Generating ferro-spinetic polarizations in altermagnetic insulators
Toshihiro Sato, Mengli Hu, Ion Cosma Fulga +5
Altermagnets are a novel class of fully spin-compensated magnetic materials that nevertheless have spin-split electronic bands, offering novel perspectives for spintronics applicat…
Revealing altermagnetic Fermi surfaces with two Kondo impurities
Qiong Qin, Toshihiro Sato, Marcin Raczkowski +3
Motivated by recent advances in the study of altermagnetism, or unconventional magnetism, and in the realization and manipulation of two-impurity Kondo physics in real materials, w…
Edge modes of topological Mott insulators and deconfined quantum critical points
Yuhai Liu, Toshihiro Sato, Disha Hou +3
Topology and anomalies lead to edge modes that can interact with critical bulk fluctuations. To study this setup, pertaining to boundary criticality, we consider a model exhibiting…
Alteration of Topology in Quantum Phase Transitions via Symmetry Enrichment
Gabriel Rein, Marcin Raczkowski, Zhenjiu Wang +2
Topology plays a cardinal role in explaining phases and quantum phase transitions beyond the Landau-Ginzburg-Wilson paradigm. In this study, we formulate a set of models of Dirac f…
Finite temperature fermion Monte Carlo simulations of frustrated spin-Peierls systems
João C. Inácio, Jeroen van den Brink, Fakher F. Assaad +1
The Abrikosov fermion representation of the spin-1/2 degree of freedom allows for auxiliary-field quantum Monte Carlo simulations of frustrated spin systems. This approach provides…
