Spin dynamics of the spin-1 triangular lattice Heisenberg antiferromagnet KNi(SeO)
Chaebin Kim, Sathvik Nallapati, E. A. Ghioldi +6
Strong quantum fluctuations and unconventional spin dynamics are well established in the spin-1/2 triangular lattice Heisenberg antiferromagnet. However, their survival in the spin…
Magnon-Mediated Superconductivity in the Infinite- Triangular Lattice
Hantian Zhu, Yixin Zhang, Shang-Shun Zhang +2
We demonstrate that the infinite- triangular-lattice Hubbard model supports a superconducting state built from tightly bound Cooper pairs composed of two holes and one magnon ($…
Nonlinear light cone spreading of correlations in a triangular quantum magnet: a hard quantum simulation target
A. Scheie, J. Willsher, E. A. Ghioldi +6
Dynamical correlations of quantum many-body systems are typically analyzed in the momentum space and frequency basis. However, quantum simulators operate more naturally in real spa…
A resonant valence bond spin liquid in the dilute limit of doped frustrated Mott insulators
Cecilie Glittum, Antonio Å trkalj, Dharmalingam Prabhakaran +3
Ideas about resonant valence bond liquids and spin-charge separation have led to key concepts in physics such as quantum spin liquids, emergent gauge symmetries, topological order,…
Large- SU(4) Schwinger boson theory for coupled-dimer antiferromagnets
Shang-Shun Zhang, Yasuyuki Kato, E. A. Ghioldi +3
We develop a systematic large- expansion based on the Schwinger boson representation of SU(4) coherent states of dimers for the paradigmatic spin- bilayer square lattice He…
Probing Chiral Kitaev Spin Liquids via Dangling Boundary Fermions
Shang-Shun Zhang, Gábor B. Halász, Cristian D. Batista
Identifying experimental probes capable of diagnosing extreme quantum behavior is widely regarded as one of the foremost challenges in modern condensed matter physics. Here, we pro…
