Winding number order in the Haldane model with interactions
Emilio Alba, Jiannis Pachos, Juan Jose Garcia-Ripoll
We study the Haldane model with nearest-neighbor interactions. This model is physically motivated by the associated ultracold atoms implementation. We show that the topological pha…
Detection of Chern numbers and entanglement in topological two-species systems through subsystem winding numbers
James de Lisle, Suvabrata De, Emilio Alba +4
Topological invariants, such as the Chern number, characterise topological phases of matter. Here we provide a method to detect Chern numbers in systems with two distinct species o…
Topological phase transitions driven by non-Abelian gauge potentials in optical square lattices
M. Burrello, I. C. Fulga, E. Alba +2
We analyze a tight-binding model of ultracold fermions loaded in an optical square lattice and subjected to a synthetic non-Abelian gauge potential featuring both a magnetic field…
Hall response of interacting bosonic atoms in strong gauge fields: from condensed to FQH states
H. Pino, E. Alba, J. Taron +2
Interacting bosonic atoms under strong gauge fields undergo a series of phase transitions that take the cloud from a simple Bose-Einstein condensate all the way to a family of frac…
Seeing Majorana fermions in time-of-flight images of spinless fermions coupled by s-wave pairing
Jiannis K. Pachos, Emilio Alba, Ville Lahtinen +1
The Chern number, nu, as a topological invariant that identifies the winding of the ground state in the particle-hole space, is a definitive theoretical signature that determines w…
Generating and verifying graph states for fault-tolerant topological measurement-based quantum computing in 2D optical lattices
Jaewoo Joo, Emilio Alba, Juan José García-Ripoll +1
We propose two schemes for implementing graph states useful for fault-tolerant topological measurement-based quantum computation in 2D optical lattices. We show that bilayer cluste…
