    • Complex topological soliton with real energy in particle physics 

      Autor: Taira, Takanobu
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      We summarise the procedure used to find the classical masses of Higgs particle, massive gauge boson and t’Hooft-Polyakov monopole in non-Hermitian gauge field theory. Their physical regions are explored, and the mechanism ...

    • Conserved quantities in non-hermitian systems via vectorization method 

      Autor: Agarwal, Kaustubh S.; Muldoon, Jacob; Joglekar, Yogesh N.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      Open classical and quantum systems have attracted great interest in the past two decades. These include systems described by non-Hermitian Hamiltonians with parity-time (PT) symmetry that are best understood as systems ...

    • How to understand the structure of beta functions in six-derivative Quantum Gravity? 

      Autor: Rachwał, Lesław
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      We extensively motivate the studies of higher-derivative gravities, and in particular we emphasize which new quantum features theories with six derivatives in their definitions possess. Next, we discuss the mathematical ...

    • Rational extension of many particle systems 

      Autor: Mandal, Bhabani Prasad
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      In this talk, we briefly review the rational extension of many particle systems, and is based on a couple of our recent works. In the first model, the rational extension of the truncated Calogero-Sutherland (TCS) model is ...

    • Quantum description of angles in the plane 

      Autor: Beneduci, Roberto; Frion, Emmanuel; Gazeau, Jean-Pierre
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The real plane with its set of orientations or angles in [0, π) is the simplest non trivial example of a (projective) Hilbert space and provides nice illustrations of quantum formalism. We present some of them, namely ...

    • Analytic and Algebraic Methods in Physics 

      Autor: Khrabustovskii , Andrii; Znojil , Miloslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
