Multiple conditions? cant figure it..

Im using Thesis Framework and I have this code which works great, the only problem is I need this code to work for the home page as well, is_home? but i cant seem to target home as well as what it already targets, could anyone take a look at it and help me out?

Thanks

function archive(){
    if(is_archive()){

        echo '<div class="three-teaser-row">';
        $args = array(
            'posts_per_page' => 15,
            'post_type' => 'post'
        );
            $my_query = new WP_Query($args); while ($my_query->have_posts()) : $my_query->the_post(); $do_not_duplicate = $post->ID;

            thesis_teaser('teaser', $post_count = false, $right = false);

            endwhile;
            echo '</div>';
        } else {
            thesis_loop::archive();
        }
    }
}

new my_archive_loop;
