Singular dynamics and emergence of nonlocality in long-range quantum models
L. Lepori, A. Trombettoni, D. Vodola
We discuss how nonlocality originates in long-range quantum systems and how it affects their dynamics at and out of the equilibrium. We focus in particular on the Kitaev chains wit…
Effective Theory and Breakdown of Conformal Symmetry in a Long-Range Quantum Chain
Luca Lepori, Davide Vodola, Guido Pupillo +2
We deal with the problem of studying the effective theories and the symmetries of long-range models around critical points. We focus in particular on the Kitaev chain with long-ran…
Long-range Ising and Kitaev Models: Phases, Correlations and Edge Modes
Davide Vodola, Luca Lepori, Elisa Ercolessi +1
We analyze the quantum phases, correlation functions and edge modes for a class of spin-1/2 and fermionic models related to the 1D Ising chain in the presence of a transverse field…
Kitaev chains with long-range pairing
Davide Vodola, Luca Lepori, Elisa Ercolessi +2
We propose and analyze a generalization of the Kitaev chain for fermions with long-range -wave pairing, which decays with distance as a power-law with exponent . Using the in…
