Second-Order Catalytic Quasispecies Yields First-Order Phase Transition
The quasispecies model describes processes related to the origin of life and viral evolutionary dynamics. We discuss how the error catastrophe that reflects the transition from localized to delocalized quasispecies population is affected by catalytic replication of different reaction orders. Specifically, we find that 2 order mechanisms lead to 1 order discontinuous phase transitions in the via...
متن کاملReaction Paths for the Pressure-Induced Second-Order Structural Phase Transition of SnO2
Rutile represents an important structural aristotype from which numerous structures can be derived. Experimental investigation of the high-pressure behavior of metal dioxides with the rutile-type of structure (TiO2, SnO2, MnO2, ZrO2, RuO2, PbO2) led to a large body of work in the past 20 years. The above mentioned oxides undergo several structural phase transitions (SPT's) under pressure. In pa...
متن کاملEvolution of fields in a second order phase transition.
We analyse the evolution of scalar and gauge fields during a second order phase transition using a Langevin equation approach. We show that topological defects formed during the phase transition are stable to thermal fluctuations. Our method allows the field evolution to be followed throughout the phase transition, for both expanding and non-expanding Universes. The results verify the Kibble me...
متن کاملFormation of Topological Defects in a Second Order Phase Transition
The classical evolution equations of the Abelian Higgs model are studied at temperatures below the Ginsburg temperature of a phase transition which is assumed to be second order. It is shown that the initial thermal fluctuations provide a domain structure which is stable against late time fluctuations. This result lends support to the Kibble mechanism for the formation of topological defects.
متن کاملSecond-order scaling in the two-flavor QCD chiral transition.
Scaling behavior is analyzed for the two-flavor QCD lattice gauge theory chiral transition. Leading scaling behavior and correction to leading scaling from lattice spacing effects are examined for the quark condensate. Scaling predictions under the assumption of quark mass dominance are tested for the longitudinal correlation length. Second order scaling behavior is consistent with present data...
