Rapid Autotuning of a SiGe Quantum Dot into the Single-Electron Regime with Machine Learning and RF-Reflectometry FPGA-Based Measurements
Spin qubits need to operate within a very precise voltage space around charge state transitions to achieve high-fidelity gates. However, the stability diagrams that allow the identification of the desired charge states are long to acquire. Moreover, the voltage space to search for the desired charge state increases quickly with the number of qubits. Therefore, faster stability diagram acquisitions are needed to scale up a spin qubit quantum processor. Currently, most methods focus on more effic…

First Full Dalitz Plot Measurement in Neutron $β$-Decay using the Nab Spectrometer and Implications for New Physics
Precision measurements of observables in neutron $β$-decay are used to test the Standard Model description of the weak interaction and search for evidence of new physics. The Nab experiment at the Fundamental Neutron Physics Beamline at the Spallation Neutron Source was constructed to measure correlations in neutron decay by utilizing an asymmetric spectrometer and novel detection system to accurately reconstruct the proton momentum and electron energy for each $β$-decay. This work describes …

Excitation of the non-resonant streaming instability around sources of Ultra-High Energy Cosmic Rays
The interpretation of the ultra-high-energy cosmic ray spectrum (UHECRs) and composition suggests a suppression of the flux below $\sim$1 EeV, as observed by the Pierre Auger Observatory and Telescope Array. A natural explanation for this phenomenon involves magnetic confinement effects. We investigate the possibility that UHECRs self-generate the magnetic turbulence necessary for such confinement via current-driven plasma instabilities. Specifically, we show that the electric current produced …

Based on the current congressional map, Inside Elections rates 64 House seats nationwide as being at least somewhat competitive, with a dozen considered toss-ups.
The Cook Political Report,another gold-plated handicapper, rates 72 seats competitive or having the potential to be so, with 18 toss-ups.
Both agree that two of those coin-flip races are in California, where Democrats Adam Gray and Derek Tran are fighting to hang onto seats they narrowly won in, respectively, the Central…

Barabak: Here's why the redistricting fight is raging. And why it may be moot
The partisan passions suggest control of the House will be decided next year by just a few seats, one way or the other. But that's typically not the case.

Low Temperature MOCVD Synthesis of high-mobility 2D InSe
Two-dimensional (2D) indium selenide (InSe) is a layered semiconductor with high electron mobility and a tunable band gap ranging from 1.25 eV in the bulk to 2.8 eV in the monolayer limit. These properties make these materials strong candidates for future logic and optoelectronic devices. However, growing phase-pure InSe remains challenging due to the complex indium-selenium (In-Se) phase diagram. This complexity and the sensitivity of chemical precursors to growth conditions make it difficult …

Characterizing the neutron component of extensive air showers with the Surface-Scintillator Detectors of AugerPrime
Neutrons are the only neutral hadrons that remain stable over the timescale of an air-shower development. Their energy is lost only through hadronic interactions and quasi-elastic scattering, which results in their high abundance at the ground. The signals from the electromagnetic and muonic components in scintillation detectors typically span only a few microseconds. In contrast, the neutrons can cause delayed pulses in scintillation detectors up to and beyond several milliseconds after the pa…

Unveiling two-dimensional electron systems on ultra-wide bandgap semiconductor $\mathrmβ$-Ga$_2$O$_3$
Ultra-wide bandgap (UWBG) semiconductors promise to revolutionize power electronics, yet a fundamental understanding of their interfacial electronic structure has been hindered by the absence of direct experimental observation. Here, we report the first momentum-resolved observation of two-dimensional electron systems on a UWBG material, enabled by angle resolved photoemission spectroscopy (ARPES) on high-purity $β$-Ga$_2$O$_3$ single crystals. Alkaline-metal-induced electron doping forms an i…

Characterization of downward Terrestrial Gamma-ray Flashes detected at the Pierre Auger Observatory
Downward Terrestrial Gamma-ray Flashes (TGFs) are sub-millisecond bursts of MeV gamma rays produced in thunderclouds. According to the Relativistic Runaway Electron Avalanche model, gamma rays are produced, via bremsstrahlung, from electron cascades activated by a relativistic "seed" electron. It is not clear what mechanism is responsible for the acceleration of electrons to relativistic energies in electric discharges. To better understand the acceleration sites and the TGF production mechanis…
