skewness kurtosis and the fifth and sixth Order Cumulants of net baryon number distributions from lattice qcd confront high statistics star data
Physical Review D, 2020Co-Authors: A Bazavov, Dennis Bollweg, P Enns, Jishnu Goswami, P Hegde, Olaf Kaczmarek, Frithjof Karsch, Hengtong Ding, Rasmus LarsenAbstract:We present new results on up to sixth-Order Cumulants of net baryon-number fluctuations at small values of the baryon chemical potential, ${\ensuremath{\mu}}_{B}$, obtained in lattice QCD calculations with physical values of light and strange quark masses. Representing the Taylor expansions of higher-Order Cumulants in terms of the ratio of the two lowest-Order Cumulants, ${M}_{B}/{\ensuremath{\sigma}}_{B}^{2}={\ensuremath{\chi}}_{1}^{B}(T,{\ensuremath{\mu}}_{B})/{\ensuremath{\chi}}_{2}^{B}(T,{\ensuremath{\mu}}_{B})$, allows for a parameter-free comparison with data on net proton-number Cumulants obtained by the STAR Collaboration in the Beam Energy Scan at RHIC. We show that recent high-statistics data on skewness and kurtosis ratios of net proton-number distributions, obtained at a beam energy $\sqrt{{s}_{NN}}=54.4\text{ }\text{ }\mathrm{GeV}$, agree well with lattice QCD results on Cumulants of net baryon-number fluctuations close to the pseudocritical temperature, ${T}_{pc}({\ensuremath{\mu}}_{B})$, for the chiral transition in QCD. We also present first results from a next-to-leading-Order expansion of fifth- and sixth-Order Cumulants on the line of the pseudocritical temperatures.

skewness kurtosis and the fifth and sixth Order Cumulants of net baryon number distributions from lattice qcd confront high statistics star data
Physical Review D, 2020Co-Authors: A Bazavov, Dennis Bollweg, H T Ding, P Enns, Jishnu Goswami, P Hegde, Olaf Kaczmarek, Frithjof Karsch, Rasmus Larsen, Swagato MukherjeeAbstract:We present new results on up to sixth-Order Cumulants of net baryon-number fluctuations at small values of the baryon chemical potential, I¼B, obtained in lattice QCD calculations with physical values of light and strange quark masses. Representing the Taylor expansions of higher-Order Cumulants in terms of the ratio of the two lowest-Order Cumulants, MB/I�B2=I�1B(T,I¼B)/I�2B(T,I¼B), allows for a parameter-free comparison with data on net proton-number Cumulants obtained by the STAR Collaboration in the Beam Energy Scan at RHIC. We show that recent high-statistics data on skewness and kurtosis ratios of net proton-number distributions, obtained at a beam energy sNN=54.4 GeV, agree well with lattice QCD results on Cumulants of net baryon-number fluctuations close to the pseudocritical temperature, Tpc(I¼B), for the chiral transition in QCD. We also present first results from a next-to-leading-Order expansion of fifth- and sixth-Order Cumulants on the line of the pseudocritical temperatures.

High-Order Cumulants in the counting statistics of asymmetric quantum dots
Applied Physics Letters, 2010Co-Authors: Christian Fricke, Frank Hohls, Nandhavel Sethubalasubramanian, Lukas Fricke, Rolf J. HaugAbstract:Measurements of single electron tunneling through a quantum dot (QD) using a quantum point contact as charge detector have been performed for very long time traces with very large event counts. This large statistical basis is used for a detailed examination of the counting statistics for varying symmetry of the QD system. From the measured statistics we extract high Order Cumulants describing the distribution. Oscillations of the high Order Cumulants are observed when varying the symmetry. We compare this behavior to the observed oscillation in time dependence and show that the variation in both system variables lead to the same kind of oscillating response.

universal oscillations of high Order Cumulants
International Conference on Noise and Fluctuations, 2009Co-Authors: Christian Flindt, Christian Fricke, Frank Hohls, Tomas Novotny, Karel Netocny, Tobias Brandes, Rolf J. HaugAbstract:We discuss our recent measurement of high‐Order Cumulants of charge transport through a quantum dot. The Cumulants were found to oscillate as functions of measurement time before reaching their linear‐in‐time asymptotics. A theoretical analysis revealed that such oscillations in fact constitute a universal phenomenon: for a large class of stochastic processes the high‐Order Cumulants are predicted to oscillate as functions of basically any parameter. Here, we give an overview of these recent results, provide an outlook on future applications of our findings, and formulate a number of open questions.
