Bounds on Bose-Einstein Condensation of Higgs modes in a Superconductor
Z. E. Krix, Daniel Loss
Collective modes in a superconductor correspond to fluctuations in the amplitude (Higgs mode) or the phase (Goldstone mode) of the order parameter. Starting from the BCS Hamiltonia…
Screening of the band gap in electrically biased bilayer graphene: From Hartree to Hartree-Fock
Jack N. Engdahl, Zeb E. Krix, Oleg P. Sushkov
It is well known that a direct band gap may be opened in bilayer graphene via the application of a perpendicular electric field (bias). The bias and the chemical potential are cont…
Quantum magnetic oscillations in the absence of closed electron trajectories
Z. E. Krix, O. A. Tkachenko, V. A. Tkachenko +4
Quantum magnetic oscillations in crystals are typically understood in terms of Bohr-Sommerfeld quantisation, the frequency of oscillation is given by the area of a closed electron…
Formation of artificial Fermi surfaces with a triangular superlattice on a conventional two dimensional electron gas
Daisy Q. Wang, Zeb Krix, Oleg P. Sushkov +4
In nearly free electron theory the imposition of a periodic electrostatic potential on free electrons creates the bandstructure of a material, determined by the crystal lattice spa…
Artificial electrostatic crystals: a new platform for creating correlated quantum states
Daisy Q. Wang, Zeb Krix, Olga A. Tkachenko +7
The electronic properties of solids are determined by the crystal structure and interactions between electrons, giving rise to a variety of collective phenomena including supercond…
Patterned bilayer graphene as a tunable, strongly correlated system
Z. E. Krix, O. P. Sushkov
Recent observations of superconductivity in Moire graphene have lead to an intense interest in that system, with subsequent studies revealing a more complex phase diagram including…
Correlated physics in an artificial triangular anti-dot lattice
Z. E. Krix, H. D. Scammell, O. P. Sushkov
This work considers a two-dimensional artificial triangular anti-dot lattice (TAL); a semiconductor based artificial crystal hosting Dirac cones, flat bands and Fermi surface nesti…
Artificial Graphene in a Strong Magnetic Field: Bulk Current Distribution and Quantum Phase Transitions
Zeb E. Krix, Oleg P. Sushkov
We present calculations of the equilibrium current density and Chern numbers for a 2DEG in a periodic potential with infinite strip geometry and a perpendicular magnetic field. We…
