With that kind of fundamental science I would expect no practical applications but guidance for researchers that work on practical applications.
There are many ideas on how the universe works, right? Knowing which ideas are closer to the truth must be helpful to people who work on nano scale stuff, like chips so fine that quantum effect are considerable.
It must be somewhere between knowing if there's alien life or not AND knowing that atoms can be split at sub particles at will.
What actually happens is, smart people are isolated from the problems of the general population and work towards meaningless goals at the cost of the everyday tax payer doing unglamorous work to earn a living. Decoupling science from the state will also reduce the meaningless competition of academia that leads to the publish-or-perish and replication crises, because the people who will be doing it, will do it for the love of the game, regardless of social status and money.
If you want to live in this world, you have to trade your time and provide value to others. You shouldn't get a free pass because, just because you convinced yourself and the government that you're smarter than everyone else.

Sorry, no. That's solid state physics on inter-atomic scales: tenths of nanometers, a handful of electronvolts. The LHC probes physics at the electroweak scale: hundreds of billions of electronvolts, billionths of nanometers. It has zero relevance to anything of practical use.
