Bound states in single and double Y-junction quantum dot.

POSTER

Abstract

We present the solution of quantum-mechanical problem of a particle in Y-junction quantum dot. The single bound state with Dirichlet Laplacian is described. The bound state presence is examined for the case of junction being asymmetric, i.e. going from C3V to C2v group when the width of one of the ligament is increased. We further investigated the solution of two connected Y-junction with two bound states. These finding could be useful for building 2D two-level systems for quantum qubits or quantum waveguide applications.
