Our papers are the official record of our discoveries. They allow others to build on and apply our work. Each paper is the result of many months of research, so we make a special effort to make them clear, beautiful and inspirational, and publish them in leading journals.

  • On defining the Hamiltonian beyond quantum theory

    ODO. DahlstenDBAG Foundations of Physics

    A Hamiltonian recipe

    An explicit recipe for defining the Hamiltonian in general probabilistic theories, which have the potential to generalise quantum theory.

  • Maximum one-shot dissipated work from Rényi divergences

    ODO. DahlstenNHAGVV Physical Review E

    One-shot statistic

    One-shot analogs of fluctuation-theorem results help unify these two approaches for small-scale, nonequilibrium statistical physics.

  • Quantum generalisation of feedforward neural networks

    ODO. DahlstenKWHKRGMK Nature Quantum Information

    Quantum neural networks

    We generalise neural networks into a quantum framework, demonstrating the possibility of quantum auto-encoders and teleportation.

  • Organic molecule fluorescence as an experimental test-bed for quantum jumps in thermodynamics

    ODO. DahlstenCBTFVV Proceedings of the Royal Society A

    Quantum thermodynamics

    Spectroscopy experiments show that energy shifts due to photon emission from individual molecules satisfy a fundamental quantum relation.
