Avalanches in Breakdown and Fracture Processes

, 1999
We investigate the breakdown of disordered networks under the action of an increasing external---mechanical or electrical---force. We perform a mean-field analysis and estimate scaling exponents for the approach to the instability.

Impulse breakdown delay in liquid dielectrics [PDF]

, 2012
Theoretical images of streamers, revealing the mechanisms behind impulse breakdown in liquid dielectrics, are presented. Streamers lead to electrical breakdown by forming paths, capable of carrying large current amplitudes between electrodes.

Electrical breakdown mechanism and life prediction of thermal-aged epoxy/glass fibre composites

Polymer Testing
Epoxy/glass fibre composites possess excellent mechanical and electrical properties and are widely utilised in electrical and electronic power equipment. However, the composites exhibit relatively poor thermal conductivity, causing the temperature of the

Nuclear spin coherence in a quantum wire

, 2009
We have observed millisecond-long coherent evolution of nuclear spins in a quantum wire at 1.2 K. Local, all-electrical manipulation of nuclear spins is achieved by dynamic nuclear polarization in the breakdown regime of the Integer Quantum Hall Effect ...

Characterization of the susceptibility of ore particles to breakdown in high voltage pulse breakage and the influencing factors

International Journal of Mining Science and Technology
The susceptibility of ore particles to electrical breakdown plays a critical role for high voltage pulse (HVP) breakage, yet its quantitative characterization still lacks deep understanding.

Electrical Breakdown of Excitonic Insulators

Physical Review X
We propose a new electrical breakdown mechanism for exciton insulators in the BCS limit, which differs fundamentally from the Zener breakdown mechanism observed in traditional band insulators. Our new mechanism results from the instability of the many-body ground state for exciton condensation, caused by the strong competition between the polarization ...

Effects of grading tungsten powders on properties of CuW alloy

Materials Research Express, 2020
Considering the advantages and disadvantages of CuW alloys with different single particle size of tungsten powder, CuW alloys with three kinds of tungsten powders: ultramicron (50 μ m), micron(6–8 μ m), submicron(0.4 μ m) were prepared by the ...
