Developing an Interactive Tutorial on a Mach-Zehnder Interferometer with Single Photons
Chandralekha Singh, Emily Marshman
We are developing a Quantum Interactive Learning Tutorial (QuILT) on a Mach-Zehnder Interferometer with single photons to expose upper-level students in quantum mechanics courses t…
Developing an Interactive Tutorial on a Quantum Eraser
Emily Marshman, Chandralekha Singh
We are developing a quantum interactive learning tutorial (QuILT) on a quantum eraser for students in upperlevel quantum mechanics. The QuILT exposes students to contemporary topic…
Investigating Student Difficulties with Time dependence of Expectation Values in Quantum Mechanics
Emily Marshman, Chandralekha Singh
Quantum mechanics is challenging even for advanced undergraduate and graduate students. In the Schrödinger representation, the wave function evolves in time according to the time d…
Investigating Student Difficulties with Dirac Notation
Chandralekha Singh, Emily Marshman
Quantum mechanics is challenging even for advanced undergraduate and graduate students. Dirac notation is a convenient notation used extensively in quantum mechanics. We have been…
Analogous Patterns of Student Reasoning Difficulties in Introductory Physics and Upper-Level Quantum Mechanics
Chandralekha Singh, Emily Marshman
Very little is known about how the nature of expertise in introductory and advanced courses compares in knowledge-rich domains such as physics. We develop a framework to compare th…
Student difficulties with quantum states while translating state vectors in Dirac notation to wave functions in position and momentum representations
Emily Marshman, Chandralekha Singh
We administered written free-response and multiple-choice questions and conducted individual interviews to investigate the difficulties that upper-level undergraduate and graduate…
