9 p, 843.4 KB Engineering of orbital angular momentum supermodes in coupled optical waveguides / Turpin Avilés, Alejandro (Universitat Autònoma de Barcelona. Departament de Física) ; Pelegrí Andres, Gerard (Universitat Autònoma de Barcelona. Departament de Física) ; Polo Gomez, Juan (Universitat Autònoma de Barcelona. Departament de Física) ; Mompart Penina, Jordi (Universitat Autònoma de Barcelona. Departament de Física) ; Ahufinger, Verònica (Universitat Autònoma de Barcelona. Departament de Física)
In this work we demonstrate the existence of orbital angular momentum (OAM) bright and dark supermodes in a three-evanescently coupled cylindrical waveguides system. Bright and dark supermodes are characterized by their coupling and decoupling from one of the waveguides, respectively. [...]

We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical crystals. For a beam focused to a plane behind the crystal, the focal plane exhibits two concentric bright rings enclosing a ring of null intensity called the Poggendorff ring. [...]

11 p, 2.2 MB Transport of ultracold atoms between concentric traps via spatial adiabatic passage / Polo Gomez, Juan (Universitat Autònoma de Barcelona. Departament de Física) ; Benseny Cases, Albert (Okinawa Institute of Science and Technology. Quantum Systems Unit) ; Busch, Thomas (Okinawa Institute of Science and Technology. Quantum Systems Unit) ; Ahufinger, Verònica (Universitat Autònoma de Barcelona. Departament de Física) ; Mompart Penina, Jordi (Universitat Autònoma de Barcelona. Departament de Física)
Spatial adiabatic passage processes for ultracold atoms trapped in tunnel-coupled cylindrically symmetric concentric potentials are investigated. Specifically, we discuss the matter-wave analog of the rapid adiabatic passage (RAP) technique for a high fidelity and robust loading of a single atom into a harmonic ring potential from a harmonic trap, and for its transport between two concentric rings.

145 p, 3.2 MB Tunneling dynamics of ultracold atoms / Polo Gomez, Juan, autor ; Ahufinger, Verònica, supervisor acadèmic (Universitat Autònoma de Barcelona. Departament de Física) ; Universitat Autònoma de Barcelona. Departament de Física
La teoria que descriu la Mecànica Quàntica ens ha permès el descobriment de molts fenòmens que prèviament eren ocults dins la seva naturalesa probabilística. Concretament, la Mecànica Quàntica va permetre veure l'ara anomenada dualitat ona-partícula en objectes extremadament petits. [...]
The theory of Quantum Mechanics led to the discovery of many phenomena that were previously hidden by its probabilistic nature. In particular, Quantum Mechanics brought to light the so-called wave-particle duality behavior of extremely small objects. [...]
