摘要:

标准模型中高能粒子碰撞时的Sphaleron动力学在实验上仍未被观测到,其理论预测因非微扰实时性质而受阻。在本工作中,我们研究了一种应对此挑战的量子模拟方法。以$1+1$D $O(3)$模型作为研究电弱理论中sphaleron动力学的方案,我们识别了sphaleron构型,并建立了能够以受控精度重现连续sphaleron能量的格点参数。随后,我们开发了量子算法来模拟可包含量子效应的sphaleron演化。本工作为建立量子模拟以研究量子场论中经典拓扑物体与粒子之间的相互作用奠定了基础,这些相互作用通常无法通过经典方法和计算获得。

英文摘要:

Sphaleron dynamics in the Standard Model at high-energy particle collisions remains experimentally unobserved, with theoretical predictions hindered by its nonperturbative real-time nature. In this work, we investigate a quantum simulation approach to this challenge. Taking the $1+1$D $O(3)$ model as a protocol towards studying dynamics of sphaleron in the electroweak theory, we identify the sphaleron configuration and establish lattice parameters that reproduce continuum sphaleron energies with controlled precision. We then develop quantum algorithms to simulate sphaleron evolutions where quantum effects can be included. This work lays the ground to establish quantum simulations for studying the interaction between classical topological objects and particles in the quantum field theory that are usually inaccessible to classical methods and computations.
