A Scalable Configuration-Interaction Impurity Solver via Active Learning
Jeongmoo Lee, Ara Go
Finite-Hamiltonian impurity solvers provide direct real-frequency spectra and a natural route to enlarged impurity Hamiltonians, but their applicability is limited by the rapid Hil…
Data-Driven Bath Fitting for Hamiltonian-Diagonalization Dynamical Mean-Field Theory
Taeung Kim, Jeongmoo Lee, Ara Go
We propose a machine-learning-based initialization method to overcome the nonlinear bath-fitting bottleneck in Hamiltonian-diagonalization-based dynamical mean-field theory (HD-DMF…
High-resolution neutron diffraction determination of noncollinear antiferromagnetic order in the honeycomb magnetoelectric FeNbO
Raktim Datta, Kapil Kumar, Dong Gun Oh +7
Magnetoelectric systems offer potential for device applications exploiting coupled states between electric and magnetic properties. Among magnetoelectric materials, \FNO has attrac…
Intertwined Orders in a Quantum-Entangled Metal
Junyoung Kwon, Jaehwon Kim, Gwansuk Oh +18
Entanglement underpins quantum information processing and computing, yet its experimental quantification in complex, many-body condensed matter systems remains a considerable chall…
