Static magnetic susceptibility in finite-density $$SU\left( 2\right) $$ lattice gauge theory

We study static magnetic susceptibility $\chi(T, \mu)$ in $SU(2)$ lattice gauge theory with $N_f = 2$ light flavours of dynamical fermions at finite chemical potential $\mu$. Using linear response we find that exhibits paramagnetic behavior both the high-temperature deconfined regime and low-temperature confining regime. Paramagnetic becomes stronger higher temperatures larger values potential. For our range $0.727 \leq T/T_c 2.67$, first coefficient expansion even powers $\mu/T$ around $\mu=0$ is close to free quarks lies $(2 \ldots 5) \cdot 10^{-3}$. The strongest found diquark condensation phase $\mu > m_{\pi}/2$.
