Local density fluctuation near the QCD critical point has been suggested to exhibit a power-law behavior which can be probed by an intermittency analysis on scaled factorial moment in relativistic heavy-ion collisions. In this talk, I will review recent work on the search for power-law fluctuations with fractality and intermittency analysis in heavy-ion collisions. Experimental measurement...

strong magnetic fields are created at the early stage of non-central heavy-ion collisions. However, whether the magnetic fields survive in the late stage of heavy-ion collisions and experimental measurements of various observables are reminiscent of the initially-created magnetic fields still remains elusive. In this talk we show that fluctuations of and correlations among net baryon number,...

Jet quenching parameter $\hat{q}$ is an essential parameter that characterizes the interaction strength between jet partons and the QGP. Based on the quark-meson model, we conduct a first calculation on $\hat{q}$ at finite chemical potential up to the one-loop order, and find that the momentum broadening of jets is enhanced not only at high temperature, but also at high chemical potential. We...

To account for the acceptance effect of two-particle correlations, a normalization is performed in pioneer work. We propose a normalization scheme based on an independent particle assumption to improve the background estimation. Choosing per-trigger yield calculated by CGC as an example, a comparison of the background proposed in this paper with that in pioneer work is made. The differences...
