Introduction to ligand field theory (Ballhausen. Carl J.)

Carl J. Carl J. Levinson, MD, 1927–2011

With such a mentor, we are pushed to become much more than we could have been, to strive to achieve beyond ourselves. Carl exemplified this in his character not only for SLS and me but also in other organizations and places, such as AAGL, in Milwaukee, at Baylor, in San Francisco, and ultimately at Stanford. He influenced many leaders in the field today. To name just a few: Camran Nezhat, Rober...

Introduction to effective field theory

The basic idea behind effective field theory (EFT) methods is to describe nature in terms of a fully consistent quantum field theory, but one which is valid in a limited energy range. Now strictly speaking this means that almost any theory is an EFT except string theories that try to be a theory of everything (TOE). Indeed even the quintessential quantum field theory—quantum electrodynamics—is ...

Introduction to Noncommutative Field Theory

But what is it exactly? Let us motivate the problem in a mathematical way: consider the Gel’fand-Naimark duality theorem, a mathematical theorem which establishes a one-to-one correspondence between topological (Hausdorff) spaces X and commutative C∗-algebras A=C(X), where A is the algebra of continuous complex-valued functions f : X → C with the pointwise multiplication (f.g)(x) = f(x).g(x). G...

Introduction to spherical field theory

Spherical field theory is a new non-perturbative method for studying quantum field theories. It uses the spherical partial wave expansion to reduce a general d-dimensional Euclidean field theory into a set of coupled onedimensional systems. The coupled one-dimensional systems are then converted to partial differential equations and solved numerically. We demonstrate the methods of spherical fie...
