We report nonperturbative results for the interacting quantum-critical behavior in a Bose-Fermi Kondo model describing a spin1 2 coupled both to a fermionic band with a pseudogap density of states and to a dissipative bosonic bath. The model serves as a paradigm for studying the interplay between Kondo physics and low-energy dissipative modes in strongly correlated systems.

We study eigenfrequencies and propagator expansions for damped wave equations on compact manifolds. In the strongly damped case, the propagator is shown to admit an expansion in terms of the finitely many eigenmodes near the real axis, with an error exponentially decaying in time. In the presence of an elliptic closed geodesic not meeting the support of the damping coefficient, we show that the...

A method for evaluating the stability of a metric for determining the health of armor plates is presented. The metric is based on the following basic premise: The amplitudes and locations of the major vibrational modes of an undamaged armor plate constitute a basic “signature” of the armor plate. Damaging the armor plate should cause changes to both the amplitude and position of the significant...

Using data from extensive vibrational tests of the new aircraft Saab 2000 a combined method for vibration analysis is studied. The method is based on a realization algorithm followed by standard prediction error methods (PEM). We nd that the realization algorithm gives good initial model parameter estimates that can be further improved by the use of PEM. We use the method to get insights into t...

In most recent free oscillation studies of the earth's interior the effect of absorption upon the eigenperiods of the earth has been ignored. This is equivalent to assuming that the earth is close to perfectly elastic. Since the actual earth is significantly anelastic over seismic frequencies, a frequencydependent correction of the order of 1% must be applied to the normal mode periods in order...

Web browsers are the most common tool to perform various activities over the internet. Along with normal mode, all modern browsers have private browsing mode. The name of the mode varies from browser to browser but the purpose of the private mode remains same in every browser. In normal browsing mode, the browser keeps track of users’ activity and related data such as browsing histories, cookie...

The main thesis of this paper is that reasoning about measurements can be used as a basic mechanism for generating test plans for analogical circuits. Motivated by an application scenario, reasoning about measurements incorporates domain knowledge about testing conditions, local behavior of circuit components (fault modes covered by measurements) and the topological structure of the circuit to ...

In this article we present and test a model for large microring resonators based on implementation of the bidirectional Eigenmode Expansion Method for rigorous modelling of vectorial field propagation in the coupling region and using accurate solutions for the bend mode propagating in the ring.
