Polarization rotation angles and ellipticities reach as large as π/2 and 1, ...
• #### Glide reflection symmetry, Brillouin zone folding, and superconducting pairing for the P4/nmm space group ﻿

(2015)
Motivated by the studies of the superconducting pairing states in the iron-based superconductors, we analyze the effects of Brillouin zone folding procedure from a space-group symmetry perspective for a general class of ...
• #### Global MHD modeling of resonant ULF waves: Simulations with and without a plasmasphere ﻿

(2016)
We investigate the plasmaspheric influence on the resonant mode coupling of magnetospheric ultralow frequency (ULF) waves using the Lyon-Fedder-Mobarry (LFM) global magnetohydrodynamic (MHD) model. We present results from ...
• #### Global polarization of $\mathrm{\ensuremath{\Lambda}}$ hyperons in Au + Au collisions at $\sqrt{{s}_{NN}}=200$ GeV ﻿

(2018)
Global polarization of Λ hyperons has been measured to be of the order of a few tenths of a percentage in Au+Au collisions at √sNN = 200 GeV, with no significant difference between Λ and ¯¯¯Λ. These new results reveal the ...
• #### Gold coated iron phosphide core–shell structures ﻿

(2017)
Core–shell particles Fe2P@Au have been prepared beginning with Fe2P nanorods, nanocrosses and nanobundles prepared from the solvothermal decomposition of H2Fe3(CO)9(μ3-PtBu). Iron phosphide structures can be produced from ...
• #### Gradual enhancement of stripe-type antiferromagnetism in the spin-ladder material BaFe2S3 under pressure ﻿

(2018)
We report pressure-dependent neutron diffraction and muon spin relaxation/rotation measurements combined with first-principles calculations to investigate the structural, magnetic, and electronic properties of BaFe2S3 under ...
• #### Gravitational perturbations from oscillons and transients after inflation ﻿

(2019)
We study the scalar and tensor perturbations generated by the fragmentation of the inflaton condensate into oscillons or transients after inflation, using nonlinear classical lattice simulations. Without including the ...
• #### GRB110721A: An Extreme Peak Energy and Signatures of the Photosphere ﻿

(2012)
GRB110721A was observed by the Fermi Gamma-ray Space Telescope using its two instruments, the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). The burst consisted of one major emission episode which lasted ...
• #### Ground-based magnetometer determination of in situ Pc4–5 ULF electric field wave spectra as a function of solar wind speed ﻿

(2012)
We present a statistical characterization of ground-based ultra-low-frequency ( 1–15 mHz) magnetic wave power spectral densities (PSDs) as a function of latitude (corresponding to dipole L-shells from L 2.5–8), local ...
• #### Growth and Collapse of a Bose-Einstein Condensate with Attractive Interactions ﻿

(1998)
We consider the dynamics of a quantum degenerate trapped gas of 7Li atoms. Because the atoms have a negative s-wave scattering length, a Bose condensate of 7Li becomes mechanically unstable when the number of condensate ...
• #### The Harang reversal and the interchange stability of the magnetotail ﻿

(2016)
The present study addresses steady convection in the plasma sheet in terms of the interchange stability with special attention to the Harang reversal. The closure of the tail current with a field-aligned current (FAC) ...
• #### Hard X-ray quiescent emission in magnetars via resonant Compton upscattering ﻿

(2017)
Non-thermal quiescent X-ray emission extending between 10 keV and around 150 keV has been seen in about 10 magnetars by RXTE, INTEGRAL, Suzaku, NuSTAR and Fermi-GBM. For inner magnetospheric models of such hard X-ray ...
