Ellipsometry with polarisation analysis at cryogenic temperatures inside a vacuum chamber
S. Bauer, B. Grees, D. Spitzer +9
In this paper we describe a new variant of null ellipsometry to determine thicknesses and optical properties of thin films on a substrate at cryogenic temperatures. In the PCSA arr…
Hard Loops, Soft Loops, and High Density Effective Field Theory
Thomas Schaefer
We study several issues related to the use of effective field theories in QCD at large baryon density. We show that the power counting is complicated by the appearance of two scale…
Instantons in QCD with Many Colors
Thomas Schaefer
We study instantons in QCD with many colors. We first discuss a number of qualitative arguments concerning the large N_c scaling behavior of a random instanton ensemble. We show th…
Instantons and the Large N_c Limit of QCD
Thomas Schaefer
We summarize our current understanding of instantons in the large N_c limit of QCD. We also present some recent results from simulations of the instanton liquid in QCD for N_c>3.
Mass Terms in Effective Theories of High Density Quark Matter
Thomas Schaefer
We study the structure of mass terms in the effective theory for quasi-particles in QCD at high baryon density. To next-to-leading order in the expansion we find two types…
High Density Quark Matter under Stress
P. F. Bedaque, T. Schaefer
We study the effect of SU(3) flavor breaking on high density quark matter. We discuss, in particular, the effect a non-zero electron chemical potential and a finite strange quark m…
