Lecture 2: Electronics and Mechanics on the Nanometer Scale
... Electronic waves, like ordinary waves, experience a set of multiple reflections as they move back and forth between two barriers. The total probability amplitude for the transfer of a particle can be viewed as a sum of amplitudes, each corresponding to escape after an increasing number of “bounces” ...

... magnetic field. This unexpected behavior results from the interactioninduced modification of the band structure which leads to formation of the compressible strips in the middle of GNRs. We show the existence of the counter-propagating states at the same half of the GNRs. The overlap between these sta ...

Real-time evolution for weak interaction quenches in quantum systems
... system, once initialized in a pure state defined by 1 Tr½q any later point in time because of the cyclic property of the trace.3 Due to the linearity of the trace, the same holds for any time average. Hence quantum systems are never ergodic in a classical sense. This limitation does not apply for t ...

Coherent Decay of Bose-Einstein Condensates
... manifests itself as a collective decay of the assembly as a whole. As a signature of this phenomenon, there arises a complex chemical potential in which the imaginary part quantifies a coherent decay into collective phonon excitations of a collapsing ground state. The unique decay rate dependencies ...
