  • Transverse Hilbert schemes and completely integrable systems 
    Lora, Niccolò; Donin, Lamia (Berlin : Walter de Gruyter, 2017)
    In this paper we consider a special class of completely integrable systems that arise as transverse Hilbert schemes of d points of a complex symplectic surface S projecting onto ℂ via a surjective map p which is a submersion ...
  • Transverse structure and energy deposition by a subTW femtosecond laser in air: from single filament to superfilament

    Kriesell, Matthias (Cambridge : Cambridge University Press, 2005)
    Let G be a noncomplete k -connected graph such that the graphs obtained from contracting any edge in G are not k-connected, and let t(G) denote the number of triangles in G. Thomassen proved t(G) ≥ 1, which was later ...
  • Trickle-down processes and their boundaries 
    Evans, Steven N.; Grübel, Rudolf; Wakolbinger, Anton (Beachwood, OH : Institute of Mathematical Statistics, 2012)
    It is possible to represent each of a number of Markov chains as an evolving sequence of connected subsets of a directed acyclic graph that grow in the following way: initially, all vertices of the graph are unoccupied, ...

  • Trivializable and Quaternionic Subriemannian Structures on S7 and Subelliptic Heat Kernel 
    Bauer, Wolfram; Laaroussi, Abdellah (New York, NY : Springer, 2022)
    On the seven dimensional Euclidean sphere S7 we compare two subriemannian structures with regards to various geometric and analytical properties. The first structure is called trivializable and the underlying distribution ...
  • Truncation identities for the small polaron fusion hierarchy 
    Grabinski, Andre M.; Frahm, Holger (Bristol : IOP Publishing Ltd., 2013-04-17)
    We study a one-dimensional lattice model of interacting spinless fermions. This model is integrable for both periodic and open boundary conditions; the latter case includes the presence of Grassmann valued non-diagonal ...

    We present the production of dual-species Bose-Einstein condensates (BECs) of 39K and 87Rb. Preparation of both species in the |F=1,mF=−1⟩ state enabled us to exploit a total of three Feshbach resonances, which allows for ...
