Quantum collision theory in flat bands
Manuel Valiente, Nikolaj Thomas Zinner
We consider quantum scattering of particles in media exhibiting strong dispersion degeneracy. In particular, we study flat-banded lattices and linearly dispersed energy bands. The…
Spin Localization of a Fermi Polaron in a Quasirandom Optical Lattice
Callum W. Duncan, Niels J. S. Loft, Patrik Öhberg +2
Recently, the topics of many-body localization (MBL) and one-dimensional strongly interacting few-body systems have received a lot of interest. These two topics have been largely d…
Quantum spin transistor with a Heisenberg spin chain
O. V. Marchukov, A. G. Volosniev, M. Valiente +2
We propose and analyze a scheme for conditional state transfer in a Heisenberg spin chain which realizes a quantum spin transistor. In our scheme, the absence or presence of…
Few-Body Route to One-Dimensional Quantum Liquids
Manuel Valiente, Patrik Ohberg
Gapless many-body quantum systems in one spatial dimension are universally described by the Luttinger liquid effective theory at low energies. Essentially, only two parameters ente…
Driven Topological Systems in the Classical Limit
Callum W. Duncan, Patrik Ohberg, Manuel Valiente
Periodically-driven quantum systems can exhibit topologically non-trivial behaviour, even when their quasi-energy bands have zero Chern numbers. Much work has been conducted on non…
Observation of pair tunneling and coherent destruction of tunneling in arrays of optical waveguides
Sebabrata Mukherjee, Manuel Valiente, Nathan Goldman +4
We report on the experimental realization of a photonic system that simulates the one-dimensional two-particle Hubbard model. This analogy is realized by means of two-dimensional a…
