      In this paper, we analyze the activation of the violation of the Svetlichny inequality in GHZ states in the presence of noise. We take into account bit flip, phase flip, amplitude damping and depolarizing noisy channels ...
    • On the triviality of higher-derivative theories 

      Andrzejewski, Krzysztof; Gonera, Joanna ORCID; Machalski, Piotr; Bolonek-Lasoń, Katarzyna ORCID (North-Holland, 2012)
      The higher-derivative theories with degenerate frequencies exhibit BRST symmetry [V.O. Rivelles, Phys. Lett. B 577 (2003) 147]. In the present Letter meaning of BRST-invariance condition is analyzed. The BRST symmetry is ...
    • Perturbative quantum damping of cosmological expansion 

      Broda, Bogusław (North-Holland, 2014)
      Perturbative quantum gravity in the framework of the Schwinger–Keldysh formalism is applied to compute lowest-order corrections to expansion of the Universe described in terms of the spatially flat Friedman–Lemaître–Robe ...
    • Photoproduction of isolated photons, inclusively and with a jet, at HERA

    • Quantum gravity stability of isotropy in homogeneous cosmology 

      Broda, Bogusław (North-Holland, 2011)
      It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximation. Also, a formal ...
