  • Magnetic properties and quench dynamics of two interacting ultracold molecules in a trap 

    Dawid Lekowska, Anna Maria; Tomza, Michal (Royal Society of Chemistry (RSC), 2020)
    Article
    Open Access
    We theoretically investigate the magnetic properties and nonequilibrium dynamics of two interacting ultracold polar and paramagnetic molecules in a one-dimensional harmonic trap in external electric and magnetic fields. ...

  • Quantum channel marginal problem 

    Hsieh, Chung Yun; Lostaglio, Matteo; Acín dal Maschio, Antonio (American Physical Society, 2022-03-31)
    Article
    Open Access
    Given a set of local dynamics, are they compatible with a global dynamics? We systematically formulate these questions as quantum channel marginal problems. These problems are strongly connected to the generalization of ...

  • Entanglement preserving local thermalization 

    Hsieh, Chung Yun; Lostaglio, Matteo; Acín dal Maschio, Antonio (American Physical Society, 2020-03-30)
    Article
    Open Access
    We investigate whether entanglement can survive the thermalization of subsystems. We present two equivalent formulations of this problem: (1) Can two isolated agents, accessing only preshared randomness, locally thermalize ...

  • Communication, dynamical resource theory, and thermodynamics 

    Hsieh, Chung Yun (2021-05-12)
    Article
    Open Access
    Recently, new insights have been obtained by jointly studying communication and resource theory. This interplay consequently serves as a potential platform for interdisciplinary studies. To continue this line, we analyze ...

  • Resource preservability 

    Hsieh, Chung Yun (2020-03-19)
    Article
    Open Access
    Resource theory is a general, model-independent approach aiming to understand the qualitative notion of resource quantitatively. In a given resource theory, free operations are physical processes that do not create the ...

  • Single-domain Bose condensate magnetometer achieves energy resolution per bandwidth below h 

    Coop, Simon; Palacios, Silvana; Gómez Kabelka, Pau; Zamora Zamora, Roberto; Mazzinghi, Chiara; Mitchell, Morgan W. (2022-02-08)
    Article
    Open Access
    We present a magnetic sensor with energy resolution per bandwidth ER < h. We show how a 87Rb single-domain spinor Bose– Einstein condensate, detected by nondestructive Faraday rotation probing, achieves single-shot ...

    Mazzinghi, Chiara; Gómez Kabelka, Pau; Martin, Ferran; Coop, Simon; Palacios, Silvana; Mitchell, Morgan W. (American Physical Society (APS), 2019-09-10)
    Article
    Open Access
    We present interferometeric measurements of the f = 1 to f = 2 interhyperfine scattering lengths in a single-domain spinor Bose-Einstein condensate of 87Rb. The interhyperfine interaction leads to a strong and state-dependent ...

  • Cavity-enhanced polarization rotation measurements for low-disturbance probing of atoms 

    Mazzinghi, Chiara; Benedicto Orenes, Daniel; Gómez Kabelka, Pau; Lucivero, Vito Giovanni; Aybar, Enes; Gugnani, Stuti; Mitchell, Morgan W. (2021-12-06)
    Article
    Open Access
    We propose and demonstrate cavity-enhanced polarization-rotation measurement as a means to detect magnetic effects in transparent media with greater sensitivity at equal optical disturbance to the medium. Using the Jones ...

  • Bose-Einstein condensate comagnetometer 

    Mazzinghi, Chiara; Gómez Kabelka, Pau; Martin, Ferran; Benedicto Orenes, Daniel; Palacios, Silvana; Mitchell, Morgan W. (American Institute of Physics (AIP), 2020-04-29)
    Article
    Open Access
    We describe a comagnetometer employing the f ¼ 1 and f ¼ 2 ground state hyperfine manifolds of a 87Rb spinor Bose-Einstein condensate as colocated magnetometers. The hyperfine manifolds feature nearly opposite gyromagnetic ...

  • Scalable and tunable periodic graphene nanohole arrays for mid-infrared plasmonics 

    Gopalan, Kavitha K.; Paulillo, Bruno; Mackenzie, David M. A.; Rodrigo, Daniel; Bareza, Néstor; Whelan, Patrick R.; Shivayogimath, Abhay; Pruneri, Valerio (2018-09-12)
    Article
    Open Access
    Despite its great potential for a wide variety of devices, especially mid-infrared biosensors and photodetectors, graphene plasmonics is still confined to academic research. A major reason is the fact that, so far, ...

  • Controlling mid-infrared plasmons in graphene nanostructures through post-fabrication chemical doping 

    Paulillo, Bruno; Bareza, Néstor; Pruneri, Valerio (2021-07-01)
    Article
    Open Access
    Engineering the doping level in graphene nanostructures to yield controlled and intense localized surface plasmon resonance (LSPR) is fundamental for their practical use in applications such as molecular sensing for point ...

  • Mid-infrared gas sensing using graphene plasmons tuned by reversible chemical doping 

    Bareza, Néstor; Gopalan, Kavitha K.; Alani, Rose; Paulillo, Bruno; Pruneri, Valerio (2020-04-15)
    Article
    Open Access
    Highly confined plasmon modes in nanostructured graphene can be used to detect tiny quantities of biological and gas molecules. In biosensing, a specific biomarker can be concentrated close to graphene, where the optical ...
