摘要

我们使用非微扰晶格蒙特卡罗计算研究了Berenstein-Maldacena-Nastase矩阵模型的热相结构。我们的主要分析跨越了耦合的3个数量级，涉及大小高达Nτ=24晶格位的系统和8≤N≤16的SU(N)规范群。此外，我们对Nτ≤128和量规群SU(4)的离散伪像进行了扩展检验。我们发现了在弱耦合下的微扰预测和强耦合下的大n双超重力计算之间插值的解定义温度结果。在强耦合条件下，相变是一阶的，而在弱耦合条件下，相变是连续的。2025年由美国物理学会出版

Finite-temperature phase diagram of the Berenstein-Maldacena-Nastase matrix model on the lattice

We investigate the thermal phase structure of the Berenstein-Maldacena-Nastase matrix model using nonperturbative lattice Monte Carlo calculations. Our main analyses span 3 orders of magnitude in the coupling, involving systems with sizes up to Nτ=24 lattice sites and SU(N) gauge groups with 8≤N≤16. In addition, we carry out extended checks of discretization artifacts for Nτ≤128 and gauge group SU(4). We find results for the deconfinement temperature that interpolate between the perturbative prediction at weak coupling and the large-N dual supergravity calculation at strong coupling. While we confirm that the phase transition is first order for strong coupling, it appears to be continuous for weaker couplings.
