Corrections to the Hamiltonian induced by finite-strength coupling to the environment
Marcin Åobejko, Marek Winczewski, Gerardo Suárez +2
If a quantum system interacts with the environment, then the Hamiltonian acquires a correction known as the Lamb-shift term. There are two other corrections to the Hamiltonian, rel…

Intermediate Times Dilemma for Open Quantum System: Filtered Approximation to The Refined Weak Coupling Limit
Marek Winczewski, Antonio Mandarino, Gerardo Suarez +2
The famous Davies-GKSL secular Markovian master equation is tremendously successful in approximating the evolution of open quantum systems in terms of just a few parameters. Howeve…
