Machine learning predictions for local electronic properties of disordered correlated electron systems
Yi-Hsuan Liu, Sheng Zhang, Puhan Zhang +2
We present a scalable machine learning (ML) model to predict local electronic properties such as on-site electron number and double occupation for disordered correlated electron sy…
Enhanced quantum oscillations in Kondo insulators
Yen-Wen Lu, Po-Hao Chou, Chung-Hou Chung +2
Quantum oscillations have long been regarded as the manifestation of the Fermi surface in metals. However, they were recently observed in Kondo insulators. We examine the Kondo scr…
Slave-rotor theory on magic-angle twisted bilayer graphene
Shin-Ming Huang, Yi-Ping Huang, Ting-Kuo Lee
We investigate the correlated electrons in the magic-angle twisted bilayer graphene by using the slave-rotor mean-field theory. Owing to the extended figure of Wannier orbitals, we…
Revisit of Antiferromagnetism in Hubbard Model by A Cluster Slave-Spin Method
Wei-Cheng Lee, Ting-Kuo Lee
The cluster slave-spin method is introduced to systematically investigate the solutions of the Hubbard model including the symmetry-broken phases. In this method, the electron oper…
Emergence of fermionic finite-temperature critical point in a Kondo lattice
Po-Hao Chou, Liang-Jun Zhai, Chung-Hou Chung +2
The underlying Dirac point is central to the profound physics manifested in a wide class of materials. However, it is often difficult to drive a system with Dirac points across the…
Impurity Scattering Effects in STM Studies of High-T_c Superconductors
Noboru Fukushima, Chung-Pin Chou, Ting Kuo Lee
Recent STM measurements have observed many inhomogeneous patterns of the local density of states on the surface of high-T_c cuprates. As a first step to study such disordered stron…
