AI Article Synopsis

  • The study explores how exciton-polaritons in microcavities relax momentum and spin, revealing important quantum properties.
  • It highlights the phenomenon of giant longitudinal-transverse splitting, causing mixing of spin states in polaritons, which leads to observable beats in polarized light emission.
  • The research emphasizes that this mixing is heavily influenced by the bosonic stimulation of polariton scattering, making it a critical factor in understanding the behavior of polaritons.

Article Abstract

We present the quantum theory of momentum and spin relaxation of exciton-polaritons in microcavities. We show that giant longitudinal-transverse splitting of the polaritons mixes their spin states, which results in beats between right- and left-circularly polarized photoluminescence of microcavities, as was recently experimentally observed [Phys. Rev. Lett. 89, 077402 (2002)]]. This effect is strongly sensitive to the bosonic stimulation of polariton scattering.

The development of machine-learning (ML) potentials offers significant accuracy improvements compared to molecular mechanics (MM) because of the inclusion of quantum-mechanical effects in molecular interactions. However, ML simulations are several times more computationally demanding than MM simulations, so there is a trade-off between speed and accuracy. One possible compromise are hybrid machine learning/molecular mechanics (ML/MM) approaches with mechanical embedding that treat the intramolecular interactions of the ligand at the ML level and the protein-ligand interactions at the MM level.

Kolmogorov-Hinze Scales in Turbulent Superfluids.

Phys Rev Lett

December 2024

Department of Engineering Science, University of Electro-Communications, Tokyo 182-8585, Japan.

When a two-component mixture of immiscible fluids is stirred, the fluids are split into smaller domains with more vigorous stirring. We numerically investigate the sizes of such domains in a fully developed turbulent state of a two-component superfluid stirred with energy input rate ε. For the strongly immiscible condition, the typical domain size is shown to be proportional to ε^{-2/5}, as predicted by the Kolmogorov-Hinze theory in classical fluids.

Black Box Work Extraction and Composite Hypothesis Testing.

Phys Rev Lett

December 2024

Department of Basic Science, The University of Tokyo, 3-8-1 Komaba, Meguro-ku, Tokyo 153-8902, Japan.

Work extraction is one of the most central processes in quantum thermodynamics. However, the prior analysis of optimal extractable work has been restricted to a limited operational scenario where complete information about the initial state is given. Here, we introduce a general framework of black box work extraction, which addresses the inaccessibility of information on the initial state.

A key objective in nuclear and high-energy physics is to describe nonequilibrium dynamics of matter, e.g., in the early Universe and in particle colliders, starting from the standard model of particle physics.

Developing high-precision models of the nuclear force and propagating the associated uncertainties in quantum many-body calculations of nuclei and nuclear matter remain key challenges for ab initio nuclear theory. In this Letter, we demonstrate that generative machine learning models can construct novel instances of the nucleon-nucleon interaction when trained on existing potentials from the literature. In particular, we train the generative model on nucleon-nucleon potentials derived at second and third order in chiral effective field theory and at three different choices of the resolution scale.
