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 […]
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 […]
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 […]
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 […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: The scalar field theory of cosmological inflation constitutes nowadays one of the preferred scenarios for the physics of the early universe. In this paper we aim at studying the inflationary universe making use of a numerical […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Jack Sayers, Mauro Sereno, Stefano Ettori, Elena Rasia, Weiguang Cui | Summary: We report the non-thermal pressure fraction (Pnt/Ptot) obtained from a three-dimensional triaxial analysis of 16 galaxy clusters in the CLASH sample using gravitational lensing (GL) data primarily from Subaru and HST, X-ray spectroscopic imaging from […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Benjamin M. Tofflemire, Aaron C. Rizzuto, Elisabeth R. Newton, Adam L. Kraus, Andrew W. Mann | Summary: The detection and characterization of young planetary systems offers a direct path to study the processes that shape planet evolution. We report on the discovery of a sub-Neptune-size planet orbiting […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Elisabeth R. Newton, Andrew W. Mann, Adam L. Kraus, John H. Livingston, Andrew Vanderburg | Summary: Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC 257605131, Gaia DR2 4844691297067063424). […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Raisa-Ioana Biega, Marina R. Filip, Linn Leppert, Jeffrey B. Neaton, | Summary: Halide double perovskites with alternating silver and pnictogen cations are an emerging family of photoabsorber materials with robust stability and band gaps in the visible range. However, the nature of optical excitations in these […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Oscar Macias, Harm van Leijen, Deheng Song, Shin’ichiro Ando, Shunsaku Horiuchi | Summary: The leading explanation of the $textit{Fermi}$ Galactic center $gamma$-ray excess is the extended emission from a unresolved population of millisecond pulsars (MSPs) in the Galactic bulge. Such a population would, along with the prompt […]
