Thermodynamic Phase Transitions in Finite Su-Schrieffer-Heeger Chains: Metastability and Heat Capacity Anomalies
Carlos Magno da Conceição, Julio César Pérez-Pedraza, Alfredo Raya +1
We investigate the thermodynamic properties of finite Su-Schrieffer-Heeger (SSH) chains in thermal equilibrium at fixed temperature and chemical potential. Using the canonical and…

Constraining the position of the CEP through the Speed of Sound in the LSMq
Saúl Hernández-Ortiz, Ricardo MartÃnez von Dossow, Alfredo Raya
We study the chiral phase transition within the Linear Sigma Model with quarks from its thermodynamical potential considering quantum corrections up to ring diagrams in the high-te…
