Perturbative dynamics of fuzzy spheres at large N
Takehiro Azuma, Keiichi Nagao, Jun Nishimura
We clarify some peculiar aspects of the perturbative expansion around a classical fuzzy-sphere solution in matrix models with a cubic term. While the effective action in the large-…
On the relation between non-commutative field theories at theta = infinity and large N matrix field theories
Wolfgang Bietenholz, Frank Hofheinz, Jun Nishimura
It is well-known that non-commutative (NC) field theories at theta = infinity are ``equivalent'' to large N matrix field theories to all orders in perturbation theory, due to the d…
Non-Commutativity of the Zero Chemical Potential Limit and the Thermodynamic Limit in Finite Density Systems
Jan Ambjorn, Konstantinos N. Anagnostopoulos, Jun Nishimura +1
Monte Carlo simulations of finite density systems are often plagued by the complex action problem. We point out that there exists certain non-commutativity in the zero chemical pot…
