True decoherence-free-subspace derived from a semiconductor double quantum dot Heisenberg spin-trimer
Wonjin Jang, Jehyun Kim, Jaemin Park +6
Spins in solid systems can inherently serve as qubits for quantum simulation or quantum information processing. Spin qubits are usually prone to environmental magnetic field fluctu…
Wigner-molecularization-enabled dynamic nuclear field programming
Wonjin Jang, Jehyun Kim, Jaemin Park +8
Multielectron semiconductor quantum dots (QDs) provide a novel platform to study the role of Coulomb correlations in finite quantum systems and their impact on many-body energy spe…
Approaching ideal visibility in singlet-triplet qubit operations using energy-selective tunneling-based Hamiltonian estimation
Jehyun Kim, Jonginn Yun, Wonjin Jang +9
We report energy selective tunneling readout-based Hamiltonian parameter estimation of a two-electron spin qubit in a GaAs quantum dot array. Optimization of readout fidelity enabl…
Slow oxidation of magnetite nanoparticles elucidates the limits of the Verwey transition
Taehun Kim, Sangwoo Sim, Sumin Lim +8
Magnetite (Fe3O4) is of fundamental importance as the original magnetic material and also for the Verwey transition near T_V = 125 K, below which a complex lattice distortion and e…
Sizeable suppression of thermal Hall effect upon isotopic substitution in strontium titanate
Sangwoo Sim, Heejun Yang, Ha-Leem Kim +4
We report measurements of the thermal Hall effect in single crystals of both pristine and isotopically substituted strontium titanate. We discovered a two orders of magnitude diffe…
Kagome van-der-Waals Pd3P2S8 with flat band
Seunghyun Park, Soonmin Kang, Haeri Kim +13
With the advanced investigations into low-dimensional systems, it has become essential to find materials having interesting lattices that can be exfoliated down to monolayer. One p…
