Critical phenomena in evolutionary dynamics
… model. If the replication potential exceeds a critical value, then life replicates into existence. We continue our study of replication in Chapter 4, taking a more concrete, chemistry-oriented approach. Template-directed polymerization of nucleotides is believed to be a pathway for the …

Dynamic Critical Phenomena of the Superconducting Transition
One of the reasons why the Monte Carlo results do not accurately reproduce the dynamic exponent of the system is that a key assumption is found not to hold true. Equating Monte Carlo time to real time is believed to reproduce relaxational dynamics, but this is found not to be the case for the …

Critical Phenomena in Gravitational Collapses of Neutron Star Systems
We study critical phenomena in gravitational collapses of stellar objects based on numerical solutions of the Einstein equations. We discovered that stellar objects with large kinetic energy described by an equation of state: EOS) commonly used in describing neutron star matter may undergo critical …

Energy Emissions from Critical Phenomena and Applications to Structural Health Monitoring
The dissertation is focused on the research of critical phenomena in different size-scaled structures, from earth-scale, macro-scale to micro-scale. By analyzing the energy emission from their critical processes, some useful information or suggestion is extracted and to be provided in structural …

Study of Critical Phenomena with Monte Carlo and Machine Learning Techniques
… the results of our investigations of some of the critical dynamical properties of systems belonging to the Voter or the Directed Percolation (DP) universality class. To be more precise, we focus on the aging properties of two-state and three-state Potts models with absorbing states and we …

Numerical studies of phase transitions and critical phenomena in fermionic and polymeric systems
… we study three problems in phase transitions and critical phenomena.

An Exploration of Quantum Critical Phenomena in One-Dimensional Lattice Systems: Geometric Frustration & Quantum Fluctuations
… thesis focuses on identifying different types of critical phenomena within one-dimensional quantum lattice spin systems. People are exposed to classical critical phenomena everyday in the form of phase transitions, such as from water to ice. Surrounding quantum phase transitions, there is a number …

Phase transitions and critical phenomena: Universality and global multicritical phase diagrams from position-space renormalization-group studies
… results in studies of phase transitions and critical phenomena. Most work has focussed on the local critical properties of rather simple models. After presenting background on phase transitions and reviewing the PSRG procedure in general, we extend this approach to more complicated systems …

Properties of Neutron Star Critical Collapses
Critical phenomena in gravitational collapse opened a new mathematical vista into the theory of general relativity and may ultimately entail fundamental physical implication in the astrophysical realm, especially in gravitational collapse scenarios. However, at present, the dynamics of critical …

Temporal properties of avalanche dynamics
… avalanches in other systems are thought to be critical phenomena linked to a nonequilibrium phase transition. In this thesis we explore some temporal properties of experimental slip avalanche dynamics. These properties include aftershocks and foreshocks of slip avalanches in a bulk metallic …

Observation of the Kibble-Zurek mechanism in a bosonic gas
… provide a novel approach to the study of the critical phenomena happening at phase transitions, and introduce to the possibility of exploring the turbulent dynamics of quenched systems through the spontaneous production of solitonic vortices.

Accurate numerical relativity simulations of non-vacuumspace-times in two dimensions and applications to critical collapse
… part will use the new code to investigate the critical behaviour of two colliding neutron stars. Considering the analogy to phase transitions in statistical physics, we will investigate the evolution of the entropy of the neutron stars during the whole process. A better understanding of the …

Use solid-state NMR to study the molecular structures of disease-associated peptide aggregates
… The novel structural model can explain several critical phenomena about the cytotoxicity of the oligomers. Last, with the help from Dr. Lieberman’s lab, we explored the atomic structure of an amyloid sample—the P1 peptide amyloid derived from the residue sequence of glaucoma-associated myocilin. …

Development of a quasi-dimensional diesel engine simulation for energy and availability analysis
… and air entrainment, are developed based on critical phenomena. The model shows that predicted cylinder pressure and heat release shape are in good agreement with experimental data under rated speed and load conditions. In the radiation heat transfer model, a modified two flux model is used …

Globalization, Global Citizenship, and Catholic Education
… it is vital that these dialogues address phenomena impacting the quality of 21st century education. Among critical phenomena impacting 21st century education is globalization (Darling-Hammond, 2010; Friedman, 2005; Zhoa, 2009). In this qualitative study, phenomenological methodology was …
