      abstract     = {Electronic switches with nanoscale dimensions satisfy an
                      urgent demand for further device miniaturization. A recent
                      heavily investigated approach for nanoswitches is the use of
                      molecular junctions that employ photochromic molecules that
                      toggle between two distinct isoforms. In contrast to the
                      reports on this approach, we demonstrate that the
                      conductance switch behavior can be realized with only a bare
                      metallic contact without any molecules under light
                      illumination. We demonstrate that the conductance of bare
                      metallic quantum contacts can be reversibly switched over
                      eight orders of magnitude, which substantially exceeds the
                      performance of molecular switches. After the switch process,
                      the gap size between two electrodes can be precisely
                      adjusted with subangstrom accuracy by controlling the light
                      intensity or polarization. Supported by simulations, we
                      reveal a more general and straightforward mechanism for
                      nanoswitching behavior, i.e., atomic switches can be
                      realized by the expansion of nanoelectrodes due to plasmonic
                      heating.},
