  1. 66. The Schwinger model in the canonical formulation
    Prof. Urs Wenger (University of Bern)
    26/06/2019, 16:20
    Oral talk
    We consider the massive Schwinger model in the canonical formulation using transfer matrices in fixed fermion number sectors. The fermion contributions can be classified according to the discrete, local fermion occupation numbers which define specific fermion states. They can be used to expose the vacuum structure of the theory and the origin of the sign problem at finite fermion number...

  2. 33. Tensor network study of two dimensional complex $\phi^{4}$ theory at finite density
    Dr Ryo Sakai (Kanazawa University)
    26/06/2019, 16:45
    Oral talk
    We study the complex $\phi^{4}$ theory with finite chemical potential. To closely understand nontrivial effects such as the Silver Blaze phenomenon, experimental studies on the lattice will give some knowledge; however, on account of the finite chemical potential, there is a sign problem in Monte Carlo simulations. In this study, to overcome the problem, the tensor renormalization group...

  3. 54. Schwinger-Keldysh formalism for Lattice Gauge Theories
    Mr Hiroki Hoshina (The Univ. of Tokyo, Komaba)
    26/06/2019, 17:10
    Oral talk
    It is important to compute transport coefficients in QCD at finite temperature and density. When the imaginary-time formalism of Lattice QCD is used, the spectral functions have to be reconstructed by supplementing certain Ansatze for correlation functions on the lattice. On the other hand, real-time Green's functions can be obtained directly in the Schwinger-Keldysh (SK) formalism. But the SK...
