Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Domenico Orlando, , , | Summary: We consider large-R-charge Coulomb branch correlation functions in $mathcal{N} = 2$ superconformal QCD in D=4 dimensions, with gauge group $SU(2)$ and $N_f = 4$ hypermultiplets in the fundamental representation. Using information from supersymmetric recursion relations, S-duality, and matching of […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Pragati Pradhan, David P. Huenemoerder, Richard Ignace, A. M. T Pollock, Joy S. Nichols | Summary: WR 25 is a colliding-wind binary star system comprised of a very massive O2.5If*/WN6 primary and an O-star secondary in a 208-day period eccentric orbit. These hot stars have strong, […]
Kavli Affiliate: Lara A. Estroff | Summary:A pearl’s distinguished beauty and toughness are attributable to the periodic stacking of aragonite tablets known as nacre. Nacre has naturally occurring mesoscale periodicity that remarkably arises in the absence of discrete translational symmetry. Gleaning the inspiring biomineral design of a pearl requires quantifying its structural coherence and understanding […]
Kavli Affiliate: Timon Idema | Summary:Order can spontaneously emerge from seemingly noisy interactions between biological agents, like a flock of birds changing their direction of flight in unison, without a leader or an external cue. We are interested in the generic conditions that lead to such emergent phenomena. To find these conditions, we use the […]
Kavli Affiliate: Daniel Ralph | First 5 Authors: Saba Karimeddiny, Saba Karimeddiny, , , | Summary: When spin-orbit torques are measured using spin-torque ferromagnetic resonance (ST-FMR), two alternative ways of analyzing the results to extract the torque efficiencies — lineshape analysis and analysis of the change in linewidth versus DC current — often give inconsistent […]

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Brian T. Schaefer, Katja C. Nowack, , , | Summary: The valleys in hexagonal two-dimensional systems with broken inversion symmetry carry an intrinsic orbital magnetic moment. Despite this, such systems possess zero net magnetization unless additional symmetries are broken, since the contributions from both valleys cancel. […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Congyao Zhang, Irina Zhuravleva, Andrey Kravtsov, Eugene Churazov, | Summary: A self-similar spherical collapse model predicts a dark matter (DM) splashback and accretion shock in the outskirts of galaxy clusters while misses a key ingredient of structure formation – processes associated with mergers. To fill this gap, […]
Kavli Affiliate: Patricia Burchat | Summary:In Stage-IV imaging surveys, a significant amount of the cosmologically useful information is due to sources whose images overlap with those of other sources on the sky. The cosmic shear signal is primarily encoded in the estimated shapes of observed galaxies and thus directly impacted by overlaps. We introduce a […]
