boldfontsitalic
In the following documentclass
\documentclass[prb,twocolumn,showpacs]{revtex4}
how to have italic and bold in a subsection title?
The italic command removes the boldness when inside a subsection, so I tried the following :
\subsection{Short-range {\bf {\it vs}} long-range scattering}
It does not work.
Any idea how to solve this?
Maybe the documentclass has nothing to do with it, I did not check it.
You can put this in the preamble, without the need to define new theorem styles; in fact this redefines the plain and definition theorem styles in order that the theorem title has the same font attributes as the theorem heading:
\usepackage{amsthm}
\makeatletter
\def\th@plain{%
\thm@notefont{}% same as heading font
\itshape % body font
}
\def\th@definition{%
\thm@notefont{}% same as heading font
\normalfont % body font
}
\makeatother
In your log file you will find warnings like
LaTeX Font Warning: Some font shapes were not available, defaults substituted.
This means you don't use a font which has such a combination. See: Warning: “Font shape … not available”
Load \usepackage[T1]{fontenc} and you will get:

This has nothing to do with the documentclass, but with font selection.
\itselects non-bold italics, and\bfselects non-italic bold. You should useinstead. See also this question.
