Logistic cellular automata
(Bilkent University, 2019-09)Cellular Automata (CA), initially formalized to investigate self-reproducing constructions, are among the most frequently used tools to model and understand complex systems. These computational frameworks are de ned in ... -
Phase transitions and renormalization-group theory
(1989-07)The study of critical phenomena targets the qualitatively new phenomena that occur through the interactions of very large numbers of degrees of freedom. Such situations are typically realized near the onset of the transition ... -
Quantum phase transitions from analysis of the polarization amplitude
(American Physical Society, 2019)In the modern theory of polarization, polarization itself is given by a geometric phase. In calculations for interacting systems the polarization and its variance are obtained from the polarization amplitude. We interpret ... -
Scaling and renormalization in the modern theory of polarization: application to disordered systems
(American Physical Society, 2021-12-15)We develop a scaling theory and a renormalization technique in the context of the modern theory of polarization. The central idea is to use the characteristic function (also known as the polarization amplitude) in place ... -
Synthesis of V2 O3 nanoplates for the exploration of the correlated supercritical state
(American Physical Society, 2019)Peculiar features exist in the stress-temperature phase stability diagram of V2O3, such as a first-order phase transition between the paramagnetic insulating and metallic phases that ends with a critical point, quantum ...
