Coexistence of magnetic and dielectric glassy states in alternating kagome and triangular lattice LuBaCoO cobaltite
C. Dhanasekhar, D. Chandrasekhar Kakarla, Archana kumari +10
To date, the alternating kagome and triangular lattice cobaltites, RBaCoO (R = Ca, Y, and rare earth elements), have been well studied for their large structural distortion…
Susceptibility anisotropy and absence of ferroelectric order in the Kitaev spin liquid candidate NaCoTeO
C. Dhanasekhar, Monika Jawale, Rahul Kumar +6
We report the magnetic, magnetodielectric, and electric polarization properties of single crystals of the Co-based Kitaev Spin Liquid (KSL) candidate NaCoTeO (NCTO). Th…
Anomalous temperature-dependent magnetization in the nearly collinear antiferromagnet YCo
Yunshu Shi, Huibo Cao, Hung-Cheng Wu +17
YCo is a newly discovered antiferromagnetic (AFM) compound with distorted kagome layers. Previous investigations via bulk magnetization measurements suggested a complex non…
The topological Kondo model out of equilibrium
Matteo M. Wauters, Chia-Min Chung, Lorenzo Maffi +1
The topological Kondo effect is a genuine manifestation of the nonlocality of Majorana modes. We investigate its out-of-equilibrium signatures in a model with a Cooper-pair box hos…
Simulations of the dynamics of quantum impurity problems with matrix product states
Matteo M. Wauters, Chia-Min Chung, Lorenzo Maffi +1
The Anderson impurity model is a paradigmatic example in the study of strongly correlated quantum systems and describes an interacting quantum dot coupled to electronic leads. In t…
An emergent quasi-2D metallic state derived from the Mott insulator framework
P. -C. Chiang, S. C. Lin, C. -Y. Chiang +17
Recent quasi-2D systems with judicious exploitation of the atomic monolayer or few-layer architecture exhibit unprecedented physical properties that challenge the conventional wisd…
