Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Maximiliano Isi, Sylvia Biscoveanu, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spins are among the key observables for gravitational wave astronomy. Among the spin parameters, their orientations within the orbital plane, $phi_1$, $phi_2$ and $Delta phi=phi_1-phi_2$, are critical for understanding the prevalence […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Tianzhe Zheng, Andrei Faraon, | Summary: Photonic topology optimization is a technique used to find the electric permittivity distribution of a device that optimizes an electromagnetic figure-of-merit. Two common techniques are used: continuous density-based optimizations that optimize a grey-scale permittivity defined over a […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Harald Putterman, Joseph Iverson, Qian Xu, Liang Jiang, Oskar Painter | Summary: Biased-noise qubits are a promising candidate for realizing hardware efficient fault-tolerant quantum computing. One promising biased-noise qubit is the Kerr cat qubit, which has recently been demonstrated experimentally. Despite various unique advantages of Kerr cat […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Harald Putterman, Joseph Iverson, Qian Xu, Liang Jiang, Oskar Painter | Summary: Protected qubits such as the 0-$pi$ qubit, and bosonic qubits including cat qubits and GKP qubits offer advantages for fault-tolerance. Some of these protected qubits (e.g., 0-$pi$ qubit and Kerr cat qubit) are stabilized by […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Dan Hooper, Gordan Krnjaic, , | Summary: The long-standing $4.2 , sigma$ muon $g-2$ anomaly may be the result of a new particle species which could also couple to dark matter and mediate its annihilations in the early universe. In models where both muons and […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Manuel Arca Sedda, Stanislav Babak, Christopher P. L. Berry, Emanuele Berti | Summary: The science objectives of the LISA mission have been defined under the implicit assumption of a 4 yr continuous data stream. Based on the performance of LISA Pathfinder, it is […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Rainer Beck, Susan E. Clark, Annie Hughes, Alejandro S. Borlaff | Summary: Galactic bars are frequent in disk galaxies and they may support the transfer of matter towards the central engine of active nuclei. The barred galaxy NGC 1097 has magnetic forces controlling the […]
Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Jacob H. Davidson, Philip J. T. Woodburn, Aaron D. Marsh, Kyle J. Olson, Adam Olivera | Summary: We characterize the magnetic properties for thulium ion energy levels in the Y$_3$Ga$_5$O$_{12}$ (Tm:YGG) lattice with the goal to improve decoherence and reduce line-width broadening caused by local host spins […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: By computing the low-lying energy excitation spectra with the density matrix renormalization group algorithm we confirm the boundary conformal field theory predictions for the three-state Potts minimal model in 1+1D with boundaries polarized in the direction of the transverse field. […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, Bridget C. Andersen, Kevin Bandura, Mohit Bhardwaj, P. J. Boyle | Summary: The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we report the detection […]
