Extended Hořava Gravity with Physical Ground-State Wavefunction

We propose a new extended theory of Hořava gravity based on the following three conditions: (i) power-counting renormalizable, (ii) healthy IR behavior and (iii) a stable vacuum state in a quantized version of the theory. Compared with other extended theories, we stress that any realistic theory of gravity must have physical ground states when quantization is performed. To fulfill the three conditions, we softly break the detailed balance but keep its basic structure unchanged. It turns out that the new model constructed in this way can avoid the strong coupling problem and remains power-counting renormalizable, moreover, it has a stable vacuum state by an appropriate choice of parameters.

3. Attrition and exhaustion

Two of the more frequently used military strategies are attrition and exhaustion. Attrition means reducing an adversary’s physical capacity to fight; exhaustion entails wearing down the opponent’s willingness to do so. Both strategies can mean long wars, imposing heavy burdens on a nation’s population and economy, meaning they are not always culturally acceptable or economically practical. The Allies’ strategy in the Second World War is a modern example of attrition. A strategy of exhaustion can take several forms: blockades, sieges, guerrilla warfare, and “scorched earth” policies that destroy the physical ground an attacker might use. Physical and political geographies in the region will affect the implementation of either strategy.

BUILDING AN ENTANGLEMENT MEASURE ON PHYSICAL GROUND

We introduce on physical grounds a new measure of multipartite entanglement for pure states. The function we define is discriminant and monotone under LOCC; moreover, it can be expressed in terms of observables of the system.

THE MASS RELATION BETWEEN THE PURE AND PHYSICAL GROUND PSEUDOSCALAR GLUEBALLS

The experimental information indicates that for the ground pseudoscalar states, the omission of the transition amplitudes between quarkonia can result in the unreasonable result. It is believed that the mass of the pure glueball employed in the general form of the mass matrix is different from the mass predicted by lattice QCD in quenched approximation for the ground pseudoscalar glueball. The mass relation between the pure and physical ground pseudoscalar glueballs is determined from the experimental data.

ADMITTANCE FIELD METHOD FOR THE CALCULATION OF THE SPECTRAL DENSITY OF CURRENT FLUCTUATIONS

In the framework of the Green-function formalism the admittance field method is proposed for the calculation of the spectral density of current fluctuations of two and more terminal devices. The usefulness of the theory is illustrated by hydrodynamic calculations performed for a submicron GaAs structure. The unifying property of the formalism evidences the same physical ground of both the admittance and impedance field methods when instantaneous fluctuations of carrier accelerations during scattering events are taken as noise sources.

The Role of Interfacial Polarization in the Electrorheological Effects

The conductive, dielectric and surface properties of severl water-free polymer or inorganic material based ER fluids, as well as their response times, are investigated to elucidate the physical ground of the electrorheological effect. It is found that the slow polarization, especially the interfacial polarization rather than the Debye polarization, should be responsible for the observed phenomena. Combining with the recent achievements (both theoretical and experimental) in the electrorheological field, we argue that is the interfacial polarization that does play a central role in electrorheological response. The particle re-orientation process is actually resulted from the large interfacial polarization.
