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…
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…
Low-energy edge signatures of the Kitaev spin liquid
Shang-Shun Zhang, Cristian D. Batista, Gábor B. Halász
Recent experimental work indicates that the Kitaev spin liquid may be realizable close to zero magnetic field in exfoliated -RuCl flakes, thus providing a more versatile set…
Electronic Raman scattering of antiferromagnetic excitonic insulators
Hidemaro Suwa, Shang-Shun Zhang, Cristian D. Batista
The excitonic insulator, a quantum mechanical state arising from exciton condensation, was proposed theoretically many years ago but has yet to be experimentally confirmed. The dis…
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…
A resonant valence bond spin liquid in the dilute limit of doped frustrated Mott insulators
Cecilie Glittum, Antonio Štrkalj, 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,…
Classical dynamics of the antiferromagnetic Heisenberg spin ladder
David A. Dahlbom, Jinu Thomas, Steven Johnston +2
We employ a classical limit grounded in SU(4) coherent states to investigate the temperature-dependent dynamical spin structure factor of the ladder consisting of weakly…
Quantum to classical crossover in generalized spin systems -- the temperature-dependent spin dynamics of FeI
D. Dahlbom, D. Brooks, M. S. Wilson +9
Simulating quantum spin systems at finite temperatures is an open challenge in many-body physics. This work studies the temperature-dependent spin dynamics of a pivotal compound, F…
Large- limit of the large- theory for the triangular antiferromagnet
Shang-Shun Zhang, E. A. Ghioldi, Yoshitomo Kamiya +3
Large- and large- theories (spin value and spinor component number ) are complementary, and sometimes conflicting, approaches to quantum magnetism. While large- spi…
