Magnetic field induced phenomena in Kitaev spin liquids
Shi Feng, Nandini Trivedi
Quantum spin liquids (QSLs) host a variety of fractionalized particles. In Kitaev's paradigmatic honeycomb model a spin- fractionalizes into flux due to emergen…
Spin-orbit coupling controlled two-dimensional magnetism in chromium trihalides
Inhee Lee, Jiefu Cen, Oleksandr Molchanov +7
CrX (X = Cl, Br, I) have the same crystal structure and Hamiltonian but different ligand spin-orbit coupling (SOC) constant , providing excellent material platform explori…
Emergent quantum Majorana metal from a chiral spin liquid
Penghao Zhu, Shi Feng, Kang Wang +2
We propose a mechanism to explain the emergence of an intermediate gapless spin liquid phase in the antiferromagnetic Kitaev model in an externally applied magnetic field, sandwich…
Fractionalization Signatures in the Dynamics of Quantum Spin Liquids
Kang Wang, Shi Feng, Penghao Zhu +4
We investigate the signatures of fractionalization in quantum spin liquids by studying different phases of the Kitaev honeycomb model in the presence of an out-of-plane magnetic fi…
Dimensional reduction of Kitaev spin liquid at quantum criticality
Shi Feng, Adhip Agarwala, Nandini Trivedi
We investigate the fate of the Kitaev spin liquid (KSL) under the influence of an external magnetic field in the [001] direction and upon tuning bond anisotropy of the Kitaev c…
Machine learning reveals features of spinon Fermi surface
Kevin Zhang, Shi Feng, Yuri D. Lensky +2
With rapid progress in simulation of strongly interacting quantum Hamiltonians, the challenge in characterizing unknown phases becomes a bottleneck for scientific progress. We demo…
Detection of long-range entanglement in gapped quantum spin liquids by local measurements
Shi Feng, Yanjun He, Nandini Trivedi
Topological order, reflected in long range patterns of entanglement, is quantified by the topological entanglement entropy (TEE) . We show that for gapped quantum spin liquids (…
Anyon dynamics in field-driven phases of the anisotropic Kitaev model
Shi Feng, Adhip Agarwala, Subhro Bhattacharjee +1
The Kitaev model on a honeycomb lattice with bond-dependent Ising interactions offers an exactly solvable model of a quantum spin liquid (QSL) with gapped fluxes and gapless…
Gapless to gapless phase transitions in quantum spin chains
Shi Feng, Gonzalo Alvarez, Nandini Trivedi
We investigate spin chains with bilinear-biquadratic (BLBQ) spin interactions as a function of an applied magnetic field . At the Uimin-Lai-Sutherland (ULS) critical point we fi…
Magnetic phase transitions in quantum spin-orbital liquids
Shi Feng, Niravkumar D. Patel, Panjin Kim +2
We investigate the spin and orbital correlations of a superexchange model with spin and orbital relevant for transition metal Mott insulators, using exact diagon…
