On the standard quantum Brownian equation and an associated class of non-autonomous master equations
Allan Tameshtit
It is shown that the standard quantum Brownian equation (QBE) can violate positivity not only past the thermal correlation time, but at arbitrarily long times at high system freque…

Zero-point energies, the uncertainty principle and positivity of the quantum Brownian density operator
Allan Tameshtit
High temperature and white noise approximations are frequently invoked when deriving the quantum Brownian equation for an oscillator. Even if this white noise approximation is avoi…
