State-to-State Cosmology: A New View on the Cosmological Arrow of Time and the Past Hypothesis
Foundations of physics, 2021Cosmological boundary conditions for particles and fields are often discussed as a Cauchy problem, in which configurations and conjugate momenta are specified on an “initial” time slice.

Seeing the Arrow of Time in Large Multimodal Models
arXiv.orgThe Arrow of Time (AoT)-time's irreversible flow shaping physical events-is fundamental to video comprehension, yet remains a significant challenge for modern large multimodal models (LMMs).

Physics Bulletin, 1971
I would like to comment on the recent article by Dr P C W Davies (April 1971 p211), in which the author discusses the direction of time's arrow. The concept of direction implies a reference frame relative to which direction can be determined.

Testing the arrow of time at the cosmo collider
Journal of Cosmology and Astroparticle PhysicsNormal particles carry a microscopic arrow of causality. Lee-Wick ghosts carry the reversed arrow, mediating characteristic collider signals in flat space: opposite-sign scattering amplitudes that violate positivity bounds; acausality on time scales set ...
