Lattice models are mathematical frameworks used to study various physical systems by discretizing space into a grid-like structure, allowing for the analysis of complex phenomena such as phase transitions and critical behavior. They are widely used in statistical mechanics, quantum field theory, and financial mathematics to provide insights into the behavior of systems under different conditions.

Complex phenomena refer to systems or events characterized by intricate interdependencies and unpredictable behaviors, often arising from the interactions of multiple components. Understanding such phenomena typically requires interdisciplinary approaches and computational models to capture their emergent properties and dynamic nature.

Phase transitions are transformations between different states of matter, such as solid, liquid, and gas, characterized by abrupt changes in physical properties. These transitions occur at specific conditions of temperature and pressure, and are often associated with critical phenomena and symmetry breaking.

phase transitions

Critical behavior refers to the phenomena observed near continuous phase transitions, where systems exhibit scale invariance and universality. These behaviors are characterized by critical exponents and scaling laws, which describe how physical quantities diverge or vanish as the system approaches the critical point.

Statistical mechanics is a branch of physics that uses probability theory to study and predict the behavior of systems with a large number of particles, bridging the microscopic laws of physics with macroscopic observations. It provides the framework for understanding thermodynamic properties and phase transitions by averaging over the possible states of a system rather than tracking individual particles.

Quantum Field Theory (QFT) is a fundamental framework in theoretical physics that blends quantum mechanics with special relativity to describe how particles and fields interact. It serves as the foundation for understanding particle physics and the Standard Model, providing insights into the behavior of subatomic particles and the forces that govern them.

Financial mathematics is the application of mathematical methods to solve problems in finance, such as pricing derivatives, managing risk, and optimizing investment portfolios. It combines techniques from probability, statistics, and calculus to model financial markets and make informed financial decisions.
