Spontaneous Layer Polarization and Conducting Domain Walls in the Quantum Hall Regime of Bilayer Graphene
Kusum Dhochak, Efrat Shimshoni, Erez Berg
Bilayer graphene subjected to perpendicular magnetic and electric fields displays a subtle competition between different symmetry broken phases, resulting from an interplay between…
Collective Edge Modes near the onset of a graphene quantum spin Hall state
Ganpathy Murthy, Efrat Shimshoni, H. A. Fertig
Graphene subject to a strong, tilted magnetic field exhibits an insulator-metal transition tunable by tilt-angle, attributed to the transition from a canted antiferromagnetic (CAF)…
Plaquette Order in a Dimerized Frustrated Spin-Ladder
Ofer Shlagman, Efrat Shimshoni
We study the effect of spin-Peierls instability on the phase-diagram of a frustrated antiferromagnetic spin-1/2 ladder, with weak transverse and diagonal rung coupling. Our analysi…
Helical quantum Hall Edge modes in bilayer graphene: a realization of quantum spin-ladders
Victoria Mazo, Chia-Wei Huang, Efrat Shimshoni +2
The rich phase diagram of quantum spin-ladder systems has attracted much attention in the theoretical literature. The progress in experimental realisations of this fascinating phys…
From classical to quantum criticality
Daniel Podolsky, Efrat Shimshoni, Pietro Silvi +4
We study the crossover from classical to quantum phase transitions at zero temperature within the framework of theory. The classical transition at zero temperature can be des…
