Magic behavior of low-dimensional nanostructures
Virtual eventLike in a magic trick, atomically thin layers of specific materials can be mixed and stacked in a well-defined way. Due to the inter-layer interaction and charge transfer, the heterostructure may exhibit sometimes unexpected behavior. This occurs in the case of elemental boron, which is notorious for a large number of stable allotropes not only in 3D bulk, but also in 2D.

CM Seminar: Controlling Emergent Behavior in Quantum Matter from a Theory Perspective
Virtual eventSpeaker: Prineha Narang, Assistant Professor at Harvard University My group’s research focuses on how quantum matter behaves, particularly away from equilibrium, and how we can harness emergent effects in these systems. In this context, I will focus on our newly introduced approaches to describe excited-states in quantum matter, including electron-electron and electron-phonon interactions beyond […]
Jason Alicea: Internally engineered Majorana modes in twisted bilayer graphene
Virtual eventAbstract: Twisted bilayer graphene (TBG) realizes an exquisitely tunable, strongly interacting system featuring superconductivity and various correlated insulating states. In this talk I will introduce gate-defined wires in TBG as an enticing platform for Majorana-based fault-tolerant qubits. Our proposal notably relies on “internally” generated superconductivity in TBG – as opposed to “external” superconducting proximity effects […]
CM Seminar – Benjamin Frandsen
Talk title: From Quantum Magnets to Magnetic Thermoelectrics: Short-Range Spin Correlations and the Secrets They Keep Speaker: Benjamin Frandsen, Brigham Young University Abstract: Short-range magnetic correlations have been increasingly recognized in recent years for their importance in contexts as widely varied as geometrically frustrated magnetism and functional magnetocaloric materials. Neutron scattering provides experimental access to […]

Virtual eventhttps://ubc.zoom.us/j/66879995529?pwd=dHpQb25LSGVZK3ozY243em5tenRWQT09 Meeting ID: 668 7999 5529 Passcode: 113399 Abstract: The addition of non-unitary ingredients to many-body quantum dynamics has led to a series of exciting developments in recent years, including new out-of-equilibrium entanglement phases and phase transitions enabled by quantum measurements. I will present recent work in which we show that a duality transformation between space and time on one […]

One of the most exotic phenomena in […]
Abhay Pasupathy: Recent progress in moiré materials
Virtual eventhttps://ubc.zoom.us/j/66879995529?pwd=dHpQb25LSGVZK3ozY243em5tenRWQT09 Meeting ID: 668 7999 5529 Passcode: 113399 Speaker: Abhay Pasupathy, Columbia University Abstract: I will discuss two recent sets of experiments from my group on moiré materials. In the first experiment, I will discuss transport experiments on twisted bilayers of the monolayer semiconductor WSe2 (Wang et al, Nature Materials 19, 861 (2020) and […]
Cory R. Dean: Towards realizing twistronics on demand
Virtual eventTitle: Towards realizing twistronics on demand Speaker: Cory R. Dean, Department of Physics, Columbia University Abstract: The ability to isolate atomically thin crystals, such as graphene, boron nitride, and the transition metal dichalcogenides, and then mechanically layer them to form new heterostructures has driven a recent revolution in materials design. These layered structures are held […]
