Resonance phenomena in asymmetric superconducting quantum interference devices
T. P. Polak, E. Sarnelli
Theory of self induced resonances in asymmetric two-junction interferometer device is presented. In real devices it is impossible to have an ideal interferometer free of imperfecti…

Quantum rotor description of the Mott-insulator transition in the Bose-Hubbard model
T. P. Polak, T. K. Kopeć
We present the novel approach to the Bose-Hubbard model using the quantum rotor description. The effective action formalism allows us to formulate a problem in the…

Competition between local and nonlocal dissipation effects in two-dimensional quantum Josephson junction arrays
T. P. Polak, T. K. Kopec
We discuss the local and nonlocal dissipation effects on the existence of the global phase coherence transitions in two dimensional Josephson-coupled junctions. The quantum phase t…
