The Scholar's Study
Welcome to the academic sanctum of Dr. Davood B. Dar, Lore-master of Theoretical Realms, where the fundamental mysteries of quantum mechanics and molecular dynamics are unraveled.
Ascended to the rank of PhD at the venerable Rutgers University, my quest has been to chart the unseen forces that govern the microscopic realms, wielding the twin blades of theory and computation to illuminate nature's most elusive patterns.
This sanctuary serves as a beacon for fellow truth-seekers, collaborators across the academic realms, and seekers of knowledge in the domains of theoretical physics and chemistry.
Domains of Inquiry
Time-Dependent Density Functional Theory (TDDFT)
Developing novel formulations to solve long-standing challenges in nonperturbative quantum dynamics, such as the Rabi oscillation problem and excited-state curve crossings. My work provides more accurate descriptions of electron dynamics under strong external fields.
Electronic Structure & Excited States
Exploring the dance of electrons in molecules, particularly in excited states. My research focuses on capturing elusive phenomena like double excitations and curve-crossing events in conjugated systems, advancing our understanding of photochemical processes.
Nonperturbative Quantum Dynamics
Developing robust theoretical frameworks to describe quantum systems under strong external perturbations where traditional perturbative approaches fail. This includes exact treatments of few-electron systems and practical approaches for many-electron systems.
Response Theory & Memory Effects
Investigating the fundamental aspects of time-dependent density-functional response theory, particularly addressing divergences and incorporating crucial memory effects in quadratic and higher-order responses that govern nonlinear optical phenomena.
