Experimental observation of Aharonov-Bohm caging using orbital angular momentum modes in optical waveguides
C. Jörg, G. Queraltó, M. Kremer +6
The discovery of artificial gauge fields, controlling the dynamics of uncharged particles that otherwise elude the influence of standard electric or magnetic fields, has revolution…
Second-order topological corner states with ultracold atoms carrying orbital angular momentum in optical lattices
G. Pelegrí, A. M. Marques, V. Ahufinger +2
We propose a realization of a two-dimensional higher-order topological insulator with ultracold atoms loaded into orbital angular momentum (OAM) states of an optical lattice. The s…
Quantum magnetism with ultracold bosons carrying orbital angular momentum
G. Pelegrí, J. Mompart, V. Ahufinger +1
We show how strongly correlated ultracold bosonic atoms loaded in specific orbital angular momentum states of arrays of cylindrically symmetric potentials can realize a variety of…
Quantum sensing using imbalanced counter-rotating Bose--Einstein condensate modes
G. Pelegrí, J. Mompart, V. Ahufinger
A quantum device for measuring two-body interactions, scalar magnetic fields and rotations is proposed using a Bose--Einstein condensate (BEC) in a ring trap. We consider an imbala…
Topological edge states and Aharanov-Bohm caging with ultracold atoms carrying orbital angular momentum
G. Pelegrí, A. M. Marques, R. G. Dias +3
We show that bosonic atoms loaded into orbital angular momentum states of a lattice in a diamond-chain geometry provides a flexible and simple platform for exploring a range…
Topological edge states with ultracold atoms carrying orbital angular momentum in a diamond chain
G. Pelegrí, A. M. Marques, R. G. Dias +3
We study the single-particle properties of a system formed by ultracold atoms loaded into the manifold of Orbital Angular Momentum (OAM) states of an optical lattice with a d…
Single atom edge-like states via quantum interference
G. Pelegrí, J. Polo, A. Turpin +3
We demonstrate how quantum interference may lead to the appearance of robust edge-like states of a single ultracold atom in a two-dimensional optical ribbon. We show that these sta…
