In this paper we study the properties of QCD at nonzero chiral density $$\rho _5$$
ρ
5
, which is introduced through chiral chemical potential $$\mu _5$$
μ
5
. The study is performed within lattice simulation of QCD with dynamical rooted staggered fermions. We first check that $$\rho _5$$
ρ
5
is generated at nonzero $$\mu _5$$
μ
5
and in the chiral limit observe $$\rho _5 \sim \varLambda _{QCD}^2 \mu _5$$

and string tension $$\sigma $$
σ
for various values of $$\mu _5$$

. We observed that string tension grows with $$\mu _5$$

. It seems that topological susceptibility also rises with $$\mu _5$$
μ

, but to state this more reliably the uncertainties should be reduced. We believe that our results indicate possible connection between topological fluctuations and the strength of confinement.
