    "abstract": "We show that a noninvasive,``negative-result measurement\u0027\u0027 can be realized in\nquantum dot systems. The measurement process is studied by applying the\nSchr\\\"odinger equation to the whole system (including the detector). We\ndemonstrate that the possibility of observing a particular state out of\ncoherent superposition leads to collapse of the corresponding nondiagonal\ndensity-matrix elements of the measured system. No additional reduction\npostulate is needed. Experimental consequences of the collapse time and the\nrelativistic requirement are discussed for mesoscopic and optical systems.",
