Global phase diagram of charge-neutral graphene in the quantum Hall regime for generic interactions

Suman Jyoti De et al.

Summary: Monolayer graphene at charge neutrality in a quantizing magnetic field is a quantum Hall ferromagnet with various possible ground states. Recent studies have shown that a phase with coexisting canted antiferromagnetic and Kekulé order exists in the phase diagram corresponding to real samples. In this paper, the complete phase diagram of v=0 graphene in the Hartree-Fock approximation is presented, considering generic symmetry-allowed interactions and assuming translation-invariant ground states. The physical signatures of the different states are also discussed.

Competing spin-valley entangled and broken symmetry states in the N=1 Landau level of graphene

Nikolaos Stefanidis et al.

Summary: In this paper, a model is developed to describe the nature of states in the quantum Hall regime of graphene in higher Landau levels. The model includes both pure 8-function interactions and some of its derivatives. New ground states, including entangled spin and valley degrees of freedom, are found in contrast to the N = 0 Landau level. A new phase combining characteristics of a valence-bond solid and an antiferromagnet is also discovered at half-filling. The estimation of model parameters based on recent compressibility experiments is discussed.

Visualizing broken symmetry and topological defects in a quantum Hall ferromagnet

Xiaomeng Liu et al.

Summary: The interaction between electrons in graphene under high magnetic fields leads to the formation of various quantum Hall ferromagnetic (QHFM) phases with broken spin or valley symmetry. Using scanning tunneling spectroscopy (STS), we were able to visualize atomic-scale electronic wave functions and observe valley ordering in QHFM phases, as well as spectral features of fractional quantum Hall phases in graphene. The results provide insights into the electronic properties of materials and their topological excitations.

Imaging tunable quantum Hall broken-symmetry orders in graphene

Alexis Coissard et al.

Summary: In this study, three distinct broken-symmetry phases in graphene were directly imaged using scanning tunnelling spectroscopy. It was found that graphene exhibits different lattice-scale orders under different conditions, deviating from current theoretical predictions. These findings are important for uncovering correlated phases of matter in other quantum materials.

Coexistence of Canted Antiferromagnetism and Bond Order in ν=0 Graphene

Ankur Das et al.

Summary: Motivated by experiments on graphene in the quantum Hall regime, this study revisits the phase diagram of a single sheet of graphene at charge neutrality and presents the finding of a coexistence region of magnetic and bond orders. This result provides a possible explanation for experimental observations on the quantum Hall effect in graphene.

Valley Isospin Controlled Fractional Quantum Hall States in Bilayer Graphene

Ke Huang et al.

Summary: In this study, we investigate the control over valley isospin degrees of freedom in bilayer graphene using a perpendicular electric field. We observe a new even-denominator fractional quantum Hall state at filling factor v = 5/2 and the appearance of predicted daughter states and anti-Pfaffian states. These findings pave the way for manipulating valley isospin in bilayer graphene to engineer exotic topological orders and quantum information processes.

Experimental Determination of the Energy per Particle in Partially Filled Landau Levels

Fangyuan Yang et al.

Summary: The experimental technique allows for high sensitivity measurement of the chemical potential in atomically thin layered materials. Results show exceptional agreement with numerical calculations in the N = 0 Landau level, while suggesting the importance of valley anisotropic interactions and possible presence of valley-textured electron solids near odd filling in the N = 1 Landau level.

Gapless Spin Wave Transport through a Quantum Canted Antiferromagnet

Hailong Fu et al.

Summary: In this work, a new experimental method was demonstrated to successfully detect gapless, linearly dispersed spin wave excitations in bilayer graphene, providing direct evidence for a predicted antiferromagnetic order. The spin wave mode propagates at a high velocity and maintains phase coherence over a significant distance, consistent with hydrodynamic theory. These findings lay the groundwork for exploring spin superfluidity and potentially engineering magnonic devices in high-quality materials.

SU(4) spin waves in the ν = ±1 quantum Hall ferromagnet in graphene

Jonathan Atteia et al.

Summary: The study of generalized spin waves in graphene under a strong magnetic field with Landau-level filling factor nu = +/- 1 reveals a specific SU(4) quantum Hall ferromagnet ground state with full spin and valley polarization. The breaking of symmetry affects the nature of the ground state and spin-valley polarization, reflected in the generalized spin-wave spectrum. Besides pure spin waves, there are also valley-pseudospin waves and exotic entanglement waves with mixed spin-valley character.
