A fluid model of self-gravitating strings is proposed. It expected that black holes turn into around the end hole evaporation. The transition will occur near Hagedorn temperature. After transition, would form a bound state by self-gravitation. Horowitz and Polchinski formulated using winding wrapping on Euclidean time circle [Phys. Rev. D 57, 2557 (1998)]. In this paper, we first show in Horowi...

A simple model of a " black hole interior " , namely a spherically symmetric solution of the Einstein field equations in matter matching the Schwarzschild vacuum at a spacelike hypersurface " R < 2M " is constructed. The model is physically valid: it describes an elastic–solid sphere having a well–defined equation of state and satisfying the weak energy condition. G. Magli, A simple model of a ...

We study the dynamics of holes and defects in the 1D complex Ginzburg-Landau equation in ordered and chaotic cases. Ordered hole-defect dynamics occurs when an unstable hole invades a plane wave state and periodically nucleates defects from which new holes are born. The results of a detailed numerical study of these periodic states are incorporated into a simple analytic description of isolated...

In models with extra dimensions, a black hole evaporates both in the bulk and on the visible brane, where standard model fields live. The exact emissivities of each particle species are needed to determine how the black hole decay proceeds. We compute and discuss the absorption cross sections, the relative emissivities, and the total power output of all known fields in the evaporation phase. Gr...

This work presents a simple model of via-hole using electromagnetic field solver. Equivalent model parameters on Si are found out at Ka-band. Proposed single via-hole model has been compared with theoretical published data. The effect of viahole radius and substrate height at Ka-band frequencies has been studied. Further, S-parameter analysis and comparison for multiple vias at two different fr...

For minimally coupled scalars at low frequencies, the D-brane model has the same spectrum of radiation as the Hawking radiation from a black hole. We perform a similar comparison for another type of scalar which we call an intermediate scalar. In this case, we find that there is a discrepancy between the D-brane model and the black hole even for very low frequency scalars. This suggests that th...

We study Lorentzian D-particles in linear dilaton and the two dimensional black hole backgrounds. The D-particle trajectory follows an accelerated trajectory which is smeared by stringy corrections. For the black hole background we find that the portion of the trajectory behind the horizon appears to an asymptotic observer as ghost D-particle. This suggests a way of constructing a matrix model ...

We perform the numerically exact diagonalization study of the t-J model with nonmagnetic impurities to clarify the relation between Zn impurities and the stripes. By examining the hole-hole correlation function for a two-hole √ 18× √ 18 cluster with a single impurity, we find that the impurity has a tendency to stabilize vertical charge stripes. This tendency is caused by the gain of the kineti...

Both the localized resonance and excitation of spoof surface plasmon polaritons are observed in the terahertz transmission spectra of periodic subwavelength hole arrays. Analyzing with the coupled oscillator model, we find that the terahertz transmission is actually facilitated by three successive processes: the incident terahertz field first initiates the localized oscillation around each hole...

Recent progress in numerical relativity has enabled us to model the nonperturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a phenomenological family of waveforms which can model the inspiral, merger, and ring-down stages of black hole coalescence. We also construct a template bank using this family of waveforms and discuss its implementatio...
