Quantum transport equations for Bose systems taking into account
... The problems of building a kinetic equation for Bose systems based on the microscopic approach were considered by Akhiezer and Peletminsky [21] and by Kirkpatrick and Dorfman [22–24]. The results of [22, 23] were extended and used to describe the trapped weakly-interacting Bose gases at finite temper ...

However, it should be stressed that, even though some regions have negative energy density, the total energy of the system is always nonnegative. Hence, there exist no states with energy lower than the ground st ...
