  • Manipulation of plasmon electron-hole coupling in quasi-free-standing epitaxial graphene layers 
    Langer, Thomas; Pfnür, Herbert; Tegenkamp, Christoph; Forti, Stiven; Emtsev, Konstantin; Starke, Ulrich (Bristol : IOP Publishing Ltd, 2012-10-29)
    We have investigated the plasmon dispersion in quasi-free-standing monolayer graphene (QFMLG) and epitaxial monolayer graphene (MLG) layers by means of angle resolved electron energy loss spectroscopy. We have shown that ...

    Induced interactions and bound states of charge carriers immersed in a quantum medium are crucial for the investigation of quantum transport. Ultracold atom-ion systems can provide a convenient platform for studying this ...
  • Many-particle mechanics with D(2, 1; alpha) superconformal symmetry 
    Krivonos, Sergey; Lechtenfeld, Olaf (New York, NY : Springer International Publishing, 2011)
    We overcome the barrier of constructing N - 4 superconformal models in one space dimension for more than three particles. The D(2, 1; alpha) superalgebra of our systems is realized on the coordinates and momenta of the ...

    Schmidt, Julian; Hönig, Daniel; Weckesser, Pascal; Thielemann, Fabian; Schaetz, Tobias; Karpa, Leon (Berlin ; Heidelberg : Springer, 2020)
    We study a method for mass-selective removal of ions from a Paul trap by parametric excitation. This can be achieved by applying an oscillating electric quadrupole field at twice the secular frequency ωsec using pairs of ...
  • Massive surface-plasmon polaritons 
    Chichkov, Nikolai B.; Evlyukhin, Andrey B.; Chichkov, Boris N. (Berlin : de Gruyter, 2021)
    It is well-known that a quantum of light (photon) has a zero mass in vacuum. Entering into a medium the photon creates a quasiparticle (polariton, plasmon, surface-phonon, surface-plasmon polariton, etc.) whose rest mass ...
  • MAT-free reflection arrangements 
    Cuntz, Michael; Mücksch, Paul ([Madralin] : EMIS ELibEMS, 2020)
    We introduce the class of MAT-free hyperplane arrangements which is based on the Multiple Addition Theorem by Abe, Barakat, Cuntz, Hoge, and Terao. We also investigate the closely related class of MAT2-free arrangements ...
  • Mathematical modelling and analysis of temperature effects in MEMS 
    Würth, Tim Oliver (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    This thesis is concerned with the mathematical analysis of models for Micro-Electro-Mechanical Systems (MEMS). These models arise in the form of coupled partial differential equations with a moving boundary. Although MEMS ...
  • Mathematical modelling and numerical simulations in physical geodesy 
    Costea, Adrian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2012)

    Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfections, inhomogeneities, and light-absorption ...
  • Matrix model formulation of LS-covariant noncommutative quantum field theories on Minkowski spacetime 
    Fischer, André (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)
    [no abstract]
  • Matrix product states and variational methods applied to critical quantum field theory 
    Milsted, Ashley; Haegeman, Jutho; Osborne, Tobias J. (College Park, MD : American Physical Society, 2013)
    We study the second-order quantum phase transition of massive real scalar field theory with a quartic interaction in (1+1) dimensions on an infinite spatial lattice using matrix product states. We introduce and apply a ...
  • Matter wave interferences of potassium molecules and the influence of collisions with potassium atoms in the ground state 
    Sherstov, Ivan V. (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2006)
    [no abstract]
  • Maximal violation of Bell inequalities by position measurements 
    Kiukas, J.; Werner, R.F. (College Park, MD : American Institute of Physics, 2010)
    We show that it is possible to find maximal violations of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality using only position measurements on a pair of entangled nonrelativistic free particles. The device settings ...
  • Maximizing the capture velocity of molecular magneto-optical traps with Bayesian optimization 
    Xu, Supeng; Kaebert, Paul; Stepanova, Mariia; Poll, Timo; Siercke, Mirco; Ospelkaus, Silke (Bristol, Bad Honnef : IOP Publishing Ltd., Deutsche Physikalische Gesellschaft, 2021-06)
    Magneto-optical trapping (MOT) is a key technique on the route towards ultracold molecular ensembles. However, the realization and optimization of magneto-optical traps with their wide parameter space is particularly ...

    Ubbelohde, Niels; Fricke, Christian; Flindt, Christian; Hohls, Frank; Haug, Rolf J. (Lausanne : Frontiers Research Foundation, 2012-01)
    Electron transport in nanoscale structures is strongly influenced by the Coulomb interaction that gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations of the electrical ...
