Optimizing the Evolution of Perturbations in the $Λ$CDM Universe

Kavli Affiliate: Anthony Challinor | First 5 Authors: Nicholas Choustikov, Zvonimir Vlah, Anthony Challinor | Summary: Perturbation theory is a powerful tool for studying large-scale structure formation in the universe and calculating observables such as the power spectrum or bispectrum. However, beyond linear order, typically this is done by assuming a simplification in the time-dependence […]

Colloquium: Quantum and Classical Discrete Time Crystals

Kavli Affiliate: Frank Wilczek | First 5 Authors: Michael P. Zaletel, Mikhail Lukin, Christopher Monroe, Chetan Nayak, Frank Wilczek | Summary: The spontaneous breaking of time translation symmetry has led to the discovery of a new phase of matter – the discrete time crystal. Discrete time crystals exhibit rigid subharmonic oscillations, which result from a […]

Exploring Ultralight Scalar Assistance in Sterile Neutrino Dark Matter: Cold Spectrum and Unusual X/Gamma-ray Signatures

Kavli Affiliate: Jia Liu | First 5 Authors: Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang | Summary: We present a scalar-driven sterile neutrino production model where the interaction with the ultralight scalar field modifies the oscillation production of sterile neutrinos in the early universe. The model effectively suppresses the production of sterile neutrinos at […]
