Magnetism and charge density wave order in kagome FeGe

Xiaokun Teng et al.

Summary: Electron correlations in quantum materials can lead to emergent orders, such as the topological states found in kagome lattice materials. These emergent orders are a result of the specific electronic band structure associated with the kagome lattice geometry. Various correlated electronic phases, including magnetism and superconductivity, have been discovered in kagome lattice materials. In this study, the authors observe all three electronic signatures of the kagome lattice in FeGe using angle-resolved photoemission spectroscopy and provide evidence for the interplay between magnetism and charge order in this material.

Emergent Glassy Behavior in a Kagome Rydberg Atom Array

Zheng Yan et al.

Summary: We perform large-scale quantum Monte Carlo simulations on a realistic Hamiltonian of kagome-lattice Rydberg atom arrays and analyze their static and dynamic properties. We find emergent glassy behavior in a region of parameter space between two valence bond solid phases. The extent and phase transitions of this glassy phase as well as its slow time dynamics and experimental considerations for its detection are discussed. Our proposal opens up a new route to studying real-time glassy phenomena and highlights the potential for quantum simulation of distinct phases of quantum matter.

Frustration- and doping-induced magnetism in a Fermi-Hubbard simulator

Muqing Xu et al.

Summary: Geometrical frustration in strongly correlated systems can lead to the emergence of novel ordered states and magnetic phases, such as quantum spin liquids. This study investigates the effects of frustration and doping on the local spin order in a controllable Hubbard model. The results show that frustration reduces the range of magnetic correlations and induces a transition from a collinear Neel antiferromagnet to a short-range correlated 120 degrees spiral phase. The triangular lattice exhibits enhanced antiferromagnetic correlations on the hole-doped side and a reversal to ferromagnetic correlations at high particle dopings.

Observation of flat band, Dirac nodal lines and topological surface states in Kagome superconductor CsTi3Bi5

Jiangang Yang et al.

Summary: In this study, the electronic structure of the newly discovered kagome superconductor CsTi3Bi5 is investigated using laser-based angle-resolved photoemission spectroscopy combined with density functional theory calculations. A flat band derived from the destructive interference of Bloch wave functions within the kagome lattice is observed. Type-II and type-III Dirac nodal lines are identified, as well as Z(2) nontrivial topological surface states induced by band inversion mediated by strong spin-orbit coupling.

Charge order and superconductivity in kagome materials

Titus Neupert et al.

Summary: Superconductivity and ordered states have been observed in a family of kagome materials, with lattice geometry, topological electron behavior, and competition between ground states playing key roles in determining material properties. The compounds KV3Sb5, CsV3Sb5, and RbV3Sb5 exhibit a kagome net of vanadium atoms, showing superconductivity at low temperatures and unusual charge order at high temperatures, connecting to the underlying topological nature of the band structure. This highlights the importance of these discoveries in the context of wider research efforts in topological physics and superconductivity, while also discussing open problems in this field.

Topological kagome magnets and superconductors

Jia-Xin Yin et al.

Summary: A kagome lattice naturally exhibits Dirac fermions, flat bands, and van Hove singularities, which enable the realization of topological kagome magnets and superconductors with exotic properties. Recent studies have shown that the quantum interactions between geometry, topology, spin, and correlation give rise to rich emergent phenomena in kagome materials. These developments advance the frontier of topological quantum matter and bridge topological quantum physics and correlated many-body physics.

Dynamical Preparation of Quantum Spin Liquids in Rydberg Atom Arrays

Giuliano Giudici et al.

Summary: Recent experiments demonstrate the onset of a topological spin liquid using a programmable quantum simulator based on Rydberg atom arrays. By preparing out-of-equilibrium states using a quasiadiabatic state preparation protocol, robust signatures of topological order emerge. The state preparation protocol can be optimized to target the fixed point of the topological phase, and a two-parameter variational manifold of tensor network states accurately describes the many-body dynamics of the preparation process.

Scaling advantage over path-integral Monte Carlo in quantum simulation of geometrically frustrated magnets

Andrew D. King et al.

Summary: Experimental observations show that quantum simulation has a dynamic advantage over classical methods in simulations of geometrically frustrated magnets. This advantage increases with system size and inverse temperature, achieving a million-fold speedup over efficient CPU implementations. The study provides important evidence that near-term quantum devices can accelerate computational tasks of practical relevance.
