  • Applying the variational principle to (1+1) dimensional relativistic quantum field theories 
    Haegeman, Jutho; Cirac, J. Ignacio; Osborne, Tobias J.; Verschelde, Henri; Verstraete, Frank (Trieste : International School for Advanced Studies, 2010)
    We extend the recently introduced continuous matrix product state (cMPS) variational class to the setting of (1+1)-dimensional relativistic quantum field theories. This allows one to overcome the difficulties highlighted ...
  • Divergences in QFT on the Noncommutative Minkowski space with Grosse-Wulkenhaar potential 
    Zahn, Jochen (Trieste : International School for Advanced Studies, 2010)
    We study quantum field theory on the two-dimensional Noncommutative Minkoswki space with a Grosse-Wulkenhaar potential. We explicitly construct the retarded propagator and show that it is not a tempered distribution. This ...
  • Generalised fluxes in matrix compactifications 
    Chatzistavrakidis, Athanasios; Jonke, Larisa (Trieste : International School for Advanced Studies, 2012)
    In the recent years a lot of attention is focused on unconventional string compactifications. A variety of different but related frameworks was developed in order to address issues such as duality invariance, non-geometry ...
  • GEO 600: Building a gravitational wave observatory 
    Hewitson, Martin (Trieste : Sissa Medialab Srl, 2005)
    An international network of laser-interferometric gravitational wave detectors is nearing the end of the main commissioning phase and will soon enter into an extended observational period, collecting data for a duration ...
  • LISA and its precursor LISA Pathfinder 
    García Marín, Antonio F.; Heinzel, Gerhard; Danzmann, Karsten (Trieste : Sissa Medialab, 2007)
    The Laser Interferometer Space Antenna (LISA) is a joint ESA-NASA mission designed to observe gravitational waves in the frequency range between 10-4 to 1 Hz, where ground-based detectors are limited by terrestrial noise. ...
  • Listening to the universe with gravitational waves 
    Danzmann, Karsten (Trieste : International School for Advanced Studies, 2009)
    Gravitational waves have been predicted by Albert Einstein more than 90 years ago as a consequence of his theory of general relativity. Several km-size gravitational wave detectors have now gone into operation on the ground ...
  • Noncommutative baby Skyrmions 
    Ioannidou, Theodora; Lechtenfeld, Olaf (Trieste : International School for Advanced Studies, 2010)
    A class of exact analytic noncommutative baby Skyrmions is obtained. The corresponding configurations have singular commutative limit but are stable against scaling due to the noncommutativity. We compute their energies, ...
  • Noncommutative deformation of the Ward metric 
    Goffeng, Magnus; Lechtenfeld, Olaf (Trieste : International School for Advanced Studies, 2011)
    The moduli-space metric in the static non-Abelian charge-two sector of the Moyal-deformed CP1 sigma model in 1+2 dimensions is analyzed. After recalling the commutative results of Ward and Ruback and the ?-regularized ...
  • Noncommutative instantons and solitons 
    Lechtenfeld, Olaf (Trieste : Sissa Medialab Srl, 2003)
    I explain how to construct noncommutative BPS configurations in four and lower dimensions by solving linear matrix equations. Examples are instantons in D=4 Yang-Mills, monopoles in D=3 Yang-Mills-Higgs, and (moving) ...
  • 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. ...
  • String cosmology 
    Zagermann, Marco (Trieste : International School for Advanced Studies, 2009)
    A brief overview of various branches of contemporary string cosmology is given with an emphasis on moduli stabilization, de Sitter vacua, inflation, cosmic strings and primordial gravitational waves.
