"Quantization" of higher hamiltonian analogues of the Painleve I and Painleve II equations with two degrees of freedom
Quantization higher hamiltonian analogues Painleve I Painleve II equations Exactly Solvable and Integrable Systems

2010/12/24
We study the thermodynamic properties of horizons using the dynamical description of the gravitational degrees of freedom at a horizon derived in an earlier work. We use the action of the horizon degr...

We define a set of boundary conditions that ensure the presence of a null hypersurface with the
essential characteristics of a horizon, using the formalism of weakly isolated horizons as a guide.We t...

Interplay of Spin Lattice Degrees Temperature Induced Anomalies
2010/11/24
Temperature and magnetic field studies of the elastic constants of the chromium spinel CdCr2O4
show pronounced anomalies related to strong spin-phonon coupling in this frustrated antiferromagnet.A de...

We present an efficient arbitrary polarization qubit transmission scheme against channel noise
by utilizing frequency degree of freedom, which is more stable in transmission surroundings. The informa...
