Holographic Complexity Equals Which Action?
Kanato Goto, Hugo Marrochio, Robert C. Myers +2
We revisit the complexityaction proposal for charged black holes. We investigate the complexity for a dyonic black hole, and we find the surprising feature that the late-time gr…
An Accurate Analytic Model for the Thermal Sunyaev-Zel'dovich One-Point PDF
Leander Thiele, J. Colin Hill, Kendrick M. Smith
Non-Gaussian statistics of late-time cosmological fields contain information beyond that captured in the power spectrum. Here we focus on one such example: the one-point probabilit…
Open source software in quantum computing
Mark Fingerhuth, Tomáš Babej, Peter Wittek
Open source software is becoming crucial in the design and testing of quantum algorithms. Many of the tools are backed by major commercial vendors with the goal to make it easier t…
Cosmological beam dump: constraints on dark scalars mixed with the Higgs boson
Anthony Fradette, Maxim Pospelov, Josef Pradler +1
Precision cosmology provides a sensitive probe of extremely weakly coupled states due to thermal freeze-in production, with subsequent decays impacting physics during well-tested c…
Probing neutron star structure via f-mode oscillations and damping in dynamical spacetime models
Shawn Rosofsky, Roman Gold, Cecilia Chirenti +2
Gravitational wave and electromagnetic observations can provide new insights into the nature of matter at supra-nuclear densities inside neutron stars. Improvements in electromagne…
Time-varying neutrino mass from a supercooled phase transition: current cosmological constraints and impact on the - plane
Christiane S. Lorenz, Lena Funcke, Erminia Calabrese +1
In this paper we investigate a time-varying neutrino mass model, motivated by the mild tension between cosmic microwave background (CMB) measurements of the matter fluctuations and…
