Shortcuts to adiabatic Thouless pumping

Thouless pumping, the quantized transport of particles in a cyclic adiabatic evolution, faces a challenge: slow driving may exceed the coherent time, while fast driving may break quantization. To address this dilemma, we propose to speed up Thouless pumping using shortcuts to adiabaticity. By using counterdiabatic theory, we analytically derive the controlled Hamiltonian for implementing dispersion-suppressed Thouless pumping beyond the adiabatic regime. Compared to traditional Thouless pumping methods, our fast topological pumping approach offers remarkable advantages. Firstly, it enables a substantial reduction of pumping time up to 11 orders of magnitude faster than the traditional approach. Secondly, our method effectively suppresses wavepacket diffusion, further enhancing its efficiency. Furthermore, we demonstrate the resilience of our protocol against moderate noise levels. Our study offers a practical and efficient method for achieving fast topological pumping beyond the adiabatic regime.
