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…
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…
