The remarkable precision of optical atomic clocks offers sensitivity to new and exotic physics. In this talk I will explain the motivation and operating principles of the multiplexed optical lattice clock, which consists of two or more clocks in one vacuum chamber. This miniature clock network enables us to bypass the primary limitations to typical atomic clock comparisons and achieve new levels of precision. I will present recent experimental results in which we performed a novel, blinded, precision test of the gravitational redshift with an array of atomic ensembles spanning a total height difference of 1 cm. Finally, I will discuss the outlook for future searches for new physics with our apparatus.
