Strain Tuning of Orbital-Driven Giant Magnetoresistance in van der Waals ferrimagnet MnSiTe
Abdul Ahad, Miuko Tanaka, Shunta Aoki +7
Strain engineering of magnetotransport offers a powerful strategy for uncovering emergent electronic and domain phenomena in quantum magnetic materials, while providing a promising…
Emergence of Resonating Valence-Bond Correlations in Stretched Graphene
Sam Azadi, A. Principi, T. D. Kühne +1
Electronic correlations in graphene are generally considered weak due to the large bandwidth of its electrons. Here we show that tensile expansion of the honeycomb lattice pro…
Non-Fermi-liquid behaviour of electrons coupled to gauge phonons
Rutvij Gholap, Alexey Ermakov, Alexander Kazantsev +3
We identify overdamped gauge phonons as a new microscopic route to non-Fermi-liquid behaviour in Dirac materials. These phonons couple to electronic currents rather than densities,…
Universal Multifractality at the Topological Anderson Insulator Transition
Ksenija Kovalenka, Ahmad Ranjbar, Sam Azadi +3
Disorder is ubiquitous in quantum materials, and its interplay with topology can generate phases absent in the clean limit. Using the Haldane model as a minimal setting, we show th…
Electronic-Entropy-Driven Solid-Solid Phase Transitions in Elemental Metals
S. Azadi, S. M. Vinko, A. Principi +2
We compute the thermodynamic phase diagram of seventeen elemental metals with hexagonal close-packed (hcp), face-centered cubic (fcc), and body-centered cubic (bcc) crystal structu…
Magnetic resonance and microwave resistance modulation in van der Waals colossal-magnetoresistance material
Miuko Tanaka, Abdul Ahad, Darius-Alexandru Deaconu +8
Colossal magnetoresistance (CMR) is a fascinating quantum phenomenon that continues to draw significant interest in condensed matter physics. Mn3Si2Te6 has emerged as a prototypica…
