Mean field theory and Hartree
... Here D̂ contains the “direct” terms, and Ê contains the “exchange” terms. The third part of both D̂ and Ê is an average, not an operator, and doesn’t affect dynamics, just total energy. It can be dropped for now. The first two terms of both D̂ and Ê are identical, after re-labeling indices, and a ...

More on the MASS GAP and YANG-MILLS
... So my solution is not a bridging of the mass gap, it is a tearing down of the mass gap. I have shown that the problem is a manufactured problem, created only by faulty math. There is no mass gap because there is no limit at c, and there is no limit at c because gamma has been in the wrong form from ...

To get a holomorphic picture of all the D simultaneously you have to consider the twistor family of Q, which is of complex dimension 3 and roughly glues together all the complex structures of Q: inside there we could identify the BPS states as holomorphic curves w ...

Kondo Screening Cloud Around a Quantum Dot

The screening of an impurity spin by conduction electrons, the Kondo effect, is believed by many to be associated with the formation of a ‘‘screening cloud’’ around the impurity with a size K vF =TK where vF is the Fermi velocity and TK is the Kondo temperature, the characteristic energy scale as ...
