Anisotropy of magnetized quark matter

Strong transient magnetic fields are generated in noncentral relativistic heavy-ion collisions. These fields induce anisotropy within the strongly interacting medium that, in principle, can affect the thermodynamic properties of the medium. We use the Polyakov loop extended Nambu Jona-Lasinio model to study the quark matter subjected to an external magnetic field at vanishing baryon chemical potential (<a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mrow><a:msub><a:mrow><a:mi mathvariant="italic">μ</a:mi></a:mrow><a:mrow><a:mi mathvariant="italic">B</a:mi></a:mrow></a:msub></a:mrow></a:math>). We have estimated the degree of anisotropy in the speed of sound and isothermal compressibility within the magnetized quark matter as a function of temperature (T) and magnetic field (). This study helps us to understand the extent of directionality generated in the initial stages of noncentral collisions while giving us useful information about the system.
