Walter R. L. Lambrecht

Walter R. L. Lambrecht serves as the Perkins Professor of Physics in the Department of Physics at Case Western Reserve University's College of Arts and Sciences, specializing in first-principles condensed matter theory and computational materials science.

His academic credentials include:

• Lic. Sc. from the University of Gent (1977)
• Dr. Sc. from the University of Gent (1980)

Dr. Lambrecht's research centers on reducing material properties to electronic structure through quantum mechanics and statistical mechanics. He applies density functional theory (DFT) and many-body perturbation theory (MBPT) to investigate semiconductor nitrides, halide perovskites for photovoltaics, layered 2D materials (MoS₂, V₂O₅), oxide interfaces, point defects, rare-earth compounds, and semiconductor nanowires. His group develops computational tools including the linearized muffin-tin orbital method and GW approximation, collaborating closely with experimentalists to solve material puzzles and predict new properties.

Analysis of his 2007-2015 publications reveals consistent focus on computational modeling of novel materials, particularly using GW methods for electronic structure calculations. Key trends include exploration of 2D systems' dimensionality effects, halide perovskites' photovoltaic mechanisms, and defect physics in semiconductors, demonstrating strong theory-experiment integration across diverse material classes.

His work has received recognition through multiple Editor's Suggestion designations in Physical Review B for high-impact publications.

Dr. Lambrecht leads the active Lambrecht Research Group and has secured research funding including an NSF World Materials Network grant for rare-earth nitride studies in collaboration with Victoria University of Wellington. He maintains significant computational collaborations, particularly with Mark van Schilfgaarde at Arizona State University for code development and implementation of advanced methods like quasiparticle self-consistent GW.

The research group utilizes specialized computational frameworks including the full-potential linearized muffin-tin orbital method and density functional perturbation theory (ABINIT code), with ongoing development of tools for strongly correlated systems and complex material interfaces.
