# Biblatex, number followed by dot in bibliography

I'm using BibTeX and biblatex for my documents. I'm now writing an article and am required to write the bibliography with the following style:

1. C. Tsallis et al., Phys. Rev. A 63 (2001) 042104.

While rest of the style can be achieved using the biblatex-phys package, I don't know how to set the style for the reference number, i.e. how to change [1] to 1.

-

\DeclareFieldFormat{labelnumberwidth}{#1\adddot}
\setlength{\biblabelsep}{5pt}


MWE:

\documentclass{article}

\usepackage[style=phys,biblabel=brackets]{biblatex}
\setlength{\biblabelsep}{5pt}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
\end{filecontents}
