Quantum theory of spontaneous emission in multilayer dielectric structures
Celestino Creatore, Lucio Claudio Andreani
We present a fully quantum-electrodynamical formalism suitable to evaluate the spontaneous emission rate and pattern from a dipole embedded in a non-absorbing and lossless multilay…
Unconventional quantum phases of lattice bosonic mixtures
P. Buonsante, S. M. Giampaolo, F. Illuminati +2
We consider strongly interacting boson-boson mixtures on one-dimensional lattices and, by adopting a qualitative mean-field approach, investigate their quantum phases as the inters…
Mixtures of strongly interacting bosons in optical lattices
P. Buonsante, S. M. Giampaolo, F. Illuminati +2
We investigate the properties of strongly interacting heteronuclear boson-boson mixtures loaded in realistic optical lattices, with particular emphasis on the physics of interfaces…
Tkachenko modes in a superfluid Fermi gas at unitarity
Gentaro Watanabe, Marco Cozzini, Sandro Stringari
We calculate the frequencies of the Tkachenko oscillations of a vortex lattice in a harmonically trapped superfluid Fermi gas. We use the elasto-hydrodynamic theory by properly acc…
Many-body interband tunneling as a witness for complex dynamics in the Bose-Hubbard model
Andrea Tomadin, Riccardo Mannella, Sandro Wimberger
A perturbative model is studied for the tunneling of many-particle states from the ground band to the first excited energy band, mimicking Landau-Zener decay for ultracold, spinles…
Ground-State Fidelity and Bipartite Entanglement in the Bose-Hubbard Model
Pierfrancesco Buonsante, Alessandro Vezzani
We analyze the quantum phase transition in the Bose-Hubbard model borrowing two tools from quantum-information theory, i.e. the ground-state fidelity and entanglement measures. We…
