Abstract:Effects of an external magnetic field on the fluctuations of quark number, fluctuations, and correlations of conserved charges, including baryon number, electric charge, and strangeness, are studied in the 2+1 flavor Polyakov-Nambu-Jona-Lasinio model. We find that a magnetic field increases fluctuations and correlations in the regime of chiral crossover. It makes the transition of quadratic fluctuations more abrupt, and the peak structure of quartic fluctuations more pronounced. Our calculations indicate that χB4/χB2, χQ4/χQ2, and χBQ11 are very sensitive to the external magnetic field and can
