Event-by-event hydrodynamics for heavy-ion collisions

We compare v2/{\epsilon}2 and v3/{\epsilon}3 from single-shot and event-by-event (2+1)-dimensional hydrodynamic calculations and discuss the validity of using single-shot calculations as substitutes for event-by-event calculations. Further we present a proof- of-concept calculation demonstrating that v2 and v3 together can be used to strongly reduce initial condition ambiguities.Comment: 3 pages, 2 figures.

Event-by-event Hydrodynamic Simulations for Relativistic Heavy-ion Collisions

In this thesis, I show my Ph.D. work on event-by-event hydrodynamic simulations for relativistic heavy-ion collision. I show that event-by-event hydrodynamic simulations have become an indispensable tool for studying relativistic heavy-ion collisions and how it can be used to explain many phenomena. Different chapters focus on different topics; it mainly includes: Chap 2: comparison between single-shot hydrodynamics event-by-event hydrodynamic simulations. Chap 3: using the elliptic and triangular flow data measured by the ALICE collaboration at the LHC to constrain initial condition models. Chap 4: study on correlations between event-plane angles. Chap 5: how resonance decay calculation can be speed up by a factor of 10. Chap 6: study on fluctuations of event planes angle {\Psi}n(pT) and their theoretical and experimental consequences. Chap 7: sampling particles according to the Cooper-Frye formula.Comment: Zhi Qiu's Ph.D. thesi

The relationship of electron Fermi energy with strong magnetic fields

In order to depict the quantization of Landau levels, we introduce Dirac $\delta$ function, and gain a concise expression for the electron Fermi energy, $E_{F}(e) \propto B^{1/4}$. The high soft X-ray luminosities of magnetars may be naturally explained by our theory.Comment: 3 pages, 1 figure, submitted to OMEG11 Proceeding (Tokyo, Japan. Nov.14-18, 2011
