A Critique of “A Critique of Two Metals”
... The “Critique” [1] contains in its first few paragraphs an elegant, if somewhat incorrect, statement of the issues between us and the school which believes, almost religiously, in the quantum critical point as the solution to all our woes in the cuprates. The fundamental argument is presented in the ...

From a set of targets given by high-level ab initio quantum chemistry for representative clusters undegoing the phenomena of interest, create a one-particle (short-range) Hamiltonian, that can represent them. It should be composed of none or a few atomic parameters. Once the (second-quantized) Hamil ...

In other words, one must take the limit, when the advanced time v = t + r tends to +00, or the retarded time ...
