Stochastic Model of Breakdown Nucleation under Intense Electric Fields [PDF]

open access: yesPhys. Rev. Lett. 120, 124801 (2018), 2018
Plastic response due to dislocation activity under intense electric fields is proposed as a source of breakdown. A model is formulated based on stochastic multiplication and arrest under the stress generated by the field.

On the Electric Breakdown in Liquid Argon at Centimeter Scale [PDF]

open access: yes2016 JINST 11 P03017, 2016
We present a study on the dependence of electric breakdown discharge properties on electrode geometry and the breakdown field in liquid argon near its boiling point. The measurements were performed with a spherical cathode and a planar anode at distances

Phase-field modeling and machine learning of electric-thermal-mechanical breakdown of polymer-based dielectrics

open access: yesNature Communications, 2019
Polymer dielectrics are promising for high-density energy storage but dielectric breakdown is poorly understood. Here, a phase-field model is developed to investigate electric, thermal, and mechanical effects in the breakdown process for a range of ...

Investigation on different materials after pulsed high field conditioning and low-energy H- irradiation [PDF]

open access: yesFrontiers in Physics
During operation, the radio-frequency quadrupole (RFQ) of the LINAC4 at CERN is exposed to high electric fields, which can lead to vacuum breakdown. It is also subject to beam loss, which can cause surface modification, including blistering, which can ...

Electrical Breakdown of Excitonic Insulators [PDF]

open access: yesPhysical Review X, 2023
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 ...

Breakdown of an Electric-Field Driven System: a Mapping to a Quantum Walk [PDF]

open access: green, 2004
Quantum transport properties of electron systems driven by strong electric fields are studied by mapping the Landau-Zener transition dynamics to a quantum walk on a semi-infinite one-dimensional lattice with a reflecting boundary, where the sites ...
