Can you show me where I should put the code that you write? I'm tried but still no success.

You need to move the display of the date field outside of the foreach loop. Alternatively check if the same date has already been displayed before displaying each item.
So start with an empty date field:

PHP

$lastdate = "";
foreach ...
    $year = strtotime($publications['publication_year']));
    if ($year != $lastdate) {
        $lastdate = $year;
    // it's a different year so display it
    }
    // display the individual publications
} // end of foreach
