Stabilizing the inverted phase of a WSe$_2$/BLG/WSe$_2$ heterostructure via hydrostatic pressure

Kavli Affiliate: Srijit Goswami | First 5 Authors: Máté Kedves, Bálint Szentpéteri, Albin Márffy, Endre Tóvári, Nikos Papadopoulos | Summary: Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin–orbit interaction (SOI) induced by the proximity of transition metal dichalcogenides with large intrinsic SOI. Here, we […]

flippy: User friendly and open source framework for lipid membrane simulations

Kavli Affiliate: Timon Idema | First 5 Authors: George Dadunashvili, Timon Idema, , , | Summary: Animal cells are both encapsulated and subdivided by lipid bilayer membranes. Beyond just acting as boundaries, these membranes’ shapes influence the function of cells and their compartments. Physically, membranes are two-dimensional fluids with complex elastic behavior, which makes it […]

Aharonov-Bohm magnetism in open Fermi surfaces

Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Ady Stern, Anton Akhmerov, , | Summary: Orbital diamagnetism requires closed orbits according to the Liftshiftz-Kosevich theory. Therefore, one might expect that open Fermi surfaces do not have a diamagnetic response. Contrary to this expectation, we show that open orbits in finite systems do contribute […]

Flux-Tunable Hybridization in a Double Quantum Dot Interferometer

Kavli Affiliate: Srijit Goswami | First 5 Authors: Christian G. Prosko, Ivan Kulesh, Michael Chan, Lin Han, Di Xiao | Summary: A single electron shared between two levels threaded by a magnetic flux is an irreducibly simple quantum system in which interference is predicted to occur. We demonstrate tuning of the tunnel coupling between two […]

Practical Strategies for Enhancing the Valley Splitting in Si/SiGe Quantum Wells

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Merritt P. Losert, M. A. Eriksson, Robert Joynt, Rajib Rahman, Giordano Scappucci | Summary: Silicon/silicon-germanium heterostructures have many important advantages for hosting spin qubits. However, controlling the valley splitting (the energy splitting between the two low-lying conduction-band valleys) remains a critical challenge for ensuring qubit reliability. Broad […]
