Knotting fractional-order knots with the polarization state of light
Pisanty, Emilio; Machado, Gerard J.; Vicuña-Hernández, Verónica; Picón, Antonio; Celi, Alessio; Pérez Torres, Juan; Lewenstein, Maciej (Nature, 2019-06-10)
Article
Accés obertThe fundamental polarization singularities of monochromatic light are normally associated with invariance under coordinated rotations: symmetry operations that rotate the spatial dependence of an electromagnetic field by ... -

Measuring Chern numbers in Hofstadter strips
Mugel, Samuel; Dauphin, Alexandre; Massignan, Pietro Alberto; Tarruell, Leticia; Lewenstein, Maciej; Lobo, Carlos; Celi, Alessio (2017-08-15)
Article
Accés obertTopologically non-trivial Hamiltonians with periodic boundary conditions are characterized by strictly quantized invariants. Open questions and fundamental challenges concern their existence, and the possibility of measuring ... -
Quantum simulation of non-trivial topology
Boada, Octavi; Celi, Alessio; Rodríguez-Laguna, Javier; Latorre, José I.; Lewenstein, Maciej (IOP, 2015-04-15)
Article
Accés obertWe propose several designs to simulate quantum many-body systems in manifolds with a non-trivial topology. The key idea is to create a synthetic lattice combining real-space and internal degrees of freedom via a suitable ... -
Synthetic magnetic fluxes and topological order in one-dimensional spin systems
Graß, Tobias; Muschik, Christine; Celi, Alessio; Chhajlany, Ravindra W.; Lewenstein, Maciej (APS Physics, 2015-06-11)
Article
Accés obertEngineering topological quantum order has become a major field of physics. Many advances have been made by synthesizing gauge fields in cold atomic systems. Here we carry over these developments to other platforms which ... -
Tensor Networks for Lattice Gauge Theories with continuous groups
Tagliacozzo, Luca; Celi, Alessio; Lewenstein, Maciej (ACS Publications, 2014-11-06)
Article
Accés obertWe discuss how to formulate lattice gauge theories in the tensor-network language. In this way, we obtain both a consistent-truncation scheme of the Kogut-Susskind lattice gauge theories and a tensornetwork variational ...
