Noncyclic geometric phase in three-level Ramsey interferometry for enhanced metrology
Zhifan Zhou, Yaxin Li
In a standard two-level Ramsey interferometer, the accumulated signal phase is linearly mapped to the readout phase. Here, we introduce three-level Ramsey interferometry, in which…
Observation of Anomalous Moiré Patterns
Omer Amit, Or Dobkowski, Zhifan Zhou +6
Moiré patterns are omnipresent. They are important for any overlapping periodic phenomenon, from vibrational and electromagnetic, to condensed matter. Here we show, both theoretica…
Realization of a complete Stern-Gerlach interferometer
Yair Margalit, Zhifan Zhou, Or Dobkowski +4
The Stern-Gerlach (SG) effect, discovered almost a century ago, has become a paradigm of quantum mechanics. Surprisingly there is little evidence that the original scheme with free…
Quantum complementarity of clocks in the context of general relativity
Zhifan Zhou, Yair Margalit, Daniel Rohrlich +2
Clocks play a special role at the interface of general relativity and quantum mechanics. We analyze a clock-interferometry thought experiment and go on to theoretically derive and…
