Reply to comment by Auphor_Phaksache in TIL black holes also regurgitate matter such as stars that they suck in by Desolecontra

Yes they can be created spontaneously .. but only for very brief periods while the universe isn't paying attention. Then they recombine and the ledger is balanced. What is possible near the event horizon, is the anti-particle can cross the event horizon leaving the normal particle outside. It can escape (it also might not, but it can). If it does then the books still balance because the anti-particle robs the black hole of the exact mass of the particle.

Not sure what you mean by 'force applied away from the black hole'.

The article suggest that the particles are being ejected away from the black hole. What force cause the particles to drive away from the black hole and not into it? Is it reacting off the anti particle?

Can spontaneous particle creation be replicated using tech?

The ones in the article are 'regular' matter that is in the accretion disk. That's ejected by centripetal force. Gets sucked in close and some of it loses angular momentum and falls into the hole. Some of it gains that same momentum and is flung out.
As for replicating particle creation, I don't think so, but I'm not 100% sure of this stuff. I went back and edited the original because your questions are triggering some vague memories that I might be conflating different things.
