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…
Critical theory of non-Fermi liquid fixed point in multipolar Kondo problem
Adarsh S. Patri, Yong Baek Kim
When the ground state of a localized ion is a non-Kramers doublet, such localized ions may carry multipolar moments. For example, Pr ions in a cubic environment would posses…
Distinguishing dipolar and octupolar quantum spin ices using contrasting magnetostriction signatures
Adarsh S. Patri, Masashi Hosoi, Yong Baek Kim
Recently there have been a number of experiments on CeZrO and CeSnO, suggesting that these materials host a three-dimensional quantum spin liquid with emerg…
Theory of magnetostriction for multipolar quantum spin ice in pyrochlore materials
Adarsh S. Patri, Masashi Hosoi, SungBin Lee +1
Multipolar magnetism is an emerging field of quantum materials research. The building blocks of multipolar phenomena are magnetic ions with a non-Kramers doublet, where the orbital…
Emergent non-Fermi-liquid phenomena in multipolar quantum impurity systems
Adarsh S. Patri, Ilia Khait, Yong Baek Kim
Discovery of novel spin-orbital entangled quantum ground states paves an important avenue for controllable quantum materials via unique couplings to the lattice and other external…
Unveiling Hidden Orders: Magnetostriction as a Probe of Multipolar-Ordered States
Adarsh S. Patri, Akito Sakai, SungBin Lee +3
Broken symmetries in solids involving higher order multipolar degrees of freedom are historically referred to as "hidden orders" due to the formidable task of detecting them with c…
