Adiabatic Preparation of a Chiral Spin Liquid — •Moritz Schlechtriem, Francesco Petiziol, and André Eckardt — Technische Universität Berlin, Institut für Theoretische Physik, Hardenbergstraße 36, 10623 Berlin, Germany

Efficient protocols to prepare spin-liquid states are essential for exploring these phases of matter and harnessing their potential for applications. The goal of this study is to investigate the adiabatic preparation of a chiral spin liquid ground state on the Kagome lattice. Considering different easily-realizable initial Hamiltonians and different system sizes, the minimal duration for a high-fidelity adiabatic transition into the spin-liquid phase is determined and optimal adiabatic paths are explored. In a second step, the analysis is extended to the case in which the spin-liquid Hamiltonian is realized via Floquet engineering.
