Comparative study of light storage in antirelaxation-coated and buffer-gas-filled alkali vapor cells

We perform a comparative study of light storage in antirelaxation-coated and buffer-gas-filled alkali vapor cells using electromagnetically induced transparency (EIT) in warm rubidium vapor. The use of a buffer-gas-filled cell resulted in $\approx$10-fold improvement in storage time and efficiency compared to antirelaxation-coated cells. We achieve up to sixfold enhancement in buffer-gas-filled memory efficiency, while maintaining a similar memory lifetime, by employing a near-resonant EIT $\Lambda$-scheme instead of a resonant one. Our findings contribute to the development of field-deployable quantum memories. quantum memories.Comment: 8 pages, 6 figure

Simultaneous dual-species laser cooling using an optical frequency comb

We demonstrate 1D simultaneous laser cooling of $^{87}$Rb and $^{85}$Rb atoms using an optical frequency comb. By adjusting the pulse repetition frequency and the offset frequency, the frequency comb spectrum is tuned to ensure that two distinct frequency comb modes are simultaneously red-detuned from the cooling transitions, one mode for each species. Starting from a pre-cooled cloud of $^{85,87}$Rb atoms at above-Doppler temperatures, we show simultaneous cooling of both species down to the Doppler temperature using two counter-propagating $\sigma$$^{+}$/$\sigma$$^{-}$-polarized beams from the frequency comb. The results indicate that simultaneous dual-species frequency comb cooling does not affect the cooling characteristics of individual atomic species. The results of this work imply that several atomic species could be cooled simultaneously using a single frequency comb source. This comb-based multi-channel laser cooling could bring significant advances in multi-species atom interferometers for space applications and in the study of multi-species interactions

Prevention of Conduct Disorder Do We Have Reason to Be Hopeful?

Abstract The cluster of behavior problems known as the disruptive behavior disorders, including oppositional defiant disorder and conduct disorder, represent the most common reason for referral among all childhood mental health problems. Without early preventive and intervention services, these behaviors may escalate over time, becoming more frequent, severe, and maladaptive in nature, resulting in significant and long-lasting negative consequences that affect individuals, families, schools, communities, and society in general. Historically, disruptive behavior disorders were perceived to be some of the most difficult disorders with which to intervene and ameliorate symptoms. Fortunately, evidence-based preventive and early intervention programs delivered across various settings have been developed that improve outcomes for these children and adolescents and their families

Prevention in Pursuit of Social Justice

Abstract Although prevention is in many ways aligned with social justice goals, it often falls short of accomplishing the level of social change critical for the advancement of social justice. Progress toward social justice requires a careful blend of person-focused ameliorative activity with transformative social change. Professionals must be equipped with multicultural competencies, insight into power dynamics, and skills in outreach, advocacy, collaboration, empowerment, social action, and political literacy, among other skills. Although most prevention activity is not fully transformative, numerous examples can be identified of activities that further social justice. Further strides in the promotion of social justice through prevention will require changes in the training, credentialing, and remuneration of psychologists

Promoting Resilience in Immigrants Understanding Latino/a Adaptation and Strengths

Abstract This chapter outlines adversities faced by immigrants as well as factors associated with their resilience. The Latino/a immigrant population is highlighted as the largest immigrant population in the United States. Factors contributing to resilience in this population, as well as programs and approaches used to foster well-being and resilience are discussed. Recommendations for factors to consider in promoting resilience in the Latino/a immigrant population are given, and future directions are highlighted and discussed
