Mechanical control of physical properties in the van der Waals ferromagnet Cr2Ge2Te6 via application of electric current
Hengdi Zhao, Yifei Ni, Bing Hu +6
Cr2Ge2Te6 is a van der Waals ferromagnet with a Curie temperature at 66 K. Here we report a swift change in the magnetic ground state upon application of small DC electric current,…
The ground state in a proximity to a possible Kitaev spin liquid: An undistorted honeycomb iridate NaxIrO3 (0.60 < x < 0.80)
Hengdi Zhao, Bing Hu, Feng Ye +3
We report results of our study of a newly synthesized honeycomb iridate NaxIrO3 (0.60 < x < 0.80). Single-crystal NaxIrO3 adopts a honeycomb lattice noticeably without distortions…
Strange electrical transport: Colossal magnetoresistance via avoiding fully polarized magnetization in ferrimagnetic insulator Mn3Si2Te6
Yifei Ni, Hengdi Zhao, Yu Zhang +3
Colossal magnetoresistance is of great fundamental and technological significance and exists mostly in the manganites and a few other materials. Here we report colossal magnetoresi…
Fortuitous partners of antiferromagnetic and Mott states in spin-orbit-coupled Sr2IrO4: A study of Sr2Ir1-xMxO4 (M=Fe or Co)
Bing Hu, Hengdi Zhao, Yu Zhang +3
Sr2IrO4 is an archetypal spin-orbit-coupled Mott insulator with an antiferromagnetic state below 240 K. Here we report results of our study on single crystals of Sr2Ir1-xFexO4 (0<x…
Quest for New Quantum States via Field-Editing Technology
Gang Cao, Hengdi Zhao, Bing Hu +4
We report new quantum states in spin-orbit-coupled single crystals that are synthesized using a game-changing technology that "field-edits" crystal structures (borrowing from the p…
Nonequilibrium Orbital Transitions via Applied Electrical Current in Calcium Ruthenate
Hengdi Zhao, Bing Hu, Feng Ye +3
Simultaneous control of structural and physical properties via applied electrical current poses a key, new research topic and technological significance. Studying the spin-orbit-co…
A Novel ground state in a new dimer iridate Ba13Ir6O30 with Ir6+(5d3) Ions
Hengdi Zhao, Feng Ye, Hao Zheng +5
We have synthesized and studied a new iridate, Ba13Ir6O30, with unusual Ir oxidation states: 2/3 Ir6+(5d3) ions and 1/3 Ir5+(5d4) ions. Its crystal structure features dimers of fac…
Dynamical properties of the Rabi model
Binglu Hu, Huili Zhou, Shujie Chen +2
We study the dynamical properties of the quantum Rabi model within a systematic expansion method. Based on the observation that the parity symmetry of the Rabi model is kept during…
Quantum fidelity for degenerate groundstates in quantum phase transitions
Yao Heng Su, Bing-Quan Hu, Sheng-Hao Li +1
Spontaneous symmetry breaking mechanism in quantum phase transitions manifests the existence of degenerate groundstates in broken symmetry phases. To detect such degenerate grounds…
Bifurcation in ground-state fidelity for a one-dimensional spin model with competing two-spin and three-spin interactions
Hong-Lei Wang, Yan-Wei Dai, Bing-Quan Hu +1
A one-dimensional quantum spin model with the competing two-spin and three-spin interactions is investigated in the context of a tensor network algorithm based on the infinite matr…
Geometric entanglement from matrix product state representations
Bing-Quan Hu, Xi-Jing Liu, Jin-Hua Liu +1
An efficient scheme to compute the geometric entanglement per lattice site for quantum many-body systems on a periodic finite-size chain is proposed in the context of a tensor netw…
Ground state fidelity in bond-alternative Ising chains with Dzyaloshinskii-Moriya interactions
Bo Li, Sam Young Cho, Hong-Lei Wang +1
A systematic analysis is performed for quantum phase transitions in a bond-alternative one-dimensional Ising model with a Dzyaloshinskii-Moriya (DM) interaction by using the fideli…
