Thermal phase transitions for Dicke-type models in the ultra-strong coupling limit

We consider the Dicke model in the ultra-strong coupling limit to investigate thermal phase transitions and their precursors at finite particle numbers $N$ for bosonic and fermionic systems. We derive partition functions with degeneracy factors that account for the number of configurations and derive explicit expressions for the Landau free energy. This allows us to discuss the difference between the original Dicke (fermionic) and the bosonic case. We find a crossover between these two cases that shows up, e.g., in the specific heat.Comment: 4 pages Brief Report styl

An Intersectional Approach to Latino Anti-Violence Engagement

Men’s perspectives on nonviolence is a relatively rare topic of feminist research. This article examines Latinos’ pathways to a commitment to nonviolent masculinities within intimate relationships. Examining literature on nonviolence and drawing on interviews with six Latinos the article uses a feminist ecological approach to identify and examine contributing factors to “emergent masculinities” characterized by a commitment to nonviolence in intimate relationships. It examines experiences of marginalization, exposure to domestic violence, and the influence of a close woman mentor as factors that contribute to a commitment to nonviolence. It also critiques the common equation of the absence of physical violence with nonviolence as it examines how even among self-identified nonviolent men it is possible to identify some forms of violence against intimate partners
