Neural Polaron: Learning Quasiparticle Operators in Quantum Many-Body Systems
Shang-Shun Zhang
Understanding dynamical properties of quantum many-body systems remains a central challenge because excitations generally require information beyond a ground-state wave function. H…
Superconductivity and fractionalized magnetic excitations in CeCoIn5
Pyeongjae Park, Shang-Shun Zhang, Pietro M. Bonetti +8
Recent experiments on CeCoIn5 -- a prototypical d-wave superconductor -- indicate that its normal state lies near an unconventional quantum critical point (QCP). One intriguing hyp…
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 ($…
Intrinsic quantum disorder in Yb2Ti2O7 and the quantum S=1/2 pyrochlore phase diagram
Shang-Shun Zhang, Anish Bhardwaj, S. M. Koohpayeh +4
We present an experimental and theoretical study of the anisotropic pyrochlore phase diagram. Inelastic field-dependent neutron scattering on YbTiO shows intrinsic broa…
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…
Spin dynamics of triple-Q magnetic orderings in a triangular lattice: Implications for multi-Q orderings in general two-dimensional lattices
Pyeongjae Park, Woonghee Cho, Chaebin Kim +7
Multi-Q magnetic structures on two-dimensional (2D) lattices provide a key route to realizing topological physics in 2D magnetism. A major experimental challenge is to unambiguousl…
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…
