Probing parity violation with the four-point correlation function of BOSS galaxies [PDF]
Physical Review D, 2022 Parity-violating physics in the early Universe can leave detectable traces in late-time observables. Whilst vector- and tensor-type parity-violation can be observed in the $B$-modes of the cosmic microwave background, scalar-type signatures are visible ...

Journal of High Energy Physics, 2023 We generalize the world line EFT formalism to account for parity violating finite size effects. Results are presented for potentials and radiating moments of a binary inspiral for the parity conserving sector, and agreement is found with, previous ...

Parity-odd and even trispectrum from axion inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 The four-point correlation function of primordial scalar perturbations has parity-even and parity-odd contributions and the parity-odd signal in cosmological observations is opening a novel window to look for new physics in the inflationary epoch.

, 2020 In the present work, a new method for solving a strong nonlinear oscillator equation of the form x + F(x) = 0, where F(−x) = −F(x), is carried out. This method consists of approximating function F(x) by means of a suitable Chebyshev polynomial: F(x) ≈ P ...

Unbroken versus broken mirror world: a tale of two vacua [PDF]
, 2000 If the Lagrangian of nature respects parity invariance then there are two distinct possibilities: either parity is unbroken by the vacuum or it is spontaneously broken.

Experimental signature of the parity anomaly in a semi-magnetic topological insulator [PDF]
Nature Physics, 2021 A three-dimensional (3D) topological insulator features a 2D surface state consisting of a single linearly dispersive Dirac cone1–3. Under broken time-reversal symmetry, the single Dirac cone is predicted to cause half-integer quantization of Hall ...

Measuring the nuclear magnetic quadrupole moment in heavy polar molecules
Frontiers in Physics, 2023 Theories that extend the Standard Model of particle physics often introduce new interactions that violate charge-parity (CP) symmetry. Charge-parity-violating effects within an atomic nucleus can be probed by measuring its nuclear magnetic quadrupole ...

Searching for T-Violating, P-Conserving New Physics with Neutrons [PDF]
, 2000 The observance of parity conserving time reversal violation in light quark systems could signal the presence of physics beyond the Standard Model. I discuss the implications of low-energy time reversal tests for the existence of such T-violating, P ...

Colliders and ghosts: Constraining inflation with the parity-odd galaxy four-point function [PDF]
Physical Review D, 2022 Could new physics break the mirror symmetry of the Universe? Utilizing recent measurements of the parity-odd four-point correlation function of BOSS galaxies, we probe the physics of inflation by placing constraints on the amplitude of a number of parity-

Chiral Photocurrent in Parity-Violating Magnet and Enhanced Response in Topological Antiferromagnet
Physical Review X, 2021 Rectified electric current induced by irradiating light, a so-called photocurrent, is an established phenomenon in optoelectronic physics. In this paper, we present a comprehensive classification of the photocurrent response arising from the parity ...
