Towards the cold atom analog false vacuum

Understand

Analog condensed matter systems present an exciting opportunity to simulate early Universe models in table-top experiments.

• We consider a recent proposal for an analog condensed matter experiment to simulate the relativistic quantum decay of the false vacuum.
• In the proposed experiment, two ultra-cold condensates are coupled via a time-varying radio-frequency field.
• The relative phase of the two condensates in this system is approximately described by a relativistic scalar field with a potential possessing a series of false and true vacuum local minima.
