Non-Hermitian transparency and one-way transport in low-dimensional lattices by an imaginary gauge field
Stefano Longhi, Davide Gatti, Giuseppe Della Valle
Unidirectional and robust transport is generally observed at the edge of two- or three-dimensional quantum Hall and topological insulator systems. A hallmark of these systems is to…
Plasmonics in heavily-doped semiconductor nanocrystals
Francesco Scotognella, Giuseppe Della Valle, Ajay Ram Srimath Kandada +6
Heavily-doped semiconductor nanocrystals characterized by a tunable plasmonic band have been gaining increasing attention recently. Herein, we introduce this type of materials focu…
Klein tunneling of two correlated bosons
S. Longhi, G. Della Valle
Reflection of two strongly interacting bosons with long-rage interaction hopping on a one-dimensional lattice scattered off by a potential step is theoretically investigated in the…
Observation of surface states with algebraic localization
G. Corrielli, G. Della Valle, A. Crespi +2
We introduce and experimentally demonstrate a class of surface bound states with algebraic decay in a one-dimensional tight-binding lattice. Such states have an energy embedded in…
