Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, Evan McDonough, , | Summary: We study gravitational particle production of the massive spin-$3/2$ Rarita-Schwinger field, and its close relative, the gravitino, in FRW cosmological spacetimes. For masses lighter than the value of the Hubble expansion rate after inflation, $m_{3/2} […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Hugh Garsden, Lincoln Greenhill, Gianni Bernardi, Anastasia Fialkov, Daniel C. Price | Summary: The Large-aperture Experiment to detect the Dark Age (LEDA) was designed to measure the 21-cm signal from neutral hydrogen at Cosmic Dawn, $z approx $15-30. Using observations made with the $approx $ 200 m […]
Kavli Affiliate: Katja C. Nowack | First 5 Authors: D. Low, G. M. Ferguson, Alexander Jarjour, Brian T. Schaefer, Maja D. Bachmann | Summary: We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least 30 mK. The microscope is […]
Kavli Affiliate: Subo Dong | First 5 Authors: S. J. Brennan, M. Fraser, J. Johansson, A. Pastorello, R. Kotak | Summary: We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current literature by adding higher cadence as well as extended coverage […]
Kavli Affiliate: R. Morris | First 5 Authors: Cuc K. Dinh, Jesus M. Salas, Mark R. Morris, Smadar Naoz, | Summary: A Circumnuclear Disk (CND) of molecular gas occupies the central few parsecs of the Galactic Center. It is likely subject to turbulent disruptions from violent events in its surrounding environment, but the effect of […]
Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Suk Hyun Sung, Noah Schnitzer, Steve Novakov, Ismail El Baggari, Xiangpeng Luo | Summary: Compelling evidence suggests distinct correlated electron behavior may exist only in clean 2D materials such as 1T-TaS2. Unfortunately, experiment and theory suggest that extrinsic disorder in free standing 2D layers disrupts correlation-driven […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Ryuichiro Kitano, Ryutaro Matsudo, Norikazu Yamada, Masahito Yamazaki, | Summary: We propose a subvolume method to study the $theta$ dependence of the free energy density of the four-dimensional SU($N$) Yang-Mills theory on the lattice. As an attempt, the method is first applied to SU(2) Yang-Mills theory at […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shun-ichi Horigome, Taisuke Katayose, Shigeki Matsumoto, Ipsita Saha, | Summary: The leptophilic weakly interacting massive particle (WIMP) is realized in a minimal renormalizable model scenario where scalar mediators with lepton number establish the WIMP interaction with the standard model (SM) leptons. We perform a comprehensive analysis for […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Mit H. Naik, Jingxu Xie, Xinyu Li | Summary: Transition metal dichalcogenide (TMD) moir’e heterostructures provide an ideal platform to explore the extended Hubbard model1 where long-range Coulomb interactions play a critical role in determining strongly correlated electron states. This has led […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Richard Luhtaru, Paul L. Schechter, Kaylee M. de Soto, , | Summary: Among known strongly lensed quasar systems, ~25% have gravitational potentials sufficiently flat (and sources sufficiently well aligned) to produce four images rather than two. The projected flattening of the lensing galaxy and tides from […]
