  3. 157. How much SYK is enough for Quantum Chaos?
    Pratik Nandy (VUB)

    We propose a two-body variant of bosonic SYK-type models that represents a minimal setting in which chaotic dynamics emerge, a phenomenon we refer to as quadratic quantum chaos. In contrast to integrable quadratic fermionic systems, the corresponding hard-core bosonic models exhibit genuine many-body chaos. We diagnose this behaviour using spectral statistics and multiple probes of operator...

    In a mixture of two Bose-Einstein condensates, the interactions can be tuned such that self bound objects called quantum droplets appear. Whereas the ground states of such quantum droplets at finite temperature have been studied for three- and one-dimensional configurations, the possible fragmentation of these droplets has so far not been considered in these studies. In this work we show that...

  6. 160. Extracting average properties of random spin chains with translationally invariant tensor networks
    Kevin Vervoort (Ghent University)
    05/06/2026, 10:35

    Disordered quantum spin chains are interesting systems as they can behave very differently from their clean counterparts. However simulating these systems pose signifciant challenges. First translation symmetry is broken when one considers a specific disorder realization, Secondly if one wants to study averaged observables it is necessary to average over many different disorder realization. In...

  7. 165. Metastable strings at PTA: classical stability analysis
    Maxime Grandjean (VUB)
    05/06/2026, 10:42

    Metastable strings can arise because of a two-step symmetry breaking chain of the type $SU(2)\to U(1)\to 1$. These strings can decay via quantum tunnelling through the nucleation of monopole anti-monopole pairs, and have recently been considered as candidates for explaining the gravitational-wave background observed by pulsar timing arrays. In our work, we study the classical stability of such...
