RIXS Identification of Optical Phonon-Spin Coupling Effects in CrSBr
Jayajeewana N. Ranhili, Chamini S. Pathiraja, Brody Brogdon +10
Resonant inelastic x-ray scattering provides experimental signatures of spin-phonon coupling in CrSBr through temperature-dependent Cr -edge spectra. Low-energy excitations are…
Angle evolution of the superconducting phase diagram in twisted bilayer WSe2
Yinjie Guo, John Cenker, Ammon Fischer +13
Recent observations of superconductivity in twisted bilayer WSe have extended the family of moiré superconductors beyond twisted graphene. In WSe two different twist angles…
Mapping the moiré potential in multi-layer rhombohedral graphene
Eric Seewald, Sanat Ghosh, Nishchhal Verma +11
Rhombohedral graphene (rG) aligned with hexagonal boron nitride (hBN) has been shown to host flat bands that stabilize various strongly correlated quantum phases, including Mott in…
Engineering robust strain transmission in van der Waals heterostructure devices
John Cenker, Jordan Fonseca, Mai Nguyen +8
Atomically thin van der Waals materials provide a highly tunable platform for exploring emergent quantum phenomena in solid state systems. Due to their remarkable mechanical streng…
Exciton Dressing by Extreme Nonlinear Magnons in a Layered Semiconductor
Geoffrey M. Diederich, Mai Nguyen, John Cenker +9

Continuously tunable uniaxial strain control of van der Waals heterostructure devices
Zhaoyu Liu, Xuetao Ma, John Cenker +13
Uniaxial strain has been widely used as a powerful tool for investigating and controlling the properties of quantum materials. However, existing strain techniques have so far mostl…
Strain Tuning Three-state Potts Nematicity in a Correlated Antiferromagnet
Kyle Hwangbo, Elliott Rosenberg, John Cenker +5
Electronic nematicity, a state in which rotational symmetry is spontaneously broken, has become a familiar characteristic of many strongly correlated materials. One widely studied…
Strain-programmable van der Waals magnetic tunnel junctions
John Cenker, Dmitry Ovchinnikov, Harvey Yang +12
The magnetic tunnel junction (MTJ) is a backbone device for spintronics. Realizing next generation energy efficient MTJs will require operating mechanisms beyond the standard means…
Tunable Exciton-Hybridized Magnon Interactions in a Layered Semiconductor
Geoffrey M. Diederich, John Cenker, Yafei Ren +8
The interaction between distinct excitations in solids is of both fundamental interest and technological importance. One example of such interactions is coupling between an exciton…
Exciton-Coupled Coherent Magnons in a 2D Semiconductor
Youn Jue Bae, Jue Wang, Allen Scheie +13
Two-dimensional (2D) magnetic semiconductors feature both tightly-bound excitons with large oscillator strength and potentially long-lived coherent magnons due to the presence of b…
Evidence for equilibrium excitons and exciton condensation in monolayer WTe2
Bosong Sun, Wenjin Zhao, Tauno Palomaki +14
A single monolayer of the layered semimetal WTe2 behaves as a two-dimensional topological insulator, with helical conducting edge modes surrounding a bulk state that becomes insula…
Interlayer Electronic Coupling on Demand in a 2D Magnetic Semiconductor
Nathan P. Wilson, Kihong Lee, John Cenker +10
When monolayers of two-dimensional (2D) materials are stacked into van der Waals structures, interlayer electronic coupling can introduce entirely new properties, as exemplified by…
