  • Author(s): Tyler Gorda, Juuso Österman, and Saga Säppi Within the framework of the imaginary time formalism applied to systems at zero temperature but finite density, the authors investigate whether the order of integration, namely the spatial momentum integration is performed before that of the temporal momentum or vice versa, matters. They show that the former yields results consistent with those for nonzero but very low values of the temperature...
  • Author(s): Bernardo Porto Veronese and Carsten Gundlach The authors numerically study the interactions between scalar fields and gravitational waves in the context of gravitational collapse at the threshold of black hole formation in 4+1 dimensions. They find evidence for the existence of a co-dimension two attractor in the dynamical systems picture. [Phys. Rev. D 106, 104044] Published Tue Nov 22, 2022
  • Author(s): Oleksandr Tomalak, Qing Chen, Richard J. Hill, Kevin S. McFarland, and Clarence Wret Neutrino beam experiments to measure neutrino cross sections on nuclear targets are part of a major experimental program. In this paper, the authors compute radiative QED corrections to neutrino-nucleus scattering using effective field theory methods that separate perturbative QED soft and collinear contributions from hard nuclear ones. Applications...
  • Author(s): Chiung Hwang, Sara Pasquetti, and Matteo Sacchi The authors develop an algorithm for a field theoretical implementation of mirror symmetry. This is based on the so-called quiver representation of certain N=1 supersymmetric theories and is a non-abelian generalization of the piecewise dualization of three-dimensional abelian theories. Extensions of this local field-theoretic operations to non-supersymmetric theories are expected. ...
  • Author(s): David Ellis, David J. E. Marsh, Benedikt Eggemeier, Jens Niemeyer, Javier Redondo, and Klaus Dolag Asteroid-sized clumps of a dark matter candidate known as an axion could be detectable in a gravitational-microlensing survey. [Phys. Rev. D 106, 103514] Published Tue Nov 15, 2022
  • Author(s): Tousif Islam, Scott E. Field, Scott A. Hughes, Gaurav Khanna, Vijay Varma, Matthew Giesler, Mark A. Scheel, Lawrence E. Kidder, and Harald P. Pfeiffer Gravitational waveforms obtained using numerical relativity (NR) are computationally expensive and slow. Surrogate models provide an alternative to full NR by extrapolating from the point-particle regime of high-mass ratio binary waveforms calibrated to NR to much smaller mass ratios...
  • Author(s): Valentin Deliyski, Galin Gyulchev, Petya Nedkova, and Stoytcho Yazadjiev Predictions indicate that wormholes and black holes may have nearly identical polarized light spectra, making these astrophysical objects difficult to distinguish.
