Universal non-Hermitian flow in one-dimensional PT-symmetric quantum criticalities

Kavli Affiliate: Ke Wang | First 5 Authors: Xin-Chi Zhou, Ke Wang, , , | Summary: The critical point of a topological phase transition is described by a conformal field theory (CFT), where the finite-size corrections to the ground state energy are uniquely related to its central charge. We study the finite-size scaling of the […]

Constraints on conformal ultralight dark matter couplings from the European Pulsar Timing Array

Kavli Affiliate: Lijing Shao | First 5 Authors: Clemente Smarra, Adrien Kuntz, Enrico Barausse, Boris Goncharov, Diana López Nacir | Summary: Millisecond pulsars are extremely precise celestial clocks: as they rotate, the beamed radio waves emitted along the axis of their magnetic field can be detected with radio telescopes, which allows for tracking subtle changes […]

Dynamical Freezing in Exactly Solvable Models of Driven Chaotic Quantum Dots

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Haoyu Guo, Rohit Mukherjee, Debanjan Chowdhury, , | Summary: The late-time equilibrium behavior of generic interacting models is determined by the coupled hydrodynamic equations associated with the globally conserved quantities. In the presence of an external time-dependent drive, non-integrable systems typically thermalize to an effectively infinite-temperature state, […]

The Simons Observatory: Combining cross-spectral foreground cleaning with multi-tracer $B$-mode delensing for improved constraints on inflation

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Emilie Hertig, Kevin Wolz, Toshiya Namikawa, Antón Baleato Lizancos, Susanna Azzoni | Summary: The Simons Observatory (SO), due to start full science operations in early 2025, aims to set tight constraints on inflationary physics by inferring the tensor-to-scalar ratio $r$ from measurements of CMB polarization $B$-modes. Its […]

The Atacama Cosmology Telescope: Reionization kSZ trispectrum methodology and limits

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Niall MacCrann, Frank J. Qu, Toshiya Namikawa, Boris Bolliet, Hongbo Cai | Summary: Patchy reionization generates kinematic Sunyaev-Zeldovich (kSZ) anisotropies in the cosmic microwave background (CMB). Large-scale velocity perturbations along the line of sight modulate the small-scale kSZ power spectrum, leading to a trispectrum (or four-point function) […]
