Dynamics of entanglement entropy of interacting fermions in a 1D driven harmonic trap

Following up on a recent analysis of two cold atoms in a time-dependent harmonic trap in one dimension, we explore the entanglement entropy of two and three fermions in the same situation when driven through a parametric resonance. We find that the presence of such a resonance in the two-particle system leaves a clear imprint on the entanglement entropy. We show how the signal is modified by attractive and repulsive contact interactions, and how it remains present for the three-particle system. Additionaly, we extend the work of recent experiments to demonstrate how restricting observation to a limited subsystem gives rise to locally thermal behavior.Comment: Proceedings of Lattice2017, Granada, Spai

Evaluating Leadership Development Through Experiential Learning In A Virtual Environment

The strategic leadership center of a senior military service college collaborated with an elite law school to provide leadership development to senior law school students. The focus was an International Strategic Crisis Negotiation Exercise set in the South China Sea. Due to an unexpected global health pandemic the course was forced online to a virtual environment. The strategic leadership center gathered data from volunteer students and their mentors to determine the impact of the virtual setting. Using four archival datasets, a program evaluation was conducted using a case study methodology to determine the effectiveness of experiential learning through simulation in a virtual environment and to gain an in-depth understanding of its impact on the development of the leadership soft skills of teamwork, communication, and negotiation techniques for senior law school students from the perspective of students and their mentors. The research study found that experiential learning through simulation in a virtual environment was highly effective and transformative. The interpretation of the ten findings is enlightening and contributes to a more complete understanding of experimental learning. The significance of the study is its contribution to leadership education, legal education, and education policies
