Hessian in the spinfoam models with cosmological constant
Wojciech Kamiński, Qiaoyin Pan
In this paper, we introduce a general method to prove the non-degeneracy of the Hessian in the spinfoam vertex amplitude for quantum gravity and apply it to the spinfoam models wit…

Complex Chern-Simons Theory with and An Improved Spinfoam Model with Cosmological Constant
Muxin Han, Qiaoyin Pan
This paper presents an improvement to the four-dimensional spinfoam model with cosmological constant (-SF model) in loop quantum gravity. The original -SF model, defined via…

Geometrical Reconstruction of Spinfoam Critical Points with A Cosmological Constant
Qiaoyin Pan
In this work, we present a geometrical reconstruction of the critical points of the spinfoam amplitude for a 4D Lorentzian model with a non-zero cosmological constant. By establish…
