Hysteresis without coexistence: disorder-rounded first-order transitions in a van der Waals magnet
Xiaoyu Guo, Abby N. Neill, Christopher M. Pasco +2
Quenched disorder can profoundly modify phase transitions. In low-dimensional systems, theory predicts that even weak quenched disorder can round the thermodynamic discontinuities…
Many-body quantum geometric effects and entanglement at the 3D metal-insulator quantum phase transition
Jason Y. Yan, Xiaoyu Guo, R. Bhandia +3
Quantum geometry has emerged as a unifying concept across condensed matter physics, underlying phenomena from nonlinear topological response to flat-band superconductivity. While u…
Symmetry-Resolved Second Harmonic Generation in Quantum and Functional Materials
Xiaoyu Guo, Chang Jae Roh, Youngjun Ahn
Second harmonic generation (SHG) has evolved from a probe of noncentrosymmetric crystals into a symmetry-resolved optical method for identifying order parameters in quantum and fun…
Electrotoroidicity: New Paradigm for Transverse Electromagnetic Responses
Kai Du, Daegeun Jo, Xianghan Xu +7
The exploration of transverse electromagnetic responses in solids with broken spatial-inversion (I) and/or time-reversal (T) symmetries has unveiled numerous captivating phenomena,…
Tuning Coupled Toroidic and Polar Orders in a Bilayer Antiferromagnet
Chuangtang Wang, Xiaoyu Guo, Zixin Zhai +5
Magnetic toroidal order features a loop-like arrangement of magnetic dipole moments, thus breaking both spatial inversion (P) and time-reversal (T) symmetries while preserving thei…
Intertwined polar, chiral, and ferro-rotational orders in a rotation-only insulator
Weizhe Zhang, June Ho Yeo, Xiaoyu Guo +8
Intertwined orders refer to strongly coupled and mutually dependent orders that coexist in correlated electron systems, often underpinning key physical properties of the host mater…
Emerging orthorhombic two-dimensional van der Waals magnets
Xiaoyu Guo, Wenhao Liu, Bing Lv +1
Two-dimensional (2D) magnetism realized in van der Waals (vdW) materials has expanded to include a great variety of magnetic phases, over a short decade since its first discovery i…
Incommensurate Transverse Peierls Transition
F. Z. Yang, K. F. Luo, Weizhe Zhang +19
In one-dimensional quantum materials, conducting electrons and the underlying lattices can undergo a spontaneous translational symmetry breaking, known as Peierls transition. For n…
Progress and Prospects in Two-Dimensional Magnetism of van der Waals Materials
Youngjun Ahn, Xiaoyu Guo, Suhan Son +2
Two-dimensional (2D) magnetism in van der Waals (vdW) atomic crystals and moiré superlattices has emerged as a topic of tremendous interest in the fields of condensed matter physic…
Electric quadrupole second harmonic generation revealing dual magnetic orders in a magnetic Weyl semimetal
Youngjun Ahn, Xiaoyu Guo, Rui Xue +4
Broken symmetries and electronic topology are nicely manifested together in the second order nonlinear optical responses from topologically nontrivial materials. While second order…
"Extraordinary" Phase Transition Revealed in a van der Waals Antiferromagnet
Xiaoyu Guo, Wenhao Liu, Jonathan Schwartz +12
While the surface-bulk correspondence has been ubiquitously shown in topological phases, the relationship between surface and bulk in Landau-like phases is much less explored. Theo…
