摘要:

超冷原子系统凭借其更高的操控性和运行条件的灵活性,已成为各类与开发及实现量子技术相关的量子系统中的有力候选者。本论文中,我们探究了在强相互作用N分量费米子(即所谓的SU(N)费米子)的环形量子气体中产生的持续电流。我们的研究结果除了对多体物理具有相关贡献外,还证实了基于SU(N)费米子平台的物质波电路这一新概念的“第一推动力”,开启了原子电子学领域令人振奋的新篇章。实际上,其特有的量子化特性有望为制造具有更高灵敏度的量子器件(如干涉仪)提供核心支撑。同时,SU(N)费米子电路在利用这种人工费米子物质构建冷原子量子模拟器方面展现出应用前景。

英文摘要:

Ultracold atomic systems have emerged as strong contenders amongst the various quantum systems relevant for developing and implementing quantum technologies due to their enhanced control and flexibility of the operating conditions. In this thesis, we explore persistent currents generated in a ring-shaped quantum gas of strongly interacting \textit{N}-component fermions, specifically the so-called SU(\textit{N}) fermions. Our results, apart from being a relevant contribution to many-body physics, prove the `primum mobile' for a new concept of matter-wave circuits based on SU(\textit{N}) fermionic platforms, opening an exciting chapter in the field of atomtronics. Indeed, the specific properties of quantization are expected to provide the core to fabricate quantum devices with enhanced sensitivity like interferometers. At the same time, SU(\textit{N}) fermionic circuits show promise in engineering cold atoms quantum simulators with this artificial fermionic matter.
