  • Setting a disordered password on a photonic memory 

    Su, Shih-Wei; Gou, Shih-Chuan; Chew, Lock Yue; Chang, Yu-Yen; Yu, Ite A.; Kalachev, Alexey; Liao, Wen-Te (2017)
    An all-optical method of setting a disordered password on different schemes of photonic memory is theoretically studied. While photons are regarded as ideal information carriers, it is imperative to implement such data ...
  • Multiscale approach to nematic liquid crystals via statistical field theory 

    Lu, Bing-Sui (2017)
    We propose an approach to a multiscale problem in the theory of thermotropic uniaxial nematics based on the method of statistical field theory. This approach enables us to relate the coefficients A, B, C, L1, and L2 of the ...
  • Force percolation transition of jammed granular systems 

    Pathak, Sudhir Narayan; Esposito, Valentina; Coniglio, Antonio; Ciamarra, Massimo Pica (2017)
    The mechanical and transport properties of jammed materials originate from an underlying percolating network of contact forces between the grains. Using extensive simulations we investigate the force-percolation transition ...
  • Shock propagation in locally driven granular systems 

    Joy, Jilmy P.; Pathak, Sudhir Narayan; Das, Dibyendu; Rajesh, R. (2017)
    We study shock propagation in a system of initially stationary hard spheres that is driven by a continuous injection of particles at the origin. The disturbance created by the injection of energy spreads radially outward ...
  • Pseudo-Hermitian Hamiltonians generating waveguide mode evolution 

    Chen, Penghua; Chong, Yi Dong (2017)
    We study the properties of Hamiltonians defined as the generators of transfer matrices in quasi-one-dimensional waveguides. For single- or multimode waveguides obeying flux conservation and time-reversal invariance, the ...
  • Genuine N-partite entanglement without N-partite correlation functions 

    Tran, Minh Cong; Zuppardo, Margherita; de Rosier, Anna; Knips, Lukas; Laskowski, Wiesław; Paterek, Tomasz; Weinfurter, Harald (2017)
    A genuinely N-partite entangled state may display vanishing N-partite correlations measured for arbitrary local observables. In such states the genuine entanglement is noticeable solely in correlations between subsets of ...
  • Device-independent characterizations of a shared quantum state independent of any Bell inequalities 

    Wei, Zhaohui; Sikora, Jamie (2017)
    In a Bell experiment two parties share a quantum state and perform local measurements on their subsystems separately, and the statistics of the measurement outcomes are recorded as a Bell correlation. For any Bell correlation, ...
  • Past of a quantum particle revisited 

    Englert, Berthold-Georg; Horia, Kelvin; Dai, Jibo; Len, Yink Loong; Ng, Hui Khoon (2017)
    We analyze Vaidman's three-path interferometer with weak path marking [L. Vaidman, Phys. Rev. A 87, 052104 (2013)] and find that common sense yields correct statements about the particle's path through the interferometer. ...
  • Nodal Brillouin-zone boundary from folding a Chern insulator 

    Lang, Li-Jun; Zhang, Shao-Liang; Zhou, Qi (2017)
    A Chern insulator is a building block of many topological quantum matters. Here, we discuss a nonsymmorphic Chern insulator, which preserves the nonsymmorphic symmetry and breaks the time-reversal symmetry. It consists of ...

    Luk'yanchuk, Boris; Paniagua-Domínguez, Ramón; Kuznetsov, Arseniy I.; Miroshnichenko, Andrey E.; Kivshar, Yuri S. (2017)
    We investigate the peculiarities of light scattering from subwavelength particles made of high-refractive-index materials caused by the coexistence of particular anapole modes of both electric and magnetic character. The ...
