Previous Research

Conductance quantization in the presence of backscattering
with H.Heyszenau. Found simple realization of a quantum constriction in a magnetic field displaying accurate conductance plateaux despite the fact that none of its transmission eigenvalues are unity.
Resonances and continuum bound states in an open quantum dot
with H.Heyszenau. Investigated the effect of a magnetic-field induced nonintegrable perturbation on bound states in the continuum which arise due to a classical conservation law in a quantum dot with leads attached to it; found resonance widths tunable by magnitude of magnetic field.
Linear response theory and the Landauer formula
with A.D.Stone and H.U.Baranger. Showed that contrary to the claim of a recent Physical Review Letter by F.Sols, linear response theory in open conductors is gauge invariant without the need for a modified continuity equation, and that the Landauer-Büttiker formula can be obtained consistently from this starting point.
Resonance lineshapes in quasi-one-dimensional scattering
with A.D.Stone. Investigated the limitations of the coupled-channel (Feshbach) scattering theory in microstructures with two ideal leads, and applied S-matrix theory to multilead, multichannel geometries to make general predictions about the possible effects that resonant states can have on the conductance of a microstructure; proposed a transport experiment on a groove in a two-dimensional electron gas with a magnetic field parallel to it.
Fano resonances in the linear conductance of a quantum well in a tilted magnetic field
with A.D.Stone. Proposed a heterostructure experiment on a shallow quantum well without barriers that exhibits narrow asymmetric resonances due to inter-Landau-level transitions whose width depends on the tilt angle of the applied magnetic field.
Ray Chaos in Asymmetric Resonant Cavities (ARC)
with A.D.Stone, R.K.Chang, A.Mekis, and G.Chen. Proposed a ray-optics model to explain the Q-factors and anisotropic emission patterns of dielectric cavities when they are deformed from rotationally invariant shapes. Applied the KAM theory of the transition to Hamiltonian chaos to predict a threshold deformation for Q-spoiling as well as power-law degradation of Q above this threshold. Found experimental agreement with expected emission directionality of deformed lasing droplets.
"Wave Chaos" in Asymmetric Resonant Cavities
with A.D.Stone and G.Hackenbroich. Confirmed the existence of a threshold deformation for Q-spoiling and the classically predicted directionality patterns by numerical solution of the wave equation for dielectric cylinders with strongly deformed cross-section at small wavelengths. Observed wave corrections to the ray predictions for resonance lifetimes; identified them as manifestations of "chaos-assisted tunneling" and "dynamical localization", thus providing a novel type of system in which to study these phenomena theoretically and experimentally.
Quantum-cascade microcylinder lasers with oval cross-section
With E.E. Narimanov, C.Gmachl, F. Capasso, A.D.Stone et al.. Used methods from nonlinear dynamics to aid in the design and interpetation of unipolar semiconductor microlasers with overall dimensions below 100 μm and world-record output power for their size.
Effects of sample-size and resorvoir width on the AC admittance of small conductors
with Klaus Richter. Starting from linear response theory, rederived Büttiker's scattering formulation of external and internal response in AC transport, generalizing to include the interplay of inelastic processes and finite reservoir width.
Hexagonal zeolite-dye microcrystals as microlasers
with U. Vietze, F. Laeri et al. Calculated the spectral and spatial properties of lasing modes in self-assembled microcrystalline lasers with low pump threshold and diameters below 8 μm, thus explaining experimentally observed emission directionality, free spectral range and Q-factors.
Quantum well lasers using metallic-mirror microresonators
with I. Abram et al. Identified a new dome-shaped cavity design for which the scalar wave problem is integrable, and derived some special exact solutions for modes of the full vectorial electromagnetic problem as well. Used chaotic phase-space analysis to investigate the effect of shape distortions on the mode structure, in particular regarding the leakage through a Bragg mirror bounding the cavity from below.
Design of passive optical resonator devices (WDM, filters, switches, directional couplers)
at Nanovation Technologies, Inc. Investigated the coupling problem between resonator devices and adjacent optical components on Indium Phosphide based electro-optic integrated circuits.
Non-perturbative classical phase space structure in nearly spherical optical microresonators
with Scott Lacey, Hailin Wang and David Foster. Performed numerical simulations and theoretical analysis to explain the experimentally observed strong directionality of light output from fused-silica resonators that are only weakly deformed from the limiting case of spherical symmetry where no such directionality is to be expected.
