Possible X-ray Quasi-Periodic Eruptions in a Tidal Disruption Event Candidate

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Megan Masterson, Margherita Giustini, Giovanni Miniutti | Summary: X-ray Quasi-Periodic Eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high amplitude soft X-ray flares that recur on timescales of hours, but what causes […]

A Logarithmic Bayesian Approach to Quantum Error Detection

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, K. Birgitta Whaley, , , | Summary: We consider the problem of continuous quantum error correction from a Bayesian perspective, proposing a pair of digital filters using logarithmic probabilities that are able to achieve near-optimal performance on a three-qubit bit-flip code while still being […]

Lattice simulations of Abelian gauge fields coupled to axions during Inflation

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We use a lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction. These kinds of models have already been studied with a lattice […]

Lattice Simulations of Abelian Gauge Fields coupled to Axion during Inflation

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We use a non-linear lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction. This kind of models have already been studied with a […]

Rapid growth of seed black holes during early bulge formation

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Riouhei Nakatani, Daisuke Toyouchi, Takashi Hosokawa, Rolf Kuiper | Summary: We study the early growth of massive seed black holes (BHs) via accretion in protogalactic nuclei where the stellar bulge component is assembled, performing axisymmetric two-dimensional radiation hydrodynamical simulations. We find that when a seed […]

Machine Learning for Continuous Quantum Error Correction on Superconducting Qubits

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, Haoran Liao, Song Zhang, Sahil Patel, William P. Livingston | Summary: We propose a machine learning algorithm for continuous quantum error correction that is based on the use of a recurrent neural network to identity bit-flip errors from continuous noisy syndrome measurements. The algorithm […]
