Direct imaging of topological edge states in cold-atom systems
N. Goldman, J. Dalibard, A. Dauphin +4
Detecting topological order in cold-atom experiments is an ongoing challenge, the resolution of which offers novel perspectives on topological matter. In material systems, unambigu…
Measuring topology in a laser-coupled honeycomb lattice: From Chern insulators to topological semi-metals
N. Goldman, E. Anisimovas, F. Gerbier +3
Ultracold fermions trapped in a honeycomb optical lattice constitute a versatile setup to experimentally realize the Haldane model [Phys. Rev. Lett. 61, 2015 (1988)]. In this syste…
Identifying topological edge states in 2D optical lattices using light scattering
Nathan Goldman, Jerome Beugnon, Fabrice Gerbier
We recently proposed in a Letter [Physical Review Letters 108 255303] a novel scheme to detect topological edge states in an optical lattice, based on a generalization of Bragg spe…
Detecting Chiral Edge States in the Hofstadter Optical Lattice
Nathan Goldman, Jerome Beugnon, Fabrice Gerbier
We propose a realistic scheme to detect topological edge states in an optical lattice subjected to a synthetic magnetic field, based on a generalization of Bragg spectroscopy sensi…
Simulating Z_2 topological insulators with cold atoms in a one-dimensional optical lattice
Feng Mei, Shi-Liang Zhu, Zhi-Ming Zhang +2
We propose an experimental scheme to simulate and detect the properties of time-reversal invariant topological insulators, using cold atoms trapped in one-dimensional bichromatic o…
Coexistence of spin-1/2 and spin-1 Dirac-Weyl fermions in the edge-centered honeycomb lattice
Zhihao Lan, Nathan Goldman, Patrik Ohberg
We investigate the properties of an edge-centered honeycomb lattice, and show that this lattice features both spin-1/2 and spin-1 Dirac-Weyl fermions at different filling fractions…
