  • Nontrivial optical response of silicon triangular prisms 
    Poleva, M.; Baryshnikova, K.V.; Frizyuk, K.; Evlyukhin, A.B. (Bristol : IOP Publ., 2021)
    The electromagnetic response of silicon triangle nanoprisms in the near-infrared region is investigated. It is revealed that the bianisotropic dipole approximation is insufficient for this geometry since the direct application ...
  • A note on Lagrangian submanifolds in symplectic 4m-manifolds 
    Zhang, Yuguang (Cambridge : Cambridge University Press, 2022)
    This short paper shows a topological obstruction of the existence of certain Lagrangian submanifolds in symplectic 4m -manifolds.
  • Novel approach to observing system simulation experiments improves information gain of surface-atmosphere field measurements 
    Metzger, Stefan; Durden, David; Paleri, Sreenath; Sühring, Matthias; Butterworth, Brian J.; Florian, Christopher; Mauder, Matthias; Plummer, David M.; Wanner, Luise; Xu, Ke; Desai, Ankur R. (Katlenburg-Lindau : Copernicus, 2021)
    The observing system design of multidisciplinary field measurements involves a variety of considerations on logistics, safety, and science objectives. Typically, this is done based on investigator intuition and designs of ...
  • Novel approaches to topological order involving open boundaries in closed and open quantum systems 
    Gangapuram, Amit Jamadagni (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    The fundamental understanding of phases and their transitions has been a central theme in condensed matter physics. Until recently, it was largely believed that the Landau symmetry breaking principle was effective in ...
  • Novel Ringdown Amplitude-Phase Consistency Test 
    Forteza, Xisco Jiménez; Bhagwat, Swetha; Kumar, Sumit; Pani, Paolo (College Park, Md. : APS, 2023)
    The ringdown signal emitted during a binary black hole coalescence can be modeled as a linear superposition of the characteristic damped modes of the remnant black hole that get excited during the merger phase. While ...
  • Novel scenarios of ultracold lattice gases 
    Greschner, Sebastian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2016)
    [no abstract]
  • A novel, robust quantum detection scheme 
    Hemmerling, Boerge; Gebert, Florian; Wan, Yong; Schmidt, Piet O. (Bristol : IOP Publishing Ltd., 2012)
    Protocols used in quantum information and precision spectroscopy rely on efficient internal quantum state discrimination. With a single ion in a linear Paul trap, we implement a novel detection method which utilizes ...
  • Nuclear ranges in implicative semilattices 
    Erné, Marcel (Basel : Springer, 2022)
    A nucleus on a meet-semilattice A is a closure operation that preserves binary meets. The nuclei form a semilattice N A that is isomorphic to the system NA of all nuclear ranges, ordered by dual inclusion. The nuclear ...
  • Nucleon-deuteron scattering with Δ-isobar excitation: Perturbation theory 
    Deltuva, A.; Chmielewski, K.; Sauer, P.U. (College Park, MD : American Physical Society, 2003)
    A perturbative approach for the description of elastic and inelastic nucleon-deuteron scattering is developed. Its validity is discussed. The aim of the perturbative approach is the isolation of details of different reaction ...
  • Null vectors in logarithmic conformal field theory 
    Flohr, Michael (Trieste : Sissa Medialab Srl, 2000)
    The representation theory of the Virasoro algebra in the case of a logarithmic conformal field theory is considered. Here, indecomposable representations have to be taken into account, which has many interesting consequences. ...
  • Number-phase uncertainty relations and bipartite entanglement detection in spin ensembles 
    Vitagliano, Giuseppe; Fadel, Matteo; Apellaniz, Iagoba; Kleinmann, Matthias; Lücke, Bernd; Klempt, Carsten; Tóth, Géza (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2023)
    We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays the role of a number-phase uncertainty for ...
  • Number-resolved Analysis of Many-body Quantum States 
    Hetzel, Mareike (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    Quantum sensors have emerged as a revolutionary technology that harnesses quantum phenomena to surpass the resolution of classical sensors. By leveraging the unique property of quantum particles to exist in superposition ...
  • Number-resolved preparation of mesoscopic atomic ensembles 
    Hüper, Andreas; Pür, Cebrail; Hetzel, Mareike; Geng, Jiao; Peise, Jan; Kruse, Ilka; Althoff Kristensen, Mick; Ertmer, Wolfgang; Arlt, Jan J.; Klempt, Carsten (London : IOP, 2021)
    The analysis of entangled atomic ensembles and their application for interferometry beyond the standard quantum limit requires an accurate determination of the number of atoms. We present an accurate fluorescence detection ...
  • Numerical analysis of LG3,3 second harmonic generation in comparison to the LG0,0 case 
    Heinze, Joscha; Vahlbruch, Henning; Willke, Benno (Washington, DC : OSA - The Optical Society, 2020)
    For coating Brownian thermal noise reduction in future gravitational wave detectors, it is proposed to use light in the helical Laguerre-Gaussian LG3,3 mode instead of the currently used LG0,0 mode. However, the simultaneous ...
  • Numerical analysis of the ultra-wide tunability of nanofiber Bragg cavities 
    Takashima, Hideaki; Schell, Andreas W.; Takeuchi, Shigeki (Washington, DC : Optica, 2023)
    Nanofiber Bragg cavities (NFBCs) are solid-state microcavities fabricated in optical tapered fiber. They can be tuned to a resonance wavelength of more than 20 nm by applying mechanical tension. This property is important ...
