Coexisting ferromagnetic-antiferromagnetic state in twisted bilayer CrI3

Yang Xu et al.

Summary: Research on Moire engineering in van der Waals magnetic materials has shown the potential to create new magnetic ground states, with experiments showcasing the coexistence of ferromagnetic and antiferromagnetic states in small-twist-angle CrI3 bilayers, which can be controlled by electric gating.

Conformality and self-duality of Nf=2 QED3

Zhijin Li

Summary: We study the infrared (IR) phase of a three-dimensional quantum electrodynamics (QED(3)) coupled to two-component Dirac fermions with N-f = 2 flavors, which has been a subject of controversy for a long time. Our focus is on the four-point correlator of monopole operators that have a unit topological charge of U(1)(t). By analyzing the O(4) -> SU(2)(f) x U(1)(t) branching rules based on an O(4) symmetric positive structure in the monopole four-point crossing equations, we use the conformal bootstrap method to derive nonperturbative constraints on the conformal field theory (CFT) data and test the conformality and self-duality of N-f = 2 QED(3). Specifically, we find that the CFT data obtained from previous lattice simulations can be ruled out when irrelevant assumptions are introduced in the spectrum, indicating that the IR phase of N-f = 2 QED(3) is not conformal.

Bootstrapping Nf=4 conformal QED3

Soner Albayrak et al.

Summary: We present the results of a conformal bootstrap study on the presumed unitary IR fixed point of quantum electrodynamics in three dimensions coupled to Nf = 4 two-component Dirac fermions. The study finds that the scaling dimensions of the fermion bilinear r and the monopole M1/2 are constrained into a closed island, consistent with 1/Nf perturbative results.

Direct visualization of magnetic domains and moire magnetism in twisted 2D magnets

Tiancheng Song et al.

Summary: By studying the magnetic properties of twisted CrI3 materials, emerging magnetic textures and periodic patterns were discovered, confirming the existence of moire superlattices and exploring the coexistence of antiferromagnetic and ferromagnetic domains at different layer thicknesses. This highlights magnetic moire superlattices as a potential platform for exploring nanomagnetism.

Moire Skyrmions and Chiral Magnetic Phases in Twisted CrX3 (X = I, Br, and Cl) Bilayers

Muhammad Akram et al.

Summary: We present a comprehensive theory of magnetic phases in twisted bilayer chromium trihalides, showing that a wide range of noncollinear magnetic phases can be stabilized as a function of twist angle and interactions. Our results provide an interpretation for recent observations of noncollinear magnetic phases in twisted bilayer CrI3 and demonstrate the possibility of engineering further nontrivial magnetic ground states in twisted bilayer chromium trihalides.

Heterobilayer moire magnets: Moire skyrmions and commensurate-incommensurate transitions

Kasra Hejazi et al.

Summary: The study focuses on untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, particularly looking at the Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. A continuum low-energy field theory is used to develop a phase diagram based on interlayer exchange and Dzyaloshinskii-Moriya interactions, combining perturbative and strong coupling analyses with numerical simulations. Various moire-periodic commensurate phases are observed, with a special skyrmion lattice phase where each moire unit-cell hosts one skyrmion.

Magic continuum in a twisted bilayer square lattice with staggered flux

Zhu-Xi Luo et al.

Summary: In this study, a general continuum model for a bilayer system of staggered-flux square lattices was derived, and the band structure of the twisted bilayer staggered-flux square lattice was investigated. It was found that the band structure exhibits magic continuum characteristics, showing an exponential reduction of the Dirac velocity and bandwidths in a large parameter regime, and effectively describing a massless Dirac fermion. Additionally, an intuitive argument was provided for the emergence of flattened bands near half filling in the magic continuum, with an estimation of the large number of associated nearly zero-energy states.

Skyrmions in twisted van der Waals magnets

Muhammad Akram et al.

Summary: In this study, it is shown that magnetic skyrmions can be stabilized in twisted moire superlattices without an external magnetic field through the Dzyaloshinskii-Moriya interaction. The presence of a skyrmion crystal phase requires a matching of length scales between the moire periodicity and the skyrmions. Skyrmions in moire superlattices exhibit enhanced stability for the easy-axis anisotropy, making them potentially crucial for realizing skyrmions in van der Waals magnets with easy-axis anisotropy.

Magnetization textures in twisted bilayer CrX3 (X=Br, I)

Feiping Xiao et al.

Summary: The study reveals that twisted bilayer magnets form periodic magnetization domains in a long-period moire pattern, allowing for the construction of magnetization textures with different topological numbers. An external magnetic field can compete with interlayer magnetic interaction to tune the magnetization textures.
