Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Antonio L. R. Manesco, Ian Matthias Flór, Chun-Xiao Liu, Anton R. Akhmerov, | Summary: We simulate a hybrid superconductor-graphene device in the quantum Hall regime to identify the origin of downstream resistance oscillations in a recent experiment [Zhao et. al. Nature Physics 16, (2020)]. In addition […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yu Qiu, Brian R. McNamara, Tamara Bogdanovic, Kohei Inayoshi, Luis C. Ho | Summary: Outflows driven by active galactic nuclei (AGN) are an important channel for accreting supermassive black holes (SMBHs) to interact with their host galaxies and clusters. Properties of the outflows are however poorly constrained […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We use covariant phase space methods to study the metric and tetrad formulations of General Relativity in a manifold with boundary and compare the results obtained in both approaches. Proving their equivalence […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Ai Yamakage, Mamoru Matsuo, , | Summary: We present a theoretical investigation of anisotropic superconducting spin transport at a magnetic interface between a p-wave superconductor and a ferromagnetic insulator. Our formulation describes the ferromagnetic resonance modulations due to spin current generation depending on spin-triplet Cooper […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Domenico Orlando, , , | Summary: We consider large-R-charge Coulomb branch correlation functions in $mathcal{N} = 2$ superconformal QCD in D=4 dimensions, with gauge group $SU(2)$ and $N_f = 4$ hypermultiplets in the fundamental representation. Using information from supersymmetric recursion relations, S-duality, and matching of […]
Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Guglielmo Mastroserio, Erin Kara, Javier García, Adam Ingram | Summary: We analyze 5 epochs of NICER data of the black hole X-ray binary MAXI J1820+070 during the bright hard-to-soft state transition in its 2018 outburst with both reflection spectroscopy and Fourier-resolved timing analysis. We confirm […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Pragati Pradhan, David P. Huenemoerder, Richard Ignace, A. M. T Pollock, Joy S. Nichols | Summary: WR 25 is a colliding-wind binary star system comprised of a very massive O2.5If*/WN6 primary and an O-star secondary in a 208-day period eccentric orbit. These hot stars have strong, […]
Kavli Affiliate: Lara A. Estroff | First 5 Authors: Jiseok Gim, Alden Koch, Laura M. Otter, Benjamin H. Savitzky, Sveinung Erland | Summary: A pearl’s distinguished beauty and toughness are attributable to the periodic stacking of aragonite tablets known as nacre. Nacre has naturally occurring mesoscale periodicity that remarkably arises in the absence of discrete […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Agnes Valenti, Eliska Greplova, Netanel H. Lindner, Sebastian D. Huber, | Summary: Variational methods have proven to be excellent tools to approximate ground states of complex many body Hamiltonians. Generic tools like neural networks are extremely powerful, but their parameters are not necessarily physically motivated. Thus, an […]
Kavli Affiliate: Timon Idema | First 5 Authors: Carsten T. van de Kamp, George Dadunashvili, Johan L. A. Dubbeldam, Timon Idema, | Summary: Order can spontaneously emerge from seemingly noisy interactions between biological agents, like a flock of birds changing their direction of flight in unison, without a leader or an external cue. We are […]
