US Patent 11069790 Quantum tunneling matter-wave transistor system

The present invention provides an matter-wave transistor in which the flow of particles (e.g., atoms and molecules) through the transistor is a result of resonant tunneling from a source well, through a gate well and into a drain well (as opposed to being a result of collisions, as in a classical atomtronic transistor). The transistor current of matter-wave particles can be controlled as a function of the breadth of resonant tunneling conditions of the gate well. For example, the resonant tunneling conditions of a gate well that does not include a dipole-oscillating Bose-Einstein condensate (DOBEC) can be broadened by including a DOBEC in the gate well. Similarly, the breadth of resonant tunneling conditions of the gate well can be changed by changing the particle population of a DOBEC in the gate well.
