I had a quick look and couldn't see a specific API for this.
You could always run a search with size 1 and the physical index name should be returned as part of matching documents' properties.

My code is:

		// get name of the current index where the alias is active
		GetAliasesResponse r = client.admin().indices().getAliases(new GetAliasesRequest().aliases("YOUR_ALIAS")).get();

		for(Iterator<String> it = r.getAliases().keysIt(); it.hasNext();) {
			// HERE IS THE REALINDEXNAME
			String realIndexName = it.next();
		}
