  • Adiabatic spin cooling using high-spin Fermi gases 
    Colomé-Tatché, Maria; Klempt, Carsten; Santos, Luis; Vekua, Teimuraz (Bristol : IOP Publishing Ltd., 2011)
    Spatial entropy redistribution plays a key role in adiabatic cooling of ultra-cold lattice gases. We show that high-spin fermions with a spatially variable quadratic Zeeman coupling may allow for the creation of an inner ...
  • Bounded Entanglement Entropy in the Quantum Ising Model 
    Grimmett, Geoffrey R.; Osborne, Tobias J.; Scudo, Petra F. (Heidelberg : Springer, 2020)
    A rigorous proof is presented of the boundedness of the entanglement entropy of a block of spins for the ground state of the one-dimensional quantum Ising model with sufficiently strong transverse field. This is proved by ...
  • Jones index, secret sharing and total quantum dimension 
    Fiedler, Leander; Naaijkens, Pieter; Osborne, Tobias J. (Bristol : Institute of Physics Publishing, 2017)
    We study the total quantum dimension in the thermodynamic limit of topologically ordered systems. In particular, using the anyons (or superselection sectors) of such models, we define a secret sharing scheme, storing ...
  • Multi-anionic and -cationic compounds: New high entropy materials for advanced Li-ion batteries 
    Wang, Qingsong; Sarkar, Abishek; Wang, Di; Velasco, Leonardo; Azmi, Raheleh; Bhattacharya, Subramshu S.; Bergfeldt, Thomas; Düvel, Andre; Heitjans, Paul; Brezesinski, Torsten; Hahn, Horst; Breitung, Ben (Cambridge : Royal Society of Chemistry, 2019)
    In the present work, a new class of high entropy materials for energy storage applications is introduced. Multi-anionic and -cationic compounds are prepared by facile mechanochemistry using a recently designed multi-cationic ...
  • Thermodynamics and the structure of quantum theory 
    Krumm, M.; Barnum, H.; Barrett, J.; Müller, M.P. (Bristol : Institute of Physics Publishing, 2017)
    Despite its enormous empirical success, the formalism of quantum theory still raises fundamental questions: why is nature described in terms of complex Hilbert spaces, and what modifications of it could we reasonably expect ...
