Riccati equation and the problem of decoherence II: Symmetry and the solution of the Riccati equation
Bartlomiej Gardas
In this paper we revisit the problem of decoherence applying the block operator matrices analysis. Riccati algebraic equation associated with the Hamiltonian describing the process…

Exact reduced dynamics for a qubit in a precessing magnetic field and in the contact with a heat-bath
Bartlomiej Gardas
The two-level quantum system (qubit) in a precessing magnetic field and in contact with a heat bath is investigated. The exact reduced dynamics for the qubit in question is obtaine…

Riccati equation and the problem of decoherence
Bartłomiej Gardas
The block operator matrix theory is used to investigate the problem of a single qubit. We will establish a connection between the Riccati operator equation and the possibility of o…
