Leptophilic fermion WIMP ~ Role of future lepton colliders

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 […]

Imaging local discharge cascades for correlated electrons in WS2/WSe2 moiré superlattices

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 […]

What Makes Quadruply Lensed Quasars Quadruple?

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 […]

Vibrational relaxation dynamics in layered perovskite quantum wells

Kavli Affiliate: Peidong Yang | First 5 Authors: Li Na Quan, Yoonjae Park, Peijun Guo, Mengyu Gao, Jianbo Jin | Summary: Organic-inorganic layered perovskites are two-dimensional quantum wells with layers of lead-halide octahedra stacked between organic ligand barriers. The combination of their dielectric confinement and ionic sublattice results in excitonic excitations with substantial binding energies […]

Constraints on Effective Field Theory Couplings Using 311.2 days of LUX Data

Kavli Affiliate: C. M. Ignarra | First 5 Authors: D. S. Akerib, S. Alsum, H. M. Araújo, X. Bai, J. Balajthy | Summary: We report here the results of an Effective Field Theory (EFT) WIMP search analysis using LUX data. We build upon previous LUX analyses by extending the search window to include nuclear recoil […]

Search for non-Newtonian interactions at micrometer scale with a levitated test mass

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Alexander Fieguth, Akio Kawasaki, Nadav Priel, Denzal Martin | Summary: We report on a search for non-Newtonian forces that couple to mass, with a characteristic scale of ${sim}10~mu$m, using an optically levitated microsphere as a precision force sensor. A silica microsphere trapped in an […]

Precise transit and radial-velocity characterization of a resonant pair: a warm Jupiter TOI-216c and eccentric warm Neptune TOI-216b

Kavli Affiliate: Alan M. Levine | First 5 Authors: Rebekah I. Dawson, Chelsea X. Huang, Rafael Brahm, Karen A. Collins, Melissa J. Hobson | Summary: TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS Mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit […]
