Extragalactic magnetism with SOFIA (Legacy Program) — II: A magnetically-driven flow in the starburst ring of NGC 1097

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 […]

Measurement of the Thulium Ion Spin Hamiltonian Within a Yttrium Gallium Garnet Host Crystal

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 […]

Critical properties of quantum three- and four-state Potts models with boundaries polarized along the transverse field

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. […]

Sub-second periodicity in a fast radio burst

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 […]

Mid-Infrared Cross-Comb Spectroscopy

Kavli Affiliate: Alireza Marandi | First 5 Authors: Mingchen Liu, Robert M. Gray, Arkadev Roy, Charles R. Markus, Alireza Marandi | Summary: Dual-comb spectroscopy has been proven a powerful tool in molecular characterization, which remains challenging to implement in the mid-infrared (MIR) region due to difficulties in the realization of two mutually locked comb sources […]

XMM-Newton Observes the Intrabinary Shock of PSR J1959+2048

Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Hongjun An, , | Summary: In a multi-orbit (100 ks) $mathrm{it XMM-Newton}$ exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shock (IBS) emission. The IBS light curve peak appears asymmetric, which […]

An Information-state based Approach to the Optimal Output Feedback Control of Nonlinear Systems

Kavli Affiliate: Ran Wang | First 5 Authors: , , , , | Summary: This paper develops a data-based approach to the closed-loop output feedback control of nonlinear dynamical systems with a partial nonlinear observation model. We propose an information state based approach to rigorously transform the partially observed problem into a fully observed problem […]

Long-Range Superconducting Proximity Effect in Nickel Nanowires

Kavli Affiliate: Ke Wang | First 5 Authors: Jue Jiang, Weiwei Zhao, Fei Wang, Renzhong Du, Ludi Miao | Summary: When a ferromagnet is placed in contact with a superconductor, owing to incompatible spin order, the Cooper pairs from the superconductor cannot survive more than one or two nanometers inside the ferromagnet. This is confirmed […]

Warming up cold inflation

Kavli Affiliate: Peter W. Graham | First 5 Authors: William DeRocco, Peter W. Graham, Saarik Kalia, , | Summary: The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically couple to gauge sectors. As the axion […]
