Aravind Karthigeyan

Center for Complex Quantum Systems

Spring 2023 - Present

Advisor: Keji Lai

• Studied the development of exfoliation, band theory, microwave engineering, and electric/magnetic materials under the mentorship of graduate students and postdocs
• Currently contributing to project to analyze excitons in ReS₂ and heterostructures of WS₂ and WSe₂
• Few-layer exfoliation, stacking, and transfer of TMDs and hBN
• Experienced in Microwave Impedance Microscopy, a technique to measure impedance and conductance at the mesoscale noninvasively

Quantum Computing

Spring 2023 - Present

Advisor: Noah Davis

• Studied the basics of quantum computation and implemented several algorithms, such as Deutsch–Jozsa, Simon's, Phase Estimation, Shor's, and Grover's algorithms on Qiskit
• Implemented Hamiltonian simulation models of the 2D Transverse-Field Ising model on a variety of lattices and compared to the classical Ising model in terms of accuracy and time complexity
• Continued to help incoming students implement their own research projects

Directed Reading Program (DRP)

Spring 2023 - Present

Mentors: Zhixin Fan, Amir Raz, Jiwoong Park

• Studied relativistic plasma physics by running simulations using Maxwell's equations and particle-in-cell code
• Studied exact solutions to the 2D Ising Model using condensed matter field theory, specifically Wick rotations and Euclidean field theory
• Studied combinatorial Lie groups and the Young Tableaux

Quantum Optics Lab

Summer 2023

Advisor: Brian LaCour

• Worked with class 3B laser systems
• Demonstrated basic laws of quantum optics such as Malus's Law and Born's rule through physical implementation
• Quantified the entanglement achieved using our setup using concurrence and entropy of formation

Undergraduate Learning Assistant

Fall 2023 - Present

Professor: Noah Davis

• Hosted office hours and discussion sessions for students in the Quantum Computing FRI Stream
• Taught the basics of quantum computing through the IBM Quantum Experience and Qiskit
• Aided in-class discussions, graded homework, and proctored exams

Gender Matters in Physics

Spring 2023 - Spring 2024

Role: Treasurer

• Coordinated with the department for the purchase of weekly snacks and funding of outreach events such as Prospective Students Day, Longhorn Halloween, and the Partial Eclipse Celebration
• Coordinated with local businesses to raise money through profit shares

Physics Committees

Fall 2023 - Spring 2024

• Led the development of the Undergrad Physics Repository Website: https://sites.utexas.edu/physicsrepository/
• Helped facilitate testimonials with undergraduates, explained key concepts about the degree plan, and provided resources about possible career paths after undergrad
