We are supported by the National Research Foundation (NSF) to do fundamental theoretical research on quantum chaotic systems.We study revivals of wavepackets in classical systems such as the stadium billiard. We study the fidelity (overlap) decay of wave systems propagated through two slightly perturbed systems and characterize the degree of chaos of the system by using results derived from the kicked rotor. On the application side, we study quantum dots and the coulomb blockade. The shape of the confinement area for an electron in a quantum dot can cause the electron's movement to be chaotic within the dot, much as the shape of a billiard controls the amount of chaos for a billiard ball. We also study electron branched flow and parity violations in nuclear physics. |
