My research has been in pursuit of understanding novel quantum phenomena in low dimensional materials with a particular focus on two dimensional (2D) materials. My work has primarily contributed to understanding novel correlated and topological properties of Dirac electrons in atomically thin graphene layers, their twisted structures and those confined in circular graphene resonators or quantum dots (QD). The next important task is to acquire the meaningful scientific insights required for the advancement of technologies based on quantum physics.
In this context, Ghahari’s lab aims to address some of the important fundamental questions about interaction effects, quantum statistics and topology in correlated phases of matter. To pursue this objective, our current research focuses on two directions: I) Realizing specific device structures with precise nanoscale electrostatic control which allow probing specific characteristics of emergent phases, II) entropic and thermal sensitive detection of correlated phenomena which provide direct access to thermodynamic properties of the system.
We employ innovative techniques to enable engineering clean layered heterostructures with tunable dimensionalities and novel device architectures for thermal sensitive measurements. The quantum phenomena in these specific geometries/structures are being studied employing different techniques such as electrical transport and thermal measurements, tuning experimental knobs such as temperature, electric and magnetic fields.
Our research can have important implications in development of innovative quantum devices and advancement of quantum information technologies such as design of new types of qubits and topological quantum computing schemes.
