In recent years, the landscape of scientific publishing has witnessed a profound transformation with the rising popularity of Artificial Intelligence (AI) chatbots that are based on large language models. This talk explores the phenomenon from the perspective of a journal editor, offering insights into the implications, challenges, and opportunities presented by the integration of AI chatbots in scholarly communication. Amid the proliferation of AI chatbots, ethical considerations regarding data privacy, algorithmic bias, and transparency loom large, necessitating careful deliberation and responsible deployment. The talk will emphasize the responsibilities of manuscript authors, reviewers and editors in navigating the evolving landscape of AI-driven scientific publishing, fostering innovation while upholding scholarly integrity and ethical standards. Before the presentation on scientific publishing aspects, I will also briefly introduce Physical Review B and how the journal has evolved.

Long-lived particles (LLPs) have attracted considerable attention in the past few years, in particular because several new "far" detectors have been proposed at the LHC. In this talk, I will discuss heavy neutral leptons (a.k.a. right-handed neutrinos). Due to their connection to neutrino mass generation HNLs are well-motivated LLPs. After introducing minimal HNLs and studying prospects for discovery at the LHC, I will turn to HNLs in effective field theory (EFT). EFTs are well suited to study non-minimal extension of the SM in the absence of new resonances at the LHC. The effects of non-renormalizable operators on prospects for HNLs discovery will be presented in some detail.

Coherence properties are central to quantum systems and are at the heart of phenomena such as superconductivity. Here we study coherence properties of an ultracold Bose gas in a two-dimensional optical lattice across the thermal phase transition [1]. To infer the phase coherence and phase fluctuation profile, we use direct matter-wave imaging [2] of higher Talbot revivals as well as a new phase microscope based on a site-resolved mapping of phase fluctuations to density fluctuations during matter-wave imaging. We observe the algebraic decay of the phase correlations in the superfluid phase and a linear temperature increase of the exponent. These techniques will also allow studying coherence properties in strongly-correlated quantum systems with full spatial resolution. References [1] J. C. Brüggenjürgen, M. S. Fischer, C.
