项目摘要
This is an extension of the Fellowship "Coherent quantum matter out of equilibrium - from fundamental physics towards applications". The original project concerned collective phenomena in a wide range of photonic systems to explore the fundamental properties of matter and their use for device applications. The extension will now focus on systems of strongly interacting and massive photons, placed in artificially made lattice potentials mimicking real solids, and their use as quantum simulators. Ever since the idea of quantum simulations, which involves the creation and control of simpler systems to model the behaviour of more complex and poorly understood systems, have been proposed, the search for suitable physical platforms has been one of the most active branches of Quantum Technologies. Due to their light mass, photons have been shown to exhibit quantum effects at high, up-to-room temperatures and can be easily integrated with other platforms for technological applications. Thus, the idea of creating synthetic quantum matter out of photons to simulate poorly understood lattice systems, such as real solids, has been particularly attractive. However, photons cannot be perfectly trapped and decoupled from their environment, which leads to non-equilibrium dissipative conditions, that are challenging to describe if combined with strong interactions and correlations, but particularly relevant for real life applications. The main aim of the project is to devise effective new theoretical and computational methods to treat strong correlations and entanglement in driven-dissipative lattice systems of photons in collaboration with experimental groups, and to use these methods to design protocols for experimental exploration of those in the spirit of quantum simulation. We will focus on two particularly promising platforms: polariton lattices i.e. specially engineered semiconductor structures, and superconducting circuits coupled to microwave photons. Our research will address fundamental problems of phase transitions, orders, symmetry and topology when strong interactions combine with strong dissipation and non-equilibrium conditions, as well as practical questions how correlations form and propagate, and how they can be controlled and protected from the destructive influence of the outside world.
这是联谊会“脱离平衡的相干量子物质--从基础物理到应用”的延伸。最初的项目涉及广泛的光子系统中的集体现象,以探索物质的基本性质及其在设备应用中的用途。扩展现在将专注于强相互作用和大质量光子的系统,放置在模拟真实固体的人工制造的晶格势中,以及它们作为量子模拟器的使用。自量子模拟的想法提出以来,寻找合适的物理平台一直是量子技术最活跃的分支之一。量子模拟涉及创建和控制更简单的系统,以模拟更复杂和更难理解的系统的行为。由于其轻质量,光子已被证明在高温下表现出量子效应,并可以很容易地与其他平台集成在一起,用于技术应用。因此,用光子创造合成量子物质来模拟人们鲜为人知的晶格系统,例如真实的固体,这一想法特别有吸引力。然而,光子不可能完全被捕获并与其环境解耦,这导致了非平衡耗散条件,如果结合强烈的相互作用和关联,这些条件很难描述,但与现实生活应用特别相关。该项目的主要目的是与实验小组合作,设计有效的新的理论和计算方法来处理光子驱动耗散晶格系统中的强关联和纠缠,并本着量子模拟的精神使用这些方法来设计实验探索的协议。我们将集中在两个特别有前景的平台:极化晶格,即特殊设计的半导体结构,以及与微波光子耦合的超导电路。我们的研究将解决强相互作用与强耗散和非平衡条件相结合时的相变、有序、对称性和拓扑等基本问题,以及关联如何形成和传播,以及如何控制和保护它们免受外部世界破坏性影响的实际问题。
