Ultrastrongly coupled open systems and fine grained time
Stefano Marcantoni, Marco Merkli
We study the dynamics of a d-level quantum system coupled to a bosonic reservoir when the coupling constant is large. It is known that in the limit of infinite coupling strength, t…

Ultrastrong coupling, nonselective measurement and quantum Zeno dynamics
Stefano Marcantoni, Marco Merkli
We study the dynamics of an open quantum system linearly coupled to a bosonic reservoir. We show that, in the ultrastrong coupling limit, the system undergoes a nonselective measur…
