Kavli Affiliate: C. L. Kuo | First 5 Authors: J. A. Sobrin, A. J. Anderson, A. N. Bender, B. A. Benson, D. Dutcher | Summary: SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements of the temperature and polarization anisotropies […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Vidya Muthukumar, Christos Thrampoulidis, , | Summary: The literature on "benign overfitting" in overparameterized models has been mostly restricted to regression or binary classification; however, modern machine learning operates in the multiclass setting. Motivated by this discrepancy, we study benign overfitting in multiclass linear classification. […]
Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Mikel Gómez Ruiz, Kevin Lee, Henryk Turski, Shyam Bharadwaj | Summary: This report classifies emission inhomogeneities that manifest in InGaN quantum well blue light-emitting diodes grown by plasma-assisted molecular beam epitaxy on free-standing GaN substrates. By a combination of spatially resolved electroluminescence and cathodoluminescence […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Emma C. Regan, Danqing Wang, Wenyu Zhao | Summary: The Wigner crystal state, first predicted by Eugene Wigner in 1934, has fascinated condensed matter physicists for nearly 90 years2-14. Studies of two-dimensional (2D) electron gases first revealed signatures of the Wigner crystal […]
Kavli Affiliate: Ronald Hanson | First 5 Authors: Weiqi Ji, Xingyu Su, Bin Pang, Sean Joseph Cassady, Alison M. Ferris | Summary: Combustion kinetic modeling is an integral part of combustion simulation, and extensive studies have been devoted to developing both high fidelity and computationally affordable models. Despite these efforts, modeling combustion kinetics is still […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Sai Sharan Injeti, Paolo Celli, Kaushik Bhattacharya, Chiara Daraio, | Summary: Acoustic transparency is the capability of a medium to transmit mechanical waves to adjacent media, without scattering. This characteristic can be achieved by carefully engineering the acoustic impedance of the medium — a combination of wave […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Hitoshi Murayama, Ofri Telem, | Summary: We demonstrate that $SO(N_{c})$ gauge theories with matter fields in the vector representation confine due to monopole condensation and break the $SU(N_{F})$ chiral symmetry to $SO(N_{F})$ via the quark bilinear. Our results are obtained by perturbing the […]
Kavli Affiliate: Ariel Amir | First 5 Authors: Ahmad Zareei, Deng Pan, Ariel Amir, , | Summary: We study the dynamics of flow-networks in porous media using a pore-network model. First, we consider a class of erosion dynamics assuming a constitutive law depending on flow rate, local velocities, or shear stress at the walls. We […]
Kavli Affiliate: Tom Abel | First 5 Authors: Santi Roca-Fàbrega, Ji-hoon Kim, Loic Hausammann, Kentaro Nagamine, Johnny W. Powell | Summary: We present a suite of high-resolution cosmological zoom-in simulations to $z=4$ of a $10^{12},{rm M}_{odot}$ halo at $z=0$, obtained using seven contemporary astrophysical simulation codes widely used in the numerical galaxy formation community. Physics […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Enrico Barausse, Emanuele Berti, Vitor Cardoso, Scott A. Hughes, Gaurav Khanna | Summary: A powerful technique to calculate gravitational radiation from binary systems involves a perturbative expansion: if the masses of the two bodies are very different, the "small" body is treated as a point particle […]
