Revealing string patterns in the doped Hubbard model

Detecting string patterns

In our recent article we present experimental results for the doped Fermi-Hubbard model at the lowest currently achievable temperatures. We detect string patterns and explain their doping-dependence by a surprisingly simple but elegant geometric string paradigm. This method only utilizes data at half filling and works for all consider doping values between 0 and 30 % hole doping.

The results have been published in Science:
