Аннотация:A possibility of formation of static dual scalar and pseudoscalar density wave condensates in dense
quark matter is considered for the Nambu–Jona-Lasinio model in an external magnetic field. Within a
mean-field approximation, the effective potential of the theory is obtained and its minima are numerically
studied; a phase diagram of the system is constructed. It is shown that the presence of a magnetic field
favors the formation of spatially inhomogeneous condensate configurations at low temperatures and
arbitrary nonzero values of the chemical potential.
