Search for supersymmetry in proton-proton collisions at s√= 13 TeV in events with high-momentum Z bosons and missing transverse momentum
(2020)A search for new physics in events with two highly Lorentz-boosted Z bosons and large missing transverse momentum is presented. The analyzed proton-proton collision data, corresponding to an integrated luminosity of 137 ... -
Studies of Charm Quark Diffusion inside Jets Using Pb-Pb and pp Collisions at √sNN=5.02 TeV
(2020)The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with pjetT>60 GeV/c and D0 mesons with pDT>4 GeV/c in lead-lead (Pb-Pb) ... -
Emission-line Data Cubes of the HH 32 Stellar Jet
(2020)We analyze data cubes of over 60 emission lines in the HH 32 stellar jet acquired with the Keck Cosmic Web Imager (KCWI). The data cover the less explored blue portion of the spectrum between 3586 and 6351 Å and have both ... -

Tuning magnetic confinement of spin-triplet superconductivity
(2020)Electrical magnetoresistance and tunnel diode oscillator measurements were performed under external magnetic fields up to 41 T applied along the crystallographic b axis (hard axis) of UTe2 as a function of temperature and ... -
Correlating the antisymmetrized geminal power wave function
(2020)Strong pairing correlations are responsible for superconductivity and off-diagonal long-range order in the two-particle density matrix. The antisymmetrized geminal power wave function was championed many years ago as the ... -
Theoretical investigation of superconductivity in trilayer square-planar nickelates
(2020)The discovery of superconductivity in Sr-doped NdNiO2 is a crucial breakthrough in the long pursuit for nickel oxide materials with electronic and magnetic properties similar to those of the cuprates. NdNiO2 is the ... -
Investigation of the linear and mode-coupled flow harmonics in Au+Au collisions at sNN = 200 GeV
(2020)Flow harmonics (vn) of the Fourier expansion for the azimuthal distributions of hadrons are commonly employed to quantify the azimuthal anisotropy of particle production relative to the collision symmetry planes. While ... -
Electronic and Magnetic Anisotropies in FeSe Family of Iron-Based Superconductors
(2020)Most parent compounds of iron-based superconductors (FeSCs) exhibit a tetragonal-to-orthorhombic lattice distortion below Ts associated with an electronic nematic phase that breaks the four-fold (C4) rotational symmetry ... -
Giant photothermoelectric effect in silicon nanoribbon photodetectors
(2020)The photothermoelectric (PTE) effect enables efficient harvesting of the energy of photogenerated hot carriers and is a promising choice for high-efficiency photoelectric energy conversion and photodetection. Recently, the ... -
Measurement of CKM matrix elements in single top quark t-channel production in proton-proton collisions at s=13 TeV
(2020)The first direct, model-independent measurement is presented of the modulus of the Cabibbo–Kobayashi–Maskawa (CKM) matrix elements |η|Vtb, |η|Vtd, and |η|Vts, in final states enriched in single top quark t-channel events. ... -
Measurement of the Y(1S) pair production cross section and search for resonances decaying to Y(1S)μ+μ− in proton-proton collisions at s=13TeV
(2020)The fiducial cross section for Y(1S) pair production in proton-proton collisions at a center-of-mass energy of 13 TeV in the region where both Y(1S) mesons have an absolute rapidity below 2.0 is measured to be 79±11(stat ... -
Polarized evanescent waves reveal trochoidal dichroism
(2020)Matter’s sensitivity to light polarization is characterized by linear and circular polarization effects, corresponding to the system’s anisotropy and handedness, respectively. Recent investigations into the near-field ... -
Heavy fermion quantum criticality at dilute carrier limit in CeNi2−δ(As1−xPx)2
(2019)We study the quantum phase transitions in the nickel pnctides, CeNi2−δ(As1−xPx)2 (δ ≈ 0.07–0.22) polycrystalline samples. This series displays the distinct heavy fermion behavior in the rarely studied parameter regime of ... -
Tunneling noise and defects in exfoliated hexagonal boron nitride
(2019)Hexagonal boron nitride (hBN) has become a mainstay as an insulating barrier in stackable nanoelectronics because of its large bandgap and chemical stability. At mono- and bilayer thicknesses, hBN can function as a tunnel ... -
Phase of confined electroweak force in the early Universe
(2019)We consider a modified cosmological history in which the presence of beyond-the-Standard-Model physics causes the weak gauge sector, SU(2)L, to confine before it is Higgsed. Under the assumption of chiral symmetry breaking, ... -
High‐Frequency Wave Generation in Magnetotail Reconnection: Linear Dispersion Analysis
(2019)Plasma and wave measurements from the NASA Magnetospheric Multiscale mission are presented for magnetotail reconnection events on 3 July and 11 July 2017. Linear dispersion analyses were performed using distribution functions ... -
Science and applications of wafer-scale crystalline carbon nanotube films prepared through controlled vacuum filtration
(2019)Carbon nanotubes (CNTs) make an ideal one-dimensional (1D) material platform for the exploration of novel physical phenomena under extremely strong quantum confinement. The 1D character of electrons, phonons and excitons ...
