Atomic displacements drive flat band formation and lateral electron and hole separation in near-60 degree twisted MoSe2/WSe2 bilayers
Madeleine Phillips, C. Stephen Hellberg
Transition metal dichalcogenide (TMD) bilayers with an interlayer twist exhibit a moire super-period, whose effects can manifest in both structural and electronic properties. Atomi…
Cascaded variational quantum eigensolver algorithm
Daniel Gunlycke, C. Stephen Hellberg, John P. T. Stenger
We present a cascaded variational quantum eigensolver algorithm that only requires the execution of a set of quantum circuits once rather than at every iteration during the paramet…
Expanding variational quantum eigensolvers to larger systems by dividing the calculations between classical and quantum hardware
John P. T. Stenger, Daniel Gunlycke, C. Stephen Hellberg
We present a hybrid classical/quantum algorithm for efficiently solving the eigenvalue problem of many-particle Hamiltonians on quantum computers with limited resources by splittin…
Stacking-Dependent Optical Properties in Bilayer WSe2
Kathleen M. McCreary, Madeleine Phillips, Hsun-Jen Chuang +4
The twist angle between the monolayers in van der Waals heterostructures provides a new degree of freedom in tuning material properties. We compare the optical properties of WSe2 h…
Theory of Superconductivity at the LaAlO3/SrTiO3 heterointerface: Electron pairing mediated by deformation of ferroelastic domain walls
David Pekker, C. Stephen Hellberg, Jeremy Levy
SrTiO is a superconducting semiconductor with a pairing mechanism that is not well understood. SrTiO undergoes a ferroelastic transition at 105 K, leading to the forma…
Atomic reconstruction and moiré patterns in transition metal dichalcogenide van der Waals heterostructures
Matthew R. Rosenberger, Hsun-Jen Chuang, Madeleine Phillips +5
Van der Waals layered materials, such as transition metal dichalcogenides (TMDs), are an exciting class of materials with weak interlayer bonding which enables one to create van de…
