Long-range topological insulators and weakened bulk-boundary correspondence
L. Lepori, L. Dell'Anna
We formalize the appearance of new types of insulators in long-range (LR) fermionic systems. These phases are not included in the "ten-fold way classification" (TWC) for the short-…
Dynamics and energy spectra of aperiodic discrete-time quantum walks
C. V. Ambarish, N. Lo Gullo, Th. Busch +2
Deterministically aperiodic sequences are an intermediary between periodic sequences and completely random sequences. Materials which are translationally periodic have Bloch-like e…
Beta-functions of non-linear -models for disordered and interacting electron systems
Luca Dell'Anna
We provide and study complete sets of one-loop renormalization group equations of several Finkel'stein non-linear -models, the effective field theories describing the diffusive…
Self-consistent Keldysh approach to quenches in weakly interacting Bose-Hubbard model
N. Lo Gullo, L. Dell'Anna
We present a non-equilibrium Green's functional approach to study the dynamics following a quench in weakly interacting Bose Hubbard model (BHM). The technique is based on the self…
Violation of Cluster Decomposition and Absence of Light-Cones in Local Integer and Half-Integer Spin Chains
L. Dell'Anna, O. Salberger, L. Barbiero +2
We compute the ground state correlation functions of an exactly solvable chain of integer spins, recently introduced in [R. Movassagh and P. W. Shor, arXiv:1408.1657], whose ground…
Clausius-Mossotti Lorentz-Lorenz relations and retardation effects for two-dimensional crystals
Luca Dell'Anna, Michele Merano
The macroscopic surface electric susceptibility determines the linear optical properties of an insulating single-layer two-dimensional atomic crystal, and can be expressed in terms…
