mitchell porter's latest activity

That particular paper may have gone nowhere, but the general theme of quantum deformations of string theory has had a revival in recent...

George: With the right explanation, it wouldn't take five years, or even five days, to arrive at a clearer picture. But a lot depends on...

After the news of Peter Higgs's death, I was thinking of the Higgs field and boson, how central they are to physics now, and the...

One of his more obscure honors is that in theoretical physics, he became a verb. The earliest reference I can find to being higgsed is...

In their paper they claim their theory can explain MOND, also why the cosmological constant is small but nonzero, and why the MOND...

The bridge between quantum field theory and a classical field state is something called a coherent state. Essentially, a coherent state...

I note the recent paper "Generalized Symmetry in Dynamical Gravity" (Clifford Cheung et al) which is unusual in being an advanced...

I meant reference 3. It's been noted here for many years that in Carl Brannen's eigenvalue formulation of the Koide formula, the mass...

This thread was launched by the idea of a "waterfall" of Koide-like relations that relate the masses of all the quarks as well as the...

Both the mathematical foundations and the methods of calculation are not completely figured out.

A comment on @Vanadium 50 #21. Certainly the path to the actual hydrogen atom via string theory requires first finding a string vacuum...

We could try :-) If I was doing it, I'd just try to imitate a field-theory model of the hydrogen atom using stringy ingredients. E.g...

Bound states are strings stuck to branes or branes stuck to branes. Position space probability density is the same as in QFT, except...

The archetypal string theory calculation is still the perturbative expansion of the string S-matrix for a given background, in terms of...

"The Price of Abandoning Dark Matter Is Nonlocality" (Deffayet, Woodard) written in response to "What is the price of abandoning dark...
