• Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies ﻿

(2015)
Measurements of two-particle angular correlations between an identified strange hadron (KS0 or Λ/Λ¯) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and full azimuth. ...
• Longitudinal and transverse spin asymmetries for inclusive jet production at mid-rapidity in polarized p+p collisions at √s=200  GeV ﻿

(2012)
We report STAR measurements of the longitudinal double-spin asymmetry ALL, the transverse single-spin asymmetry AN, and the transverse double-spin asymmetries AΣ and ATT for inclusive jet production at mid-rapidity in ...
• Longitudinal double-spin asymmetries for ${\ensuremath{\pi}}^{0}\mathrm{s}$ in the forward direction for 510 GeV polarized $pp$ collisions ﻿

(2018)
The STAR Collaboration reports measurements of the longitudinal double-spin asymmetry, ALL, for neutral pions produced at forward directions in polarized proton-proton collisions, at a center-of-mass energy of 510 GeV. ...
• Longitudinal double-spin asymmetries for dijet production at intermediate pseudorapidity in polarized $pp$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$ ﻿

(2018)
We present the first measurements of the longitudinal double-spin asymmetry ALL for dijets with at least one jet reconstructed within the pseudorapidity range 0.8<η<1.8. The dijets were measured in polarized pp collisions ...

• Low-carrier density and fragile magnetism in a Kondo lattice system ﻿

(2019)
Kondo-based semimetals and semiconductors are of extensive current interest as a viable platform for strongly correlated states in the dilute carrier limit. It is thus important to explore the routes to understand such ...
• Low-temperature conductivity of weakly interacting quantum spin Hall edges in strained-layer InAs/GaInSb ﻿

(2017)
We report low-temperature transport measurements in strainedﾠInAs/Ga0.68In0.32Sbﾠquantum wells, which supports time-reversal symmetry-protected helical edge states. The temperature and bias voltage dependence of the helical ...
• Lowered pH Leads to Fusion Peptide Release and a Highly Dynamic Intermediate of Influenza Hemagglutinin ﻿

(2016)
Hemagglutinin (HA), the membrane-bound fusion protein of the influenza virus, enables the entry of virus into host cells via a structural rearrangement. There is strong evidence that the primary trigger for this rearrangement ...
• Macroscopic Ensembles of Aligned Carbon Nanotubes in Bubble Imprints Studied by Polarized Raman Microscopy ﻿

(2014)
We study the alignment of single-wall carbon nanotubes (SWCNTs) in bubble imprints through polarized Raman microscopy. A hemispherical bubble containing SWCNTs is pressed against a glass substrate, resulting in an imprint ...
• Magnesium Fluctuations Modulate RNA Dynamics in the SAM-I Riboswitch ﻿

(2012)
Experiments demonstrate that Mg2+ is crucial for structure and function of RNA systems, yet the detailed molecular mechanism of Mg2+ action on RNA is not well understood. We investigate the interplay between RNA and Mg2+ ...
• A magnesium-induced triplex pre-organizes the SAM-II riboswitch ﻿

(2017)
Our 13C- and 1H-chemical exchange saturation transfer (CEST) experiments previously revealed a dynamic exchange between partially closed and open conformations of the SAM-II riboswitch in the absence of ligand. Here, ...
• Magnetic and Ising quantum phase transitions in a model for isoelectronically tuned iron pnictides ﻿

(2016)
Considerations of the observed bad-metal behavior in Fe-based superconductors led to an early proposal for quantum criticality induced by isoelectronic P for As doping in iron arsenides, which has since been experimentally ...
