Evidence for the existence of dark matter abounds in the study of astrophysical phenomena. Nevertheless, a dark matter candidate has yet to be explicitly identified. Direct detection of such a particle would point to physics beyond the Standard Model. The Axion Dark Matter eXperiment (ADMX) is searching for a wave-like dark matter candidate in the form of an axion. Such a candidate could resolve not only the dark matter problem, but also the strong CP problem.
Understanding gravity in the framework of quantum mechanics is one of the great challenges in modern physics. Along this line, a prime question is to find whether gravity is a quantum entity subject to the rules of quantum mechanics. It is fair to say that there are no feasible ideas yet to test the quantum coherent behaviour of gravity directly in a laboratory experiment. Here, we introduce an idea for such a test based on the principle that two objects cannot be entangled without a quantum mediator.
Noble liquid time projection chambers are ubiquitously used to search for rare events such
as neutrinoless double beta decay or dark matter interactions. A detailed understanding of
light and charge transport in liquid xenon is of the utmost importance when modeling the
performance of these experiments.
In this talk I will present the design and physics reach of the proposed nEXO experiment,

Nuclei with equal number of baryons but varying proton number (isobars) have many commonalities, but differ in both electric charge and nuclear structure. Relativistic collisions of such isobars provide unique opportunities to study the variation of the magnetic field, provided the nuclear structure is well understood. In this Letter we simulate collisions using several state-of-the-art parametrizations of the Zr and Ru isobars and show that a comparison with the exciting STAR measurement arXiv:2109.00131 of ultrarelativistic collisions can uniquely identify the structure of both isobars.
Stress-induced voiding (SIV) is amongst the most commonly reported defects in metallic systems used as interconnects in electronic devices. Apart from the development of novel materials, these degradation effects are crucial for the understanding of the properties of nanocrystals. Hydrogen along with other impurities like O, S and C, play a crucial role in metal embrittlement and can be detrimental to the performance of these devices. In addition, the inclusion of metallic dopants is expected to inhibit the effects of non-metallic impurities.
Measurements of the substructure of high-momentum jets produced in proton-proton (pp) collisions give insight into fundamental aspects of QCD, from the production of highly virtual partons, to their subsequent radiation and hadronization. Additionally, once the evolution of jets in vacuum is calibrated, it is possible to study potential modification to jet substructure due to interaction with the cold nuclear medium present in proton-gold (pAu) collisions.
