Models describing dark matter as a novel particle often predict that its annihilation or decay into Standard Model particles could produce a detectable neutrino flux in regions of high dark matter density, such as the Galactic Center. In this work, we search for these neutrinos using ∼9 years of IceCube-DeepCore data with an event selection optimized for energies between 15 to 200 GeV. [...]

The all-sky very-high-energy (10$^{4}$ − 10$^{6}$ GeV) atmospheric muon flux measured by IceCube shows a spectral hardening at the highest energies, indicating the presence of a prompt component. IceCube has also measured the atmospheric muon neutrino flux at high energy. [...]

Polymer crystallization under nanoscale confinementis governed by finite-size and interfacial effects, yet its behavior atlength scales approaching the lamellar thickness remains poorlyunderstood. Here, we investigate the crystallization of poly(ethyleneoxide) (PEO) with varying molecular weights confined within siliconnanopores (d ∼ 7–8 nm). [...]

Solid−liquid contact electrification is widely studied using diverseexperimental geometries that are often implicitly assumed to probe equivalentinterfacial processes. Here, we directly test this assumption by comparingimmersion−emersion, droplet-based contact, and pressure-driven intrusion−extrusion electrification using the same hydrophobic nanoporous silicon monolithand isotopically substituted liquids (H2O and D2O). [...]

We compute thermal holographic correlators by combining their analytic structure with the Kubo-Martin-Schwinger (KMS) condition and multi-stress tensor OPE coefficients determined from the dual AdS description. We focus on two-point functions of identical scalar operators with integer conformal dimensions at zero spatial separation. [...]

We propose new universal formulae for thermal two-point functions of scalar operators based on their analytic structure, constructed to manifestly satisfy all the bootstrap conditions. We derive a dispersion relation in the complexified time plane, which fixes the correlator up to an additive constant and theory-dependent dynamical information. [...]

Effective field theories (EFTs) provide an excellent framework for the search of heavy physics beyond the Standard Model, using the so-called bottom-up and top-down approaches. However, the vastness of possible UV scenarios makes the complete connection between the two approaches a difficult challenge at the loop-level. [...]

The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks and cascade events from neutrino interactions. We present two analyses sensitive to neutrino events in the energy range \SI1{TeV} to \SI{10}{PeV}, using more than 10 years of IceCube data. [...]

Organic compounds are key components of atmospheric aerosols and often act as surfactants in cloud droplets and fine particles. While the interfacial behavior of individual species in binary systems is fairly well-understood, less is known about interactions between multiple surface-active organics. [...]
