Discovery of an odd-parity f-wave charge order in a kagome metal
Jiangchang Zheng, Caiyun Chen, Ruiqin Fu +13
The spontaneous breaking of symmetries is a cornerstone of physics, defining the phases of matter from the cosmological scale to the quantum realm. In condensed matter, electronic…
Local spectroscopy of loop current order with individual magnetic atoms
Jiangchang Zheng, Caiyun Chen, Xu Zhang +16
Hidden ordered states--characterized by order parameters that elude conventional probes--pose a fundamental challenge for their identification in quantum materials. Recent experime…
Quantum Spin Liquids in Weak Mott Insulators with a Spin-Orbit Coupling
Asimpunya Mitra, Daniel J. Schultz, Yong Baek Kim
The weak Mott insulating regime of the triangular lattice Hubbard model exhibits a rich magnetic phase diagram as a result of the ring exchange interaction in the spin Hamiltonian.…
Electric field control of a quantum spin liquid in weak Mott insulators
Daniel J. Schultz, Alexandre Khoury, Félix Desrochers +3
The triangular lattice Hubbard model at strong coupling, whose effective spin model contains both Heisenberg and ring exchange interactions, exhibits a rich phase diagram as the ra…
Complex fixed points of the non-Hermitian Kondo model in a Luttinger liquid
SangEun Han, Daniel J. Schultz, Yong Baek Kim
Non-Hermitian physics in open quantum many-body systems provides novel opportunities for the discovery of exotic quantum phenomena unexpected in Hermitian systems. A previous study…
Quantum impurity model for two-stage multipolar ordering and Fermi surface reconstruction
Daniel J. Schultz, SangEun Han, Yong Baek Kim

Non-Fermi liquid behavior and quantum criticality in cubic heavy fermion systems with non-Kramers multipolar local moments
SangEun Han, Daniel J. Schultz, Yong Baek Kim
Notable non-Fermi liquid and quantum critical behaviors are observed in rare-earth metallic systems with non-Kramers local moments supporting a number of different multipolar momen…
Non-Trivial Fixed Points and Truncated SU(4) Kondo Models in a Quasi-Quartet Multipolar Quantum Impurity Problem
Daniel J. Schultz, Adarsh S. Patri, Yong Baek Kim
The multipolar Kondo problem, wherein the quantum impurity carries higher-rank multipolar moments, has seen recent theoretical and experimental interest due to proposals of novel n…
Rise and Fall of Non-Fermi Liquid Fixed Points in Multipolar Kondo Problems
Daniel J. Schultz, Adarsh S. Patri, Yong Baek Kim
Recently it was shown that the multipolar Kondo problem, wherein a quantum impurity carrying higher-rank multipolar moments interacts with conduction electrons, leads to novel non-…
