Research on Monitoring Methods for Electrostatic Discharge Pulses in Spacecraft Dielectric Materials

open access: yesMicromachines
Space particle radiation induces charging and discharging phenomena in spacecraft dielectric materials, leading to electrostatic discharge (ESD) and electromagnetic pulses (EMP), which pose significant risks to spacecraft electronic systems by causing ...

Vacuum energy and $\theta$--vacuum

open access: yes, 2003
The highly non-trivial structure of the $\theta$--vacuum encodes many of the fundamental properties of gauge theories. In particular, the response of the vacuum to the $\theta$--term perturbation is sensitive to the existence of confinement, chiral symmetry breaking, etc.
