Kavli Affiliate: Alireza Marandi | First 5 Authors: Arkadev Roy, Luis Ledezma, Luis Costa, Robert Gray, Ryoto Sekine | Summary: Optical frequency comb is an enabling technology for a multitude of applications from metrology to ranging and communications. The tremendous progress in sources of optical frequency combs has mostly been centered around the near-infrared spectral […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yanan Wang, Ranieri D. Baldi, Santiago del Palacio, Muryel Guolo, Xiaolong Yang | Summary: AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and the infrared […]
Kavli Affiliate: Ulrich Sperhake | Summary:We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer it et al (2019 Phys. Rev. D 99 044046; 2022 Class. Quantum Grav. 39 074001) to arbitrary mass ratios. We demonstrate how these improved initial data avoid substantial spurious artifacts in the collision […]
Kavli Affiliate: Taizan Watari | Summary:One can assign to four-dimensional N=2 supersymmetric Heterotic string vacua a set of classification invariants including a lattice $Λ_S$ and vector-valued modular forms. Some of the classification invariants are constrained by the condition that the Coulomb branch monodromy matrices should be integer-valued. We computed numerically the period polynomials of meromorphic […]
Kavli Affiliate: Alessandra Lanzara | Summary:$α$-RuCl$_3$ is considered to be the top candidate material for the experimental realization of the celebrated Kitaev model. It is however known that additional interactions beyond the Kitaev model trigger in $α$-RuCl$_3$, a long-range zigzag antiferromagnetic ground state. In this work, we investigate a nanoflake of $α$-RuCl$_3$ through guarded high […]
Kavli Affiliate: Timothy A. Ryan | Authors: Mukesh Kumar, Justin Knapp, Kallol Gupta and Timothy A Ryan | Summary: Recent advances have expanded the role of lipid droplets (LDs) beyond passive lipid storage, implicating their involvement in various metabolic processes across mammalian tissues. Neuronal LDs, long debated in existence, have been identified in several neural […]
Kavli Affiliate: Gary Steele | Summary:Harmonic oscillators belong to the most fundamental concepts in physics and are central to many current research fields such as circuit QED, cavity optomechanics and photon-pressure systems. Here, we engineer a microwave mode in a superconducting LC circuit that mimics the dynamics of a negative mass oscillator, and couple it […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao, Risa H. Wechsler, Marla Geha | Summary: We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method. Our selection consists of a […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Jiawen Fan, Hanjue Zhu, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Lyman limit systems (LLSs) are dense hydrogen clouds with high enough HI column densities to absorb Lyman continuum photons emitted from distant quasars. Their high column densities imply an origin in dense environments; however, the […]
