Abstract:
Atomic clocks are exceptionally versatile scientific instruments. Beyond their traditional roles in timekeeping and frequency metrology, they have emerged as powerful tools for exploring complex quantum many-body systems and as low-energy quantum sensors for tests of fundamental physics. I will give an introduction to optical ion clocks and then discuss novel ideas for probing the interplay of quantum physics and relativity in a regime where superpositions of proper time emerge [1].
