The examination of parity symmetry in gravitational interactions has drawn increasing attention. Although Einstein’s General Relativity is parity-conserved, numerous theories parity-violating (PV) gravity different frameworks have recently been proposed for motivations. In this review, we briefly summarize the recent progress these theories, and focus on observable effects PV terms waves (GWs), which are mainly reflected difference between left-hand right-hand polarization modes. We...

Abstract We revisit the gravitational lensing of light or waves by a Schwarzschild black hole in geometric optics. Rather than focusing on single massless particle, we investigate collective behavior congruence rays, described geodesic deviation equation (GDE). By projecting GDE onto Newman-Penrose tetrad, decouple and find an analytical Dyson-like series solution weak deflection thin lens limits. Using this solution, analyze evolution cross-sectional area axis ratio. Finally, reproduce...

We calculate the gravitational waveform radiated from spinning black holes (BHs) binary in dynamical Chern-Simons (dCS) gravity. The equation of motion (EOM) spinining BHs is derived based on modified Mathisson-Papapetrou-Dixon for spin-aligned circular orbits. leading-order effects induced by dCS theory contains spin-spin interaction and monopole-quadrupole interaction, which influence both EOM system corresponding at second post-Newtonian (PN) order (i.e., 2PN order). After reporting...

Despite their remarkable performance, the development of Large Language Models (LLMs) faces a critical challenge in scalable oversight: providing effective feedback for tasks where human evaluation is difficult or LLMs outperform humans. While there growing interest using critique, current approaches still rely on annotations more powerful models, leaving issue enhancing critique capabilities without external supervision unresolved. We introduce SCRIT (Self-evolving CRITic), framework that...

Critiques are important for enhancing the performance of Large Language Models (LLMs), enabling both self-improvement and constructive feedback others by identifying flaws suggesting improvements.
