Quantum Information Theory of the Gravitational Anomaly

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Domenico Orlando, Masataka Watanabe, , | Summary: We show that the standard notion of entanglement is not defined for gravitationally anomalous two-dimensional theories because they do not admit a local tensor factorization of the Hilbert space into local Hilbert spaces. Qualitatively, the modular flow cannot […]

Search for Dark Photon Dark Matter: Dark E-Field Radio Pilot Experiment

Kavli Affiliate: Peter Graham | First 5 Authors: Benjamin Godfrey, J. Anthony Tyson, Seth Hillbrand, Jon Balajthy, Daniel Polin | Summary: We are building an experiment to search for dark matter in the form of dark photons in the nano- to milli-eV mass range. This experiment is the electromagnetic dual of magnetic detector dark radio […]

TOI-1259Ab — a gas giant planet with 2.7% deep transits and a bound white dwarf companion

Kavli Affiliate: George Ricker | First 5 Authors: David V. Martin, Kareem El-Badry, Vedad Kunovac Hodžić, Amaury H. M. J. Triaud, Ruth Angus | Summary: We present TOI-1259Ab, a 1.0 Rjup gas giant planet transiting a 0.71 Rsun K-dwarf on a 3.48 day orbit. The system also contains a bound white dwarf companion TOI-1259B with […]

Exact uniform modulus of continuity and Chung’s LIL for the generalized fractional Brownian motion

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: The generalized fractional Brownian motion (GFBM) $X:={X(t)}_{tge0}$ with parameters $gamma in [0, 1)$ and $alphain left(-frac12+frac{gamma}{2}, , frac12+frac{gamma}{2} right)$ is a centered Gaussian $H$-self-similar process introduced by Pang and Taqqu (2019) as the scaling limit of power-law shot noise […]

The subtlety of Ly-a photons: changing the expected range of the 21-cm signal

Kavli Affiliate: George Efstathiou | First 5 Authors: Itamar Reis, Anastasia Fialkov, Rennan Barkana, , | Summary: We present the evolution of the 21-cm signal from cosmic dawn and the epoch of reionization (EoR) in an upgraded model including three subtle effects of Ly-a radiation: Ly-a heating, CMB heating (mediated by Ly-a photons), and multiple […]

A Novel Modulation Scheme for Homodyne Detection Control

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Danial Shadmany, Benjamin Lane, Vivishek Sudhir, Nergis Mavalvala, | Summary: Controlling the quadrature measured by a homodyne detector is a universal task in continuous-variable quantum optics. However, deriving an error signal that is linear across theentire range of quadrature angles remains an open experimental problem. Here we […]
