Dispersion forces between weakly disordered Van der Waals crystals
Jonas von Milczewski, John R. Tolsma
We describe a many-body theory for interlayer dispersion forces between weakly disordered atomically thin crystals and numerically investigate the role of disorder for different la…
Majorana zero modes in a quantum wire platform without Rashba spin-orbit coupling
Ömer M. Aksoy, John R. Tolsma
We propose a platform for engineering helical fermions in a hybridized double-quantum-wire setup. When our setup is proximity coupled to an -wave superconductor it can become a…
Collective modes of Dirac and Weyl semimetals in strong magnetic fields
John R. Tolsma, Fengcheng Wu, Allan H. MacDonald
Dirac and Weyl semimetals provide a new example of three-dimensional electron gases which are sensitive to strong magnetic fields. In this paper we address their collective excitat…
Orbital and spin order in oxide two-dimensional electron gases
John R. Tolsma, Marco Polini, Allan H. MacDonald
We describe a variational theory of multi-band two-dimensional electron gases that captures the interplay between electrostatic confining potentials, orbital-dependent interlayer e…
Quasiparticle Mass Enhancement and Fermi Surface Shape Modification in Oxide Two-Dimensional Electron Gases
John R. Tolsma, Alessandro Principi, Reza Asgari +2
We propose a model intended to qualitatively capture the electron-electron interaction physics of two-dimensional electron gases formed near transition-metal oxide heterojunctions…
Electronic Cooling via Interlayer Coulomb Coupling in Multilayer Epitaxial Graphene
Momchil T. Mihnev, John R. Tolsma, Charles J. Divin +7
In van der Waals bonded or rotationally disordered multilayer stacks of two-dimensional (2D) materials, the electronic states remain tightly confined within individual 2D layers. A…
Band offset and negative compressibility in graphene-MoS2 heterostructures
S. Larentis, J. R. Tolsma, B. Fallahazad +4
We use electron transport to characterize monolayer graphene - multilayer MoS2 heterostructures. Our samples show ambipolar characteristics and conductivity saturation on the elect…
One- and two-photon ionization cross sections of the laser excited 6s6p^1P_1 state of barium
John R. Tolsma, Daniel J. Haxton, Rekishu Yamazaki +2
Stimulated by a recent measurement of coherent control in photoionization of atomic barium, we have calculated one- and two-photon ionization cross sections of the aligned 6s6p^1P_…
