© 2017 American Physical Society. We identify a universal indicator for the impact of coherence on periodically driven quantum devices by dividing their power output into a classical contribution and one stemming solely from superpositions. Specializ... Read More about Universal Coherence-Induced Power Losses of Quantum Heat Engines in Linear Response.

Experimental Determination of Dynamical Lee-Yang Zeros (2017)
Journal Article
Brandner, K., Maisi, V. F., Pekola, J. P., Garrahan, J. P., & Flindt, C. (2017). Experimental Determination of Dynamical Lee-Yang Zeros. Physical Review Letters, 118(18), Article 180601. https://doi.org/10.1103/physrevlett.118.180601

Statistical physics provides the concepts and methods to explain the phase behavior of interacting many-body systems. Investigations of Lee-Yang zeros - complex singularities of the free energy in systems of finite size - have led to a unified unders...
