The emergence of (3+1)-dimensional expanding spacetime from complex Langevin simulations of the Lorentzian type IIB matrix model with deformations

Konstantinos N. Anagnostopoulos, Takehiro Azuma, Mitsuaki Hirasawa +3

The Lorentzian type IIB matrix model is a promising candidate for a nonperturbative formulation of superstring theory. In this model, the eigenvalue distribution of the $N \times N$ …

Non-Linear Sigma Model and asymptotic freedom at the Lifshitz point

K. Anagnostopoulos, K. Farakos, P. Pasipoularides +1

We construct the general O(N)-symmetric non-linear sigma model in 2+1 spacetime dimensions at the Lifshitz point with dynamical critical exponent z=2. For a particular choice of th…
