Contribution

It applies both canonical and microcanonical ensembles to analyze black cosmic strings, highlighting their thermodynamic properties and stability regimes in anti-de Sitter spacetime.

Findings

Existence of black string/thermal radiation equilibrium regimes

Identification of stable remnant regimes

Comparison with Schwarzschild-AdS and BTZ black holes

Abstract

Both the canonical and microcanonical ensembles are utilized to study the thermodynamic and evaporation properties of a closed black cosmic string whose spacetime is asymptotically anti deSitter. There are similarities and differences to the Schwarzschild-anti deSitter and 2+1 BTZ black hole solutions. It is found that there exist regimes of black string/thermal radiation equilibrium as well as stable remnant regimes. The relevance to black hole evaporation is discussed.
