Field-rigid Ising antiferromagnetism with giant spin-flip fields in Van der Waals UOTe
Zackary Rehfuss, Shannon Gould, Joanna Blawat +9
Van der Waals antiferromagnets provide a route to thickness-controlled magnetic order, but few combine high-temperature Ising order with conducting, correlated, and topological ele…
Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator
Jian Tang, Thomas Siyuan Ding, Shuhan Ding +24
Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
Wavefunction-Free Approach for Predicting Nonlinear Responses in Weyl Semimetals
Mohammad Yahyavi, Ilya Belopolski, Yuanjun Jin +15
By sidestepping the intractable calculations of many-body wavefunctions, density functional theory (DFT) has revolutionized the prediction of ground states of materials. However, p…
Quantum Geometry Phenomena in Condensed Matter Systems
Anyuan Gao, Naoto Nagaosa, Ni Ni +1
Quantum geometry, which describes the geometry of Bloch wavefunctions in solids, has become a cornerstone of modern quantum condensed matter physics. The quantum geometrical tensor…
Pressure-tunable phase transitions in atomically thin Chern insulator MnBiTe
Albin Marffy, Endre Tovari, Yu-Fei Liu +8
Topological insulators lacking time-reversal symmetry can exhibit the quantum anomalous Hall effect. Odd-layer thick MnBiTe is a promising platform due to its intrinsic mag…
