One previously unexplored configuration for ultracold ensembles is that of a bubble or shell, where trapped atoms are confined in the vicinity of a spherical or ellipsoidal surface. Such a quantum system could offer new collective modes, topologically-sensitive behavior of quantized vortices, self-interference and shell collapse, as well as the exploration of trapped ultracold systems with mm-scale spatial extent. While techniques for the generation of bubble-shaped traps have been known since 2001, terrestrial gravity has thus far limited the convenient observation of ultracold bubbles. With the construction of the NASA Cold Atom Lab (CAL) facility and its subsequent delivery in 2018 to the International Space Station (ISS) and commissioning as an orbital BEC user facility, experimental atomic physics schemes that require a sustained microgravity environment are now possible. I will review CAL observations of trapped bubbles of ultracold atoms, including a variety of bubble-trap configurations that are possible with this apparatus. I will also discuss the thermodynamics of ultracold bubbles and review open questions being explored in the ongoing second science run of CAL aboard ISS, which feature improved bubble aspect ratios and filling as well as improved imaging; I will also review upcoming changes to the CAL facility, recent progress made with shell structures in terrestrial laboratories, and the bubble-making potential of the Einstein Elevator.

The notion of topology is however ususally associated with ground states of (many-body)-Hamiltonians, which are pure. So what is left of it at finite temperatures and can topological protection be extended to non-equilibrium steady states (NESS) of open systems? Can suitable observables be constructed that preserve the integrity of topological invariants for mixed states and what are measurable consequences of their existence? Can we classify the topology of finite-temperature and NESS using generalized symmetries?

FYI -------- Weitergeleitete Nachricht -------- Betreff: [BridgeQG COST Action] Fwd: School of Quantum Foundations: Speakable and Unspeakable, August 18–27, 2025, University of Split, Croatia Datum: Wed, 14 May 2025 13:47:41 +0200 Von: Giulia Gubitosi <giulia.gubitosi(a)unina.it> An: Giulia Gubitosi <giulia.gubitosi(a)gmail.com> Kopie (CC): Sandro Donadi <s.donadi(a)qub.ac.uk> Dear BridgeQG members, please find below the announcement of a school that might be of interest for some of you. Best regards, Giulia Gubitosi Chair of COST Action BridgeQG PS. Please feel free to advertise this COST Action to colleagues who might be interested in joining. Application for membership can be done through the website https://www.cost.eu/actions/CA23130/. ======= Dear all, We are pleased to announce the *School of Quantum Foundations: Speakable and Unspeakable*, a ten-day event dedicated to the exploration of fundamental questions in quantum mechanics. *Dates:* August 18–27, 2025 *Location:* University of Split, Croatia *Website and Application:* https://www.qmts.it/conferences/school-of-quantum-foundations-speakable-and… <https://www.qmts.it/conferences/school-of-quantum-foundations-speakable-and…> The school is intended for graduate students, postdoctoral researchers, and early-career scientists interested in foundational questions in quantum theory. It will feature lectures and in-depth discussions led by the following invited speakers: * *Tim Maudlin* (NYU) * *Ward Struyve* (KU Leuven) * *Angelo Bassi* (University of Trieste) * *Sandro Donadi* (Queen’s University Belfast) * *Matteo Carlesso* (University of Trieste) Topics will include quantum nonlocality, Bohmian mechanics, collapse models, decoherence, optomechanics and related foundational issues. *Application deadline:* 30th June 2025 Participation is limited, and early applications are strongly encouraged. Please feel free to share this announcement with interested colleagues and students. The Organizers
