Haldane phase in the sawtooth lattice: Edge states, entanglement spectrum and the flat band
Benoît Grémaud, G. George Batrouni
Using density matrix renormalization group numerical calculations, we study the phase diagram of the half filled Bose-Hubbard system in the sawtooth lattice with strong frustration…
Two-dimensional network of atomtronic qubits
Shabnam Safaei, Benoît Grémaud, Rainer Dumke +3
Through a combination of laser beams, we engineer a two-dimensional optical lattice of Mexican hat potentials able to host atoms in its ring-shaped wells. When tunneling can be ign…
Ultrametric spaces of branches on arborescent singularities
Evelia R. García Barroso, Pedro D. González Pérez, Patrick Popescu-Pampu
Let be a normal complex analytic surface singularity. We say that is arborescent if the dual graph of any resolution of it is a tree. Whenever are distinct branches o…
