Lanatà Research

We are seeking a highly motivated MS student to join our team at the RIT School of Physics and Astronomy under the supervision of Dr. Nicola Lanatà. Our research project aims to develop a method for accurately and efficiently computing the properties of strongly correlated materials using quantum mechanics principles and models. These materials are of great interest in fields such as condensed matter physics, materials science, and chemistry, due to their complex behavior that cannot be explained by traditional methods.

This is an opportunity to learn about the application of quantum mechanics principles and models to real material applications and to contribute to the development of a cutting-edge method for studying these materials. You will work with a team of experienced researchers, and have the opportunity to collaborate with colleagues at Rutgers University and the Center for Computational Quantum Physics (CCQ). Your responsibilities will include implementing and testing the method using simple systems such as the Hubbard model and then progressing to more complex systems in the second phase.

The project utilizes the ghost Gutzwiller Approximation (g-GA) method in combination with density functional theory to study these materials. We will also be testing the Gutzwiller renormalization group as an impurity solver, for improving the accuracy and computational efficiency of the g-GA. The goal is to improve our understanding of strongly correlated materials and unlock new possibilities for their study.

For students interested in working on a project with the potential to significantly advance the field of strongly correlated quantum matter, contact Dr. Nicola Lanatà.

We are seeking a highly motivated MS student to join our team at the RIT School of Physics and Astronomy under the supervision of Dr. Nicola Lanatà. Our research project aims to develop a method for accurately and efficiently simulating quantum-mechanical systems using a hybrid quantum-classical framework called Variational Quantum Eigensolver (VQE). These algorithms have the potential to enable broader applications in fields such as condensed matter physics, chemistry, and materials science, but are currently limited by noise from decoherence and hardware imperfections.

This is an opportunity to contribute to cutting-edge research at the forefront of the field by using probabilistic machine learning to mitigate this noise in VQE algorithms. This will improve the reliability of quantum computing and unlock new possibilities for simulations of large molecules and solids. Your responsibilities will include developing and testing the probabilistic machine learning method for noise mitigation in VQE, as well as applying this method to quantum computing devices.

You will work with a team of experienced researchers, and have the opportunity to contribute to the development of a cutting-edge method for studying the quantum matter. If you are passionate about exploring the potential of quantum computing and machine learning and are interested in working on a project with the potential to significantly advance the field, contact Dr. Nicola Lanatà.
