3D Ising Model on Dual BCC Lattice: the Sign-Factor
J. Ambjorn, Sh. Khachatryan, A. Sedrakyan
The 3d Ising model on a regular cubic lattice can be expressed in terms of an SU(2) 2d fermionic model with a -fluxes. We modify the model such that it is defined on the dual…
Real--time dynamics of a hot Yang-Mills theory: a numerical analysis
J. Ambjorn, K. N. Anagnostopoulos, A. Krasnitz
We discuss recent results obtained from simulations of high temperature, classical, real time dynamics of SU(2) Yang-Mills theory at temperatures of the order of the electroweak sc…
Lorentzian 3d Gravity with Wormholes via Matrix Models
J. Ambjorn, J. Jurkiewicz, R. Loll +1
We uncover a surprising correspondence between a non-perturbative formulation of three-dimensional Lorentzian quantum gravity and a hermitian two-matrix model with ABAB-interaction…
Dynamically Triangulating Lorentzian Quantum Gravity
J. Ambjorn, J. Jurkiewicz, R. Loll
Fruitful ideas on how to quantize gravity are few and far between. In this paper, we give a complete description of a recently introduced non-perturbative gravitational path integr…
Monte Carlo Studies of the Dimensionally Reduced 4d SU(N) Super Yang-Mills Theory
J. Ambjorn, K. N. Anagnostopoulos, W. Bietenholz +2
We simulate a supersymmetric matrix model obtained from dimensional reduction of 4d SU(N) super Yang-Mills theory. The model is well defined for finite N and it is found that the l…
High-temperature, classical, real-time dynamics of non-abelian gauge theories as seen by a computer
J. Ambjorn, K. N. Anagnostopoulos, A. Krasnitz
We test at the electroweak scale the recently proposed elaborate theoretical scenario for real-time dynamics of non-abelian gauge theories at high temperature. We see no sign of th…
