Building quantum matter, one layer at a time.
We assemble atomically thin crystals into devices, control their interfaces and surroundings, and measure the collective behavior of their electrons.
Control the system. Explore what emerges.
What makes a superconductor?
We investigate both the strength of electron pairing and its quantum phase.
Follow this question →What changes when we twist?
Our scanning van der Waals microscope controls a crystal interface during a measurement.
Follow this question →Can we shape collective behavior?
Fields and neighboring layers give us controls over the environment electrons experience.
Follow this question →From a crystal flake to a quantum experiment.
We assemble layered devices, pattern their electrodes and measure them near absolute zero. We also build instruments that let us change the experiment while it is running.
People, progress and papers.
Jamie Talmor joins the group
Jamie Talmor has joined the group as a PhD student, after a BA in physics at Oberlin College. Jamie holds a Doctoral Recruitment Award and is building our millikelvin scanning van der Waals microscope.
Eames Donovan wins an Ontario Graduate Scholarship
PhD candidate Eames Donovan has received an Ontario Graduate Scholarship. Eames studies interacting electronic states in bilayer graphene.
A second atomic force microscope
A new atomic force microscope from AFM Workshop has been running in the lab since late June. It handles everyday imaging of crystals and finished devices, which frees our Park NX7 for scanning van der Waals microscopy.

Summer researchers join the lab
Our summer research team grew in May. Elizabeth Ormsby, supported by a CQIQC summer fellowship, worked on bilayer graphene under pressure; Emma Creelman, visiting from the University of British Columbia with an NSERC Undergraduate Student Research Award, measured friction between atomically thin layers; and Anthony Kondi carried out a project through our PHY379 research course. Andrea Barbieri, already a member of the group, continued his rhombohedral graphene work with a CQIQC summer fellowship of his own.
Tianyu Liang wins an NSERC doctoral scholarship
PhD student Tianyu Liang has received an NSERC Canada Graduate Scholarship (Doctoral). Tianyu builds superconducting junctions from layered materials.
Our measurement laboratory is complete
Our measurement laboratory is complete. It houses a dilution refrigerator that reaches 7 mK and a variable-temperature cryostat, both with 12 T magnets, for measuring quantum materials at the lowest temperatures and highest fields.
Sam Paudel wins an NSERC master's scholarship
Sam Paudel holds an NSERC Canada Graduate Scholarship (Master's), which supported his first year of graduate study in the group.
Tianyu Liang joins the group
Tianyu Liang has joined the group as a PhD student with a Connaught International Scholarship, after a BSc in physics at Peking University.
