Our speaker, Dr. Mertens, discusses in-depth ground-state thermalization due to instantaneous horizon creation in a gravitational setting and its condensed matter analog. Dr. Mertens sheds light on the implications of a sudden change in position-dependent hopping amplitudes in a one-dimensional lattice model, leading to the emergence of a thermal state that accompanies the formation of a synthetic horizon. Throughout the discussion, we unravel the striking parallelism between the resulting temperature for long chains and the Unruh temperature, given that the post-quench Hamiltonian matches the entanglement Hamiltonian of the pre-quench system. We analyze the outgoing radiation from these synthetic horizons and formulate the conditions required for these horizons to behave as a purely thermal source. This podcast episode offers a unique opportunity to learn more about the interplay between quantum-mechanical and gravitational aspects and to understand how these complex ideas might be tested in a laboratory setting. An absolute must-listen for anyone intrigued by the junction of quantum mechanics and gravity and eager to keep up with the latest theoretical developments in the field.

In this episode, we delve into the fascinating world of cosmic metallicity and its role as a unique record of the Universe's total star formation history. Our focus is a groundbreaking paper analyzing oxygen abundance in the nearby system, Markarian 71. This study presents compelling evidence that challenges long-held beliefs in the astrophysics community, particularly in relation to the 'abundance discrepancy factor'.Through a meticulous combination of optical and far-infrared emission line measurements, the study aims to correct for temperature fluctuation effects. The results present an intriguing twist – a stark inconsistency with the metallicity derived from recombination lines. This finding effectively rules out the longstanding hypothesis that the abundance discrepancy factor is primarily due to temperature fluctuations, at least for Markarian 71.As we explore these findings, we'll be discussing the wider implications for our understanding of metallicity across cosmic history. Additionally, we'll look ahead to the potential of recent data from the James Webb Space Telescope and the Atacama Large Millimeter Array, promising to shed further light on this cosmic mystery within the first billion years of the universe.Join us as we journey through the cosmic mists and bring the heavy elements of the Universe into sharper focus. Whether you're a seasoned astrophysicist or simply a stargazer, this episode promises an illuminating exploration of the secrets held in the metals of the cosmos. https://doi.org/10.1038/s41550-023-01953-7
