  • Dynamic control of Purcell enhanced emission of erbium ions in nanoparticles 

    Deshmukh, Chetan; DE RIEDMATTEN, HUGUES (2021-06)
    Article
    Open Access
    The interaction of single quantum emitters with an optical cavity enables the realization of efficient spin-photon interfaces, an essential resource for quantum networks. The dynamical control of the spontaneous emission ...

  • Supersolid-superfluid phase separation in the extended Bose-Hubbard model 

    Kottmann, Korbinian Gebhard; Haller, Andreas; Acín dal Maschio, Antonio; Astrakharchik, Grigori; Lewenstein, Maciej (American Physical Society (APS), 2021-11-01)
    Article
    Open Access
    Recent studies have suggested a new phase in the extended Bose-Hubbard model in one dimension at integer filling. In this work, we show that this new phase is phase-separated into a supersolid and superfluid part, generated ...

  • Selective excitation of individual nanoantennas by pure spectral phase control in the ultrafast coherent regime 

    Accanto, Nicolò; Roque Fernández, Pablo Manuel de; Galvan-Sosa, Marcial; Hancu, Ion Michael; Van Hulst, Niek (2020-09-07)
    Article
    Open Access
    Coherent control is an ingenious tactic to steer a system to a desired optimal state by tailoring the phase of an incident ultrashort laser pulse. A relevant process is the two-photon–induced photoluminescence (TPPL) 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
    Open Access
    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 ...

  • Analysis of intracellular protein dynamics in living zebrafish embryos using light-sheet fluorescence single-molecule microscopy 

    Bernardello, Matteo; Gualda Manzano, Emilio José; Castro Olvera, Gustavo; Loza Álvarez, Pablo (2021-10-01)
    Article
    Open Access
    Single-molecule microscopy techniques have emerged as useful tools to image individual molecules and analyze their dynamics inside cells, but their application has mostly been restricted to cell cultures. Here, a light-sheet ...

  • Light-sheet fluorescence microscopy for the in vivo study of microtubule dynamics in the zebrafish embryo 

    Bernardello, Matteo; Marsal, Maria; Gualda Manzano, Emilio José; Loza Álvarez, Pablo (2021-10-01)
    Article
    Open Access
    During its first hours of development, the zebrafish embryo presents a large microtubule array in the yolk region, essential for its development. Despite of its size and dynamic behavior, this network has been studied only ...

  • Manipulating and measuring single atoms in the Maltese cross geometry 

    Bianchet, Lorena Cecilia; Natalia, Alves; Zarraoa Sardón, Laura; Bruno, Natalia; Mitchell, Morgan W. (2021-09-06)
    Article
    Open Access
    Background: Optical microtraps at the focus of high numerical aperture (high-NA) imaging systems enable efficient collection, trapping, detection and manipulation of individual neutral atoms for quantum technology and ...

  • Autoheterodyne characterization of narrow-band photon pairs 

    Prakash, Vindhiya; Sierant, Aleksandra; Mitchell, Morgan W. (American Institute of Physics (AIP), 2021-07-19)
    Article
    Open Access
    We describe a technique to measure photon pair joint spectra by detecting the time-correlation beat note when nondegenerate photon pairs interfere at a beam splitter. The technique implements a temporal analog of the ...

  • Unidirectional guided resonances in anisotropic waveguides 

    Mukherjee, Samyobrata; Gomis Bresco, Jordi; Artigas García, David; Torner Sabata, Lluís (2021-05-15)
    Article
    Open Access
    We show that anisotropic planar anti-guiding waveguide structures with two radiation channels toward the surrounding cladding materials can support unidirectional guided resonances (UGRs), where radiation is canceled in ...

  • Photocurrent-detected 2D electronic spectroscopy reveals ultrafast hole transfer in operating PM6/Y6 organic solar cells 

    Bolzonello, Luca; Bernal Texca, Francisco Gumaro; Gerling Sarabia, Luis Guillermo; Ockova, Jana; Collini, Elisabetta; Martorell Pena, Jordi; Van Hulst, Niek (2021-04-29)
    Article
    Open Access
    The performance of nonfullerene-acceptor-(NFA)-based organic solar cells is rapidly approaching the efficiency of inorganic cells. The chemical versatility of NFAs extends the light-harvesting range to the infrared, while ...

  • Direct force measurements of subcellular mechanics in confinement using optical tweezers 

    Català Castro, Frederic; Venturini, Valeria; Ruprecht, Verena; Krieg, Michael (2021-08-31)
    Article
    Open Access
    During the development of a multicellular organism, a single fertilized cell divides and gives rise to multiple tissues with diverse functions. Tissue morphogenesis goes in hand with molecular and structural changes at the ...

  • Seven-octave high-brightness and carrier-envelope-phase-stable light source 

    Elu Etxano, Ugaitz; Maidment, Luke; Vamos, Lenard; Badikov, Valeriy; Badikov, Dmitrii; Petrov, Valentin; Biegert, Jens (2021-04)
    Article
    Restricted access - publisher's policy
    High-brightness sources of coherent and few-cycle-duration light waveforms with spectral coverage from the ultraviolet to the terahertz would offer unprecedented versatility and opportunities for a wide range of applications ...
