    • Absence of off-diagonal long-range order in hcp 4He dislocation cores 

      de Koning, Maurice; Cai, Wei; Cazorla Silva, Claudio; Boronat Medico, Jordi (American Institute of Physics (AIP), 2023-01-03)
      Article
      Accés obert
      The mass transport properties along dislocation cores in hcp 4 He are revisited by considering two types of edge dislocations as well as a screw dislocation, using a fully correlated quantum simulation approach. Specifically, ...

    • Bounds on the capacity and power of quantum batteries 

      Julià Farré, Sergi; Salamon, Tymoteusz Piotr; Riera Graells, Arnau; Bera, Manabendra Nath; Lewenstein, Maciej (American Physical Society, 2020-05-01)
      Article
      Accés obert
      Quantum batteries, composed of quantum cells, are expected to outperform their classical analogs. The origin of such advantages lies in the role of quantum correlations, which may arise during the charging and ...

    • Darboux integrals for Schrödinger planar vector fields via Darboux transformations 

      Acosta Humánez, Primitivo Belén; Pantazi, Chara (2011-11-01)
      Report de recerca
      Accés obert
      In this paper we study the Darboux transformations of planar vector fields of Schrödinger type. Using the isogaloisian property of Darboux transformation we prove the “invariance” of the elements of the “Darboux Theory of ...

    • Equivalence regimes for geometric quantum discord and local quantum uncertainty 

      Cordero Salvador, Oscar; Villegas Juárez, Arturo; Álvarez, Juan Rafael; De León Montiel, Roberto de J.; Passos, Marcello H. M.; Torres, Juan P. (American Physical Society, 2021-10-01)
      Article
      Accés obert
      The concept of quantum discord aims at unveiling quantum correlations that go beyond those described by entanglement. Its original formulation [L. Henderson and V. Vedral, J. Phys. A: Math. Gen. 34, 6899 (2001); H. Ollivier ...

    • Quantum error-correcting codes and their geometries 

      Ball, Simeon Michael; Centelles Tarrés, Aina; Huber, Felix (European Mathematical Society (EMS), 2023-02-10)
      Article
      Accés obert
      This is an expository article aiming to introduce the reader to the underlying mathematics and geometry of quantum error correction. Information stored on quantum particles is subject to noise and interference from the ...

    • Self-Trapped polarons and topological defects in a topological mott insulator 

      Julià Farré, Sergi; Müller, Markus; Lewenstein, Maciej; Dauphin, Alexandre (American Institute of Physics (AIP), 2020-12-11)
      Article
      Accés obert
      Many-body interactions in topological quantum systems can give rise to new phases of matter, which simultaneously exhibit both rich spatial features and topological properties. In this work, we consider spinless fermions ...

    • Ultra-long quantum walks via spin–orbit photonics 

      Di Colandrea, Francesco; Babazadeh, Amin; Dauphin, Alexandre; Massignan, Pietro Alberto; Marrucci, Lorenzo; Cardano, Filippo (Optical Society of American (OSA), 2023-03-01)
      Article
      Accés obert
      The possibility of fine-tuning the couplings between optical modes is a key requirement in pho- tonic circuits for quantum simulations. In these architectures, emulating the long-time evolution of particles across large ...
