Electronic confinement of surface states in a topological insulator nanowire
Ruchi Saxena, Eytan Grosfeld, Sebastian E de Graaf +4
We analyze the confinement of electronic surface states in a model of a topological insulator nanowire. Spin-momentum locking in the surface states reduces unwanted backscattering…
Implementation of single-qubit gates via parametric modulation in the Majorana transmon
Elena Lupo, Eytan Grosfeld, Eran Ginossar
We present a voltage gate-based method for controlling the Majorana transmon, using a sinusoidal modulation of the induced offset charge . Working in the transmon regime and i…
Protection of quantum information in a chain of Josephson junctions
Paul Brookes, Tikai Chang, Marzena Szymanska +3
Symmetry considerations are key towards our understanding of the fundamental laws of Nature. The presence of a symmetry implies that a physical system is invariant under specific t…
Strong to weak interacting-topological phase transition of bosons on a lattice
Amrita Ghosh, Eytan Grosfeld
We study hard-core bosons on the honeycomb lattice subjected to anisotropic nearest-neighbor hopping along with anisotropic nearest-neighbor repulsion, using a quantum Monte Carlo…
Interaction-driven phase transition in one dimensional mirror-symmetry protected topological insulator
Devendra Singh Bhakuni, Amrita Ghosh, Eytan Grosfeld
Topological crystalline insulators are phases of matter where the crystalline symmetries solely protect the topology. In this work, we explore the effect of many-body interactions…
