a Hydrogen atom exposed to an electric field. We also demonstrate that a similar addition to the tunneling ionization rate occurs in the 3D Coulomb-Stark(CR) problem i.e. Our calculations strongly suggest that this non-adiabatic correction to the tunneling ionization can be significant even for long-wavelength excitation, and that it could account for a source of seed electrons in the avalanche ionization which is important for optical filamentation experiments with long-wavelength lasers. Taking advantage of our exact solutions, we were able to rule out some of the competing theories.We also identified a non-adiabatic contribution to tunneling ionization, an effect neglected in strong field light-matter interaction studies so far. Answering these problems requires connecting the quantum and classical descriptions of the electrons liberated from atoms, molecules, and nano-structures by strong electric fields. These investigations provided us with valuable insights into long-debated problems related to quantum tunneling, namely, the quantum tunneling time and momentum i.e., the ongoing debate in the literature about how much time a particle spends in the classically forbidden region during the tunneling process and what is its momentum when it emerges from the classically forbidden region. This study explores exactly solvable models for the light-matter interactions in the strong-field regime.
This study has the potential to make theoretical contributions to the psychological literature on environmental justice issues, but also practical contributions to public health and advocacy in Tucson’s southside community.
Some forms of social capital such as social support and neighborhood social cohesion also moderated various negative mental health impacts of exposure to historic contamination. The results of this study suggest that residents potentially exposed to historic contamination over forty years ago experience somewhat elevated levels of depression, post-traumatic stress, historical trauma, disruption in core beliefs, and environmental risk perceptions, but also higher life satisfaction.
Measures included mental distress and wellbeing (stress, life satisfaction, depression), trauma (historical trauma, post-traumatic stress, disruption in core beliefs), environmental risk perceptions, efficacy, denial, environmental justice concerns, and social capital (social support, neighborhood social cohesion, civic engagement, and trust in institutions). A survey (n = 363) using door-to-door and social media recruitment methods compared those who were potentially exposed to historical contamination to non-exposed southside residents and non-exposed residents of central Tucson. This dissertation focused on the community stress experience related to historic contamination on the Tucson International Airport Area Superfund site in Tucson’s southside, a predominantly low-income and Latinx community. However, these events represent an often-overlooked environmental justice issue in the psychology literature. The experience of chronic environmental contamination is an increasingly prevalent environmental hazard faced by communities around the world with deleterious physical and mental health outcomes.
