Project description
Twisting light and matter to unlock quantum secrets
Controlling how quantum particles behave collectively is a challenge in physics. But it is also key to unlocking the full potential of quantum technologies. A new class of materials, van der Waals heterostructures, offers an opportunity: by rotating the stacked atomic layers at precise angles. This method, known as twistronics, can be used to tune the material’s quantum properties. With this in mind, the ERC-funded Dual-Twist project combines twistronics with optical cavities that shape how light and matter interact. The goal is to explore new quantum phases of Bosons and Bose-Fermi mixtures, to deepen our understanding of strongly interacting particles, and to pave the way for future quantum devices.
Objective
Controlling quantum correlations in many-body systems in is one of the major challenges in solid-state physics, and of critical importance for enabling applications in integrated quantum technologies. A material class that is particularly suitable to study and control the physics of correlated Bosons and Fermions are van der Waals heterostructures. These structures can be realized bottom up, layer by layer, with precision on the atomic level. Uniquely, their most fundamental electronic and quantum-optical properties can controlled via the rotation angle (‘the twist’) between the layers. This twistronic material engineering is especially suited to tailor emergent quantum correlations in van der Waals heterostructures and to control the collective quantum behavior in this novel material class.
It is the ambition of the “Dual-Twist” project to explore emergent quantum phases of Coulomb- correlated carriers and to control their interaction with precisely tailored light-fields in twistronically engineered quantum materials.
The project synergizes the emergent technique of “twistronics” to functionalize van-der-Waals heterostructures on the quantum level with the approach to utilize optical cavities to engineer quantum materials via dressing them with electromagnetic fields. Our quantum-optical investigations will provide pathways to control collective phenomena of Bose-Fermi mixtures in microcavities, correlated magnetism, collective quantum phases and strongly interacting ‘liquid light’.
Dual Twist utilizes a cavity-based quantum simulation approach to reach a deeper level of understanding in our material-based experiments. The project will develop a versatile technology to simulate the quantum behavior of interacting bosons in twist-tunable lattices of non-linear photons. Thus, it will expand our insight into the Moiré physics of correlated Bosons and will provide fundamental answers regarding their applicability in quantum information.
