Hi everyone, I apologize if the answer to this question is more simple than I am able to realize, but I've searched the internet and haven't found much on the possibility of inducing quantum mechanical tunneling. Is it possible to affect the probability of this event without altering the object's mass or the distance to its objective? Thanks for any input.

Yes change the barrier thickness and or energy.

You have already done this thousands of times whenever you save something on flash memory. It is induced tunnel although that term is not used.

Note not all memory devices work like this.

Sorry, by distance to objective I believe i meant barrier thickness as well. Is there any other factor?

Yes.

You calculate the tunnelling probability from the distance, the initial conditions, and the potential that appears in the Hamiltonian, and many things other than the object's mass enters into the Hamiltonian. Change the initial conditions, height and/or shape of the potential barrier and you will get different tunnelling probabilities.

(I have changed the thread level from I to B)
