    Solvability of subprincipal type operators

    Full text link
    In this paper we consider the solvability of pseudodifferential operators in the case when the principal symbol vanishes of order k≥2k \ge 2 at a nonradial involutive manifold Σ2\Sigma_2. We shall assume that the operator is of subprincipal type, which means that the k k:th inhomogeneous blowup at Σ2\Sigma_2 of the refined principal symbol is of principal type with Hamilton vector field parallel to the base Σ2\Sigma_2, but transversal to the symplectic leaves of Σ2\Sigma_2 at the characteristics. When k=∞k = \infty this blowup reduces to the subprincipal symbol. We also assume that the blowup is essentially constant on the leaves of Σ2\Sigma_2, and does not satisfying the Nirenberg-Treves condition (Ψ{\Psi}). We also have conditions on the vanishing of the normal gradient and the Hessian of the blowup at the characteristics. Under these conditions, we show that PP is not solvable.Comment: Changed the formulation of Theorem 2.15, added an assuption. Corrected errors and clarified the arguments. Added reference

    Static and Dynamic Spectroscopy of (Al,Ga)As/GaAs Microdisk Lasers with Interface Fluctuation Quantum Dots

    Full text link
    We have studied the steady state and dynamic optical properties of semiconductor microdisk lasers whose active region contains interface fluctuation quantum dots in GaAs/(Ga,Al)As quantum wells. Steady-state measurements of the stimulated emission via whispering gallery modes yield a quality factor Q∼5600Q \sim 5600 and a coupling constant β∼0.09\beta \sim 0.09. The broad gain spectrum produces mode hopping between spectrally adjacent whispering gallery modes as a function of temperature and excitation power. Time- and energy-resolved photoluminescence measurements show that the emission rise and decay rates increase significantly with excitation power. Marked differences are observed between the radiative decay rates in processed and unprocessed samples.Comment: To appear in Phys. Rev.

    Project Management with a Purpose: Delivering Project Management Education through Service Learning

    This research describes the development of an introduction to project management (IPM) course taught in the business college of a Midwestern University. Due in part to an educational initiative launched by the University, the IPM was revised to follow a service-learning model. Following an overview of service-learning pedagogy, related theoretical perspectives, benefits, and practical considerations, we describe the prior learnings on implementing service-learning in project-based courses and in particular, the development of the IPM course and our intentions to develop a model of student outcomes of service-learning for project management education. We collected surveys from 85 undergraduate and graduate students enrolled in the course to examine student attitudes toward service-learning, impacts of service-learning, and adoption of project management career skills due to participation in the service-learning project. We intend to analyze the student data in order to identify the key constructs and relationships that affect learning outcomes

    Dynamics of Entanglement and the Schmidt Gap in a Driven Light-Matter System

    Full text link
    The ability to modify light-matter coupling in time (e.g. using external pulses) opens up the exciting possibility of generating and probing new aspects of quantum correlations in many-body light-matter systems. Here we study the impact of such a pulsed coupling on the light-matter entanglement in the Dicke model as well as the respective subsystem quantum dynamics. Our dynamical many-body analysis exploits the natural partition between the radiation and matter degrees of freedom, allowing us to explore time-dependent intra-subsystem quantum correlations by means of squeezing parameters, and the inter-subsystem Schmidt gap for different pulse duration (i.e. ramping velocity) regimes -- from the near adiabatic to the sudden quench limits. Our results reveal that both types of quantities indicate the emergence of the superradiant phase when crossing the quantum critical point. In addition, at the end of the pulse light and matter remain entangled even though they become uncoupled, which could be exploited to generate entangled states in non-interacting systems.Comment: 15 pages, 4 figures, Accepted for publication in Journal of Physics B, special issue Correlations in light-matter interaction
