A Coherent Ising Machine Based On Degenerate Optical Parametric Oscillators [PDF]

, 2013
A degenerate optical parametric oscillator network is proposed to solve the NP-hard problem of finding a ground state of the Ising model. The underlying operating mechanism originates from the bistable output phase of each oscillator and the inherent ...

Macro-micro failure and crack coalescence behavior of soft-hard composite rock with three parallel joints under uniaxial compression

Journal of Materials Research and Technology
Jointed soft-hard composite rock mass is very common in engineering. The existence of joint and the uncoordinated deformation of soft-hard layer make the failure behavior more complicated.

Jet energy loss in the quark-gluon plasma by stream instabilities

, 2009
We study the evolution of the plasma instabilities induced by two jets of particles propagating in opposite directions and crossing a thermally equilibrated non-Abelian plasma.

Disorder and excess modes in hard-sphere colloidal systems [PDF]

EPL (Europhysics Letters), 2014
The anomalous thermodynamic properties of glasses remain incompletely understood, notably the anomalous peak in the heat capacity at low temperatures; it is believed to be due to an excess of low-frequency vibrational modes and a manifestation of the structural disorder in these systems. We study the thermodynamics and vibrational dynamics of colloidal

PROBLEMS OF ENSURING QUALITY OF A SURFACE LAYER WHEN PRODUCING COMPONENTS FROM HARD-TO-PROCESS HEAT RESISTANT ALLOYS

Acta Metallurgica Slovaca, 2016
We consider the study results of the hard-to-process titanium-based alloys processing on turning lathes. The influence made on the quality of the surface layer, characterized by the amplitude roughness parameters, by geometry, cutting tool properties ...

Hard excitation mode of a system with optomechanical instability

Optics Letters
Systems with strong photon–phonon interaction and optomechanical instability are perspective for the generation of coherent phonons and photons. We predict the existence of a hard mode of excitation in such systems when a jump-like increase in the photon intensity takes place at the generation threshold.

Quasi-TEM modes in rectangular waveguides: a study based on the properties of PMC and hard surfaces

, 2008
Hard surfaces or magnetic surfaces can be used to propagate quasi-TEM modes inside closed waveguides. The interesting feature of these modes is an almost uniform field distribution inside the waveguide. But the mechanisms governing how these surfaces act,

Classical Limit for Scalar Fields at High Temperature [PDF]

, 1997
We study real-time correlation functions in scalar quantum field theories at temperature $T=1/\beta$. We show that the behaviour of soft, long wavelength modes is determined by classical statistical field theory.
