Group Website
Our research interests are wide ranging and include the novel laser fabrication of thin films and coatings of advanced materials for electronics, sensors, biomaterials, and for energy storage. The new materials were used in device configurations for testing and typically had an improved figure-of-merit. He is considered one of the pioneers in the field of Pulsed Laser Deposition and was the lead inventor of MAPLE processing technique (matrix assisted pulsed laser evaporation). He is currently publishing in areas of metallic nanoparticle fabrication, biosensing, bionanotechnology, tissue engineering, stem cell processing, ceramics, and polyamorphism.
Experimental Solid State Physics
Principal Investigator: David L. Ederer (Emeritus)
Tulane Group Members: Tim Schuler
Professor David L. Ederer was a senior staff scientist in the Center for Atomic, Molecular and Optical Physics at the National Institute of Standards and Technology (NIST), for almost thirty years. He came to Tulane in January 1992 to launch a new program in experimental solid state physics with the Center for Advanced Microstructures and Devices (CAMD) in Baton Rouge, as a focal point. Ederer carries out research on transition metals and rare earth materials at the Advanced Light Source as well, using soft x-rays to elucidate the electronic properties of complex and highly correlated materials such as high Tc superconductors. Ederer, a fellow of the American Physical Society, is an internationally recognized expert in the use of synchrotron radiation for research in atomic, molecular, and solid state physics. His research in atomic, and condensed matter physics, as well as instrument design has resulted in over one hundred and fifty papers.
Recent topics of research have included doped manganate systems, the superconducting perovskite Sr2RuO4 system and multi-layered variants, and magnetically doped semiconductors with particular focus on half-metallic behaviour.
Photonic Materials & Devices
Principal Investigator: Matthew Escarra
Tulane Group Members: Kazi Islam, Isaac Oguntoye, Timothy Ismael, Siddarth Padmanabha, William Skelton, Meghan Bush, Brittany Simone, and Claire Luthy
Group Website
The Escarra group explores novel photonic materials and devices with applications particularly, but not exclusively, in the area of solar energy conversion. On the fundamental end, we are exploring nanoscale photonic materials and devices, where quantum phenomena tend to dominate, for potential use as light emitters, photovoltaics, and more. We are also interested in nanostructured materials, where sub-wavelength, or nanophotonic, behavior determines optical properties. On the applied end, we are developing unique material, device, and system architectures for ultra-high efficiency solar energy conversion.
Active project thrusts include:
In collaboration with academic and industry partners, the group is developing a new hybrid solar energy converter that allows for high efficiency, dispatchable renewable energy production. This system features a spectrum splitting photovoltaic module designed to work in tandem with solar thermal energy capture and storage.
The group is exploring a nanophotonic approach to splitting the solar spectrum, enabling ultra-high efficiency solar energy conversion. This research area focuses on low-loss photonic micro/nanostructures for sculpting the flow of light, leading to improved light absorption and more efficient use of the full solar spectrum.
The group is studying two-dimensional transition metal chalcogenides and their quantum phenomena for use as semiconductor materials in ultra-thin optoelectronic devices. We have a particular interest in heterostructures of 2D materials and ternary transition metal chalcogenides.
The work in this group involves optical, thermal, and device physics simulations, micro/nanofabrication, and optoelectronic material and device characterization.

research includes several directions surrounding the fields of quantum information technologies, machine learning, and optical communications. Some examples include developing and applying neural networks to classical and quantum communications, multi-party quantum networks, and quantum state estimation. One core aspect of this research is to improve our understanding of the fundamental physics surrounding quantum entanglement and quantum states of light, which are integral to the creation of future quantum networks. A second aspect involves utilizing these concepts in various computation, communication, and measurement protocols to enhance performance beyond classical limits. We are also developing machine learning tools for enhancing a variety of classical and quantum optical systems and protocols.
One experimental tool used in this research is four-wave mixing in warm atomic vapor. This process generates pairs of photons in separate spatial modes that exhibit stronger correlations than allowed by classical physics, in multiple degrees of freedom. When a laser is used to seed the process, bright “twin beams” of light are created. The correlations in these twin beam states are exploited to enhance, for example, interferometric measurements and the resolution of imaging systems. Investigating novel methods to generate highly multimode “squeezed” and entangled light is an important aspect of this research area, applicable to quantum networks.
We also have several projects involving the combination of machine learning, optical communications (both classical and quantum), and quantum measurement. This includes advancing current state-of-the-art free-space optical communications systems, enhancing quantum state estimation protocols, and the development of quantum networks.
The group is also interested in the generation of novel high-dimensional entangled states of light. This work involves creating robust continuous-variable states that are applicable to real-world systems in which scattering and decoherence are present. The fundamental behavior of the quantum information present in these states is a key theme in this research.
Novel Energy Materials
Principal Investigator: Michael Naguib
The need for reliable energy conversion and storage systems is continuously growing, especially with recent efforts to further develop renewable energy and the explosive growth of portable device technologies. Thus, the development of novel materials for energy conversion and storage is of critical importance. Thus, the research in our group has the general theme of Novel Energy Materials. This involves developing new 2D materials for applications in the next generation of batteries beyond Li-ion, supercapacitors and electrocatalysis. In addition to discovering and creating new materials, another important thrust is developing inexpensive materials for the commercially available electrochemical energy storage systems (e.g. Li-ion batteries and supercapacitors), that contributing to environmentally friendly and sustainable technologies.
