Abstract
Macroscopic spin tunneling and quantum critical behavior of a condensate in a double-well potential were discussed. The system possessed several advantages compared to the conventional solid-state magnetic materials. The system is characterized by few simple parameters, without the complication of domain separations. The transverse field strength parameter is capable of switching on or off the tunneling. Results showed that the tunneling rate depends on the strength of the transverse field.
