    Quantum refrigerators – the quantum thermodynamics of cooling Bose gases 

    Deffner, Sebastian (Quantum, 2019-08-13)
    Thumbnail

    Quantum speed limits and the maximal rate of entropy production 

    Deffner, Sebastian (2019-10-16)
    The Bremermann-Bekenstein bound sets a fundamental upper limit on the rate with which information can be processed. However, the original treatment heavily relies on cosmological properties and plausibility arguments. In ...

    Quantum speed limits: from Heisenberg's uncertainty principle to optimal quantum control 

    Deffner, Sebastian; Campbell, Steve (IOP, 2017-10-10)
    One of the most widely known building blocks of modern physics is Heisenberg's indeterminacy principle. Among the different statements of this fundamental property of the full quantum mechanical nature of physical reality, ...

    Classical and Quantum Shortcuts to Adiabaticity for Scale-Invariant Driving 

    Deffner, Sebastian; Jarzynski, Christopher; Campo, Adolfo del (American Physical Society (APS), 2014-04-22)
    A shortcut to adiabaticity is a driving protocol that reproduces in a short time the same final state that would result from an adiabatic, infinitely slow process. A powerful technique to engineer such shortcuts relies on ...

    Trade-Off Between Speed and Cost in Shortcuts to Adiabaticity 

    Campbell, Steve; Deffner, Sebastian (American Physical Society (APS), 2017-03-08)
    Achieving effectively adiabatic dynamics is a ubiquitous goal in almost all areas of quantum physics. Here, we study the speed with which a quantum system can be driven when employing transitionless quantum driving. As a ...

    Energy–time uncertainty relation for driven quantum systems 

    Deffner, Sebastian; Lutz, Eric (IOP, 2013-07-29)
    We derive generalizations of the energy–time uncertainty relation for driven quantum systems. Using a geometric approach based on the Bures length between mixed quantum states, we obtain explicit expressions for the quantum ...

    Nonequilibrium work distribution of a quantum harmonic oscillator 

    Deffner, Sebastian; Lutz, Eric (American Physical Society (APS), 2008-02-27)
    We calculate analytically the work distribution of a quantum harmonic oscillator with arbitrary time-dependent angular frequency. We provide detailed expressions for the work probability density for adiabatic and nonadiabatic ...

    Information Processing and the Second Law of Thermodynamics: An Inclusive, Hamiltonian Approach 

    Deffner, Sebastian; Jarzynski, Christopher (American Physical Society (APS), 2013-10-17)
    We obtain generalizations of the Kelvin-Planck, Clausius, and Carnot statements of the second law of thermodynamics for situations involving information processing. To this end, we consider an information reservoir ...

    Thermodynamic universality of quantum Carnot engines 

    Gardas, Bartłomiej; Deffner, Sebastian (American Physical Society (APS), 2015-10-12)
    The Carnot statement of the second law of thermodynamics poses an upper limit on the efficiency of all heat engines. Recently, it has been studied whether generic quantum features such as coherence and quantum entanglement ...

    Quantum Speed Limit for Non-Markovian Dynamics 

    Deffner, Sebastian; Lutz, Eric (American Physical Society (APS), 2013-07-03)
    We derive a Margolus-Levitin-type bound on the minimal evolution time of an arbitrarily driven open quantum system. We express this quantum speed limit time in terms of the operator norm of the nonunitary generator of the ...
