Competing Laughlin state and Wigner crystal in bilayer graphene

We study the fractional quantum Hall effect in the central Landau level of bilayer graphene. By tuning the external applied magnetic field and the electric bias between the two layers one can access a regime where there is a degeneracy between Landau

Spin and valley ordering of fractional quantum Hall states in monolayer graphene

Autor: Thierry Jolicoeur, Ngoc Duc Le

Publikováno v: Physical Review B
Physical Review B, 2022, 105, pp.075203. ⟨10.1103/PhysRevB.105.075203⟩

We study spin and valley ordering in the quantum Hall fractions in monolayer graphene at Landau level filling factors $\nu_G=-2+n/3$ $(n=2,4,5)$. We use exact diagonalizations on the spherical as well as toroidal geometry by taking into account the e

Unconventional Zn parton states at ν=7/3 : Role of finite width

Autor: Ajit C. Balram, Tongzhou Zhao, W. N. Faugno, Jainendra K. Jain, Thierry Jolicoeur

Publikováno v: Physical Review B. 103

A recent work [Balram, Jain, and Barkeshli, Phys. Rev. Res. 2, 013349 (2020)] has suggested that an unconventional state describing ${\mathbb{Z}}_{n}$ superconductivity of composite bosons, which supports excitations with charge $1/(3n)$ of the elect

Bubble phase at ν= 13 for spinless hollow-core interaction

Autor: Thierry Jolicoeur, Takahiro Mizusaki, Grégoire Misguich

Publikováno v: Physical Review B. 102

We investigate fractional quantum Hall states for model interactions restricted to a repulsive hard core. When the hard core excludes relative angular momentum $m=1$ between spinless electrons the ground state at Landau level filling factor $\ensurem

The nature of the state at low Landau-level filling factors has been a longstanding puzzle in the field of the fractional quantum Hall effect. While theoretical calculations suggest that a crystal is favored at filling factors $\nu\lesssim 1/6$, expe

Publikováno v: Physical Review X, Vol 5, Iss 2, p 021004 (2015)

Interesting non-Abelian states, e.g., the Moore-Read Pfaffian and the anti-Pfaffian, offer candidate descriptions of the ν=5/2 fractional quantum Hall state. But, the significant controversy surrounding the nature of the ν=5/2 state has been hamper

Quantum Hall skyrmions at ν = 0 , ± 1 in monolayer graphene

Physical Review B: Condensed Matter and Materials Physics (1998-2015), American Physical Society, 2019, 100 (11), ⟨10.1103/PhysRevB.100.115422⟩

Monolayer graphene under a strong perpendicular field exhibit quantum Hall ferromagnetism with spontaneously broken spin and valley symmetry. The approximate SU(4) spin/valley symmetry is broken by small lattice scale effects in the central Landau le
