Classical approaches to prethermal discrete time crystals in one, two, and three dimensions

Andrea Pizzi, Andreas Nunnenkamp, Johannes Knolle

We provide a comprehensive account of prethermal discrete time crystals within classical Hamiltonian dynamics, complementing and extending our recent work [Phys. Rev. Lett. 127, 14…

Berry curvature-induced local spin polarisation in gated graphene/WTe heterostructures

Lukas Powalla, Jonas Kiemle, Elio J. König +6

Full experimental control of local spin-charge interconversion is of primary interest for spintronics. Heterostructures combining graphene with a strongly spin-orbit coupled two-di…

Classical Prethermal Phases of Matter

Andrea Pizzi, Andreas Nunnenkamp, Johannes Knolle

Systems subject to a high-frequency drive can spend an exponentially long time in a prethermal regime, in which novel phases of matter with no equilibrium counterpart can be realiz…

Variational quantum algorithm with information sharing

Chris N. Self, Kiran E. Khosla, Alistair W. R. Smith +5

We introduce an optimisation method for variational quantum algorithms and experimentally demonstrate a 100-fold improvement in efficiency compared to naive implementations. The ef…

The one-dimensional Long-Range Falikov-Kimball Model: Thermal Phase Transition and Disorder-Free Localisation

Thomas Hodson, Josef Willsher, Johannes Knolle

Disorder or interactions can turn metals into insulators. One of the simplest settings to study this physics is given by the Falikov-Kimball model, which describes itinerant fermio…

Flat and Correlated Plasmon Bands in Graphene/-RuCl Heterostructures

Hui-Ke Jin, J. Knolle

We develop a microscopic theory for plasmon excitations of graphene/-RuCl heterostructures. Within a Kondo-Kitaev model with various interactions, a heavy Fermi liquid hos…
