Conformally invariant charge fluctuations in a strange metal
Xuefei Guo, Jin Chen, Farzaneh Hoveyda-Marashi +11
The strange metal is a peculiar phase of matter in which the electron scattering rate, , which determines the electrical resistance, is universal across a…
Phase transitions in the presence of fluctuating charge-density wave in two-dimensional film of kagome metals
Julia Wildeboer, Saheli Sarkar, Alexei M. Tsvelik
We determine the nature of a phase transition in a model describing an interaction of multiple charge density waves in a two dimensional film. The model was introduced by two of th…
CeCoP: a unique Co-antiferromagnetic topological heavy-fermion system with -protected Kondo effect and nodal-line excitations
Haoyu Hu, Yi Jiang, Defa Liu +5
Based on high-throughput screening and experimental data, we find that CeCoP is unique in heavy-fermion materials: it has a Kondo effect at a high temperature which is none…
Relevance of Anisotropy in the Kondo Effect: Lessons From the Symplectic Case
Matan Lotem, Sarath Sankar, Tianhao Ren +5
A Kondo model with symplectic symmetry was recently put forward as the effective low-energy theory of a superconducting-island device coupled to multiple leads. This model, which p…
Interaction-enhanced nesting in Spin-Fermion and Fermi-Hubbard models
R. Rossi, F. Simkovic, M. Ferrero +4
The spin-fermion (SF) model postulates that the dominant coupling between low-energy fermions in near critical metals is mediated by collective spin fluctuations (paramagnons) peak…
A mesoscopic device for a realization of the Topological Kondo effect
Saheli Sarkar, Alexei M. Tsvelik
The search for anyons is a field of immense interest owing to its potential application in the field of quantum information. Quantum critical Kondo impurities constitute one possib…
Phase Switch Driven by the Hidden Half-Ice, Half-Fire State in a Ferrimagnet
Weiguo Yin, A. M. Tsvelik
The notion of "half fire, half ice" was recently introduced to describe an exotic macroscopic ground-state degeneracy emerging in a ferrimagnet under the critical magnetic field, i…
