Generative Modelling With Inverse Heat Dissipation [PDF]
International Conference on Learning Representations, 2022 While diffusion models have shown great success in image generation, their noise-inverting generative process does not explicitly consider the structure of images, such as their inherent multi-scale nature.

Colloquium : Planckian dissipation in metals [PDF]
Reviews of Modern Physics, 2021 We review the appearance of the Planckian time τPl = ~/(kBT ) in both conventional and unconventional metals. We give a pedagogical discussion of the various different timescales (quasiparticle, transport, many-body) that characterize metals, emphasizing

PT-symmetric non-Hermitian quantum many-body system using ultracold atoms in an optical lattice with controlled dissipation [PDF]
Progress of Theoretical and Experimental Physics, 2020 We report our realization of a parity–time (PT)-symmetric non-Hermitian many-body system using cold atoms with dissipation. After developing a theoretical framework on PT-symmetric many-body systems using ultracold atoms in an optical lattice with ...

Non-stationary coherent quantum many-body dynamics through dissipation [PDF]
Nature Communications, 2018 The assumption that quantum systems relax to a stationary state in the long-time limit underpins statistical physics and much of our intuitive understanding of scientific phenomena.

Quantifying dissipation using fluctuating currents [PDF]
Nature Communications, 2018 Systems coupled to multiple thermodynamic reservoirs can exhibit nonequilibrium dynamics, breaking detailed balance to generate currents. To power these currents, the entropy of the reservoirs increases. The rate of entropy production, or dissipation, is

Dissipation-induced structural instability and chiral dynamics in a quantum gas [PDF]
Science, 2019 Chirality by dissipation Quantum many-body systems can display exotic dynamics in the presence of dissipation. Dogra et al. studied such dynamics in a system consisting of an atomic Bose-Einstein condensate located in an optical cavity and exposed to a ...

Ultra-coherent nanomechanical resonators via soft clamping and dissipation dilution [PDF]
Nature Nanotechnology, 2016 The small mass and high coherence of nanomechanical resonators render them the ultimate mechanical probe, with applications ranging from protein mass spectrometry and magnetic resonance force microscopy, to quantum optomechanics. A notorious challenge in
