Superfluid Weight Bounds from Symmetry and Quantum Geometry in Flat Bands. [PDF]

open access: yesPhysical Review Letters, 2021
Flat-band superconductivity has theoretically demonstrated the importance of band topology to correlated phases. In two dimensions, the superfluid weight, which determines the critical temperature through the Berezinksii-Kosterlitz-Thouless criteria, is ...

Time-reversal symmetry-breaking charge order in a kagome superconductor [PDF]

open access: yesNature, 2021
The kagome lattice1, which is the most prominent structural motif in quantum physics, benefits from inherent non-trivial geometry so that it can host diverse quantum phases, ranging from spin-liquid phases, to topological matter, to intertwined orders2–8

Rays, waves, SU(2) symmetry and geometry: toolkits for structured light

open access: yesJournal of Optics, 2021
Structured light refers to the ability to tailor optical patterns in all its degrees of freedom, from conventional 2D transverse patterns to exotic forms of 3D, 4D, and even higher-dimensional modes of light, which break fundamental paradigms and open ...

Floral symmetry: the geometry of plant reproduction

open access: yesEmerging Topics in Life Sciences, 2022
The flower is an astonishing innovation that arose during plant evolution allowing flowering plants — also known as angiosperms — to dominate life on earth in a relatively short period of geological time. Flowers are formed from secondary meristems by co-

Geometry and symmetry in skyrmion dynamics [PDF]

open access: yesPhysical Review B, 2021
The uniform motion of chiral magnetic skyrmions induced by a spin-transfer torque displays an intricate dependence on the skyrmions' topological charge and shape. We reveal surprising patterns in this dependence through simulations of the Landau-Lifshitz-Gilbert equation with Zhang-Li torque and explain them through a geometric analysis of Thiele's ...

Symmetries in Generalized Kähler Geometry [PDF]

open access: yesCommunications in Mathematical Physics, 2006
We define the notion of a moment map and reduction in both generalized complex geometry and generalized K hler geometry. As an application, we give very simple explicit constructions of bi-Hermitian structures on $\C ^n$, Hirzebruch surfaces, the blow up of $\CP^2$ at arbitrarily many points, and other toric varieties, as well as complex ...

Chemistry Students’ Understanding of Lewis Structure, VSEPR Theory, Molecular Geometry, and Symmetry: A Cross-Sectional Study

open access: yesJTK (Jurnal Tadris Kimiya), 2023
Most chemical concepts are abstract, hierarchical, and constructed from basic to complex concepts. Lewis structure, VSEPR theory, molecular geometry, and molecular symmetry have hierarchical idea.

Quantum Geometry Induced Nonlinear Transport in Altermagnets. [PDF]

open access: yesPhysical Review Letters, 2023
Quantum geometry plays a pivotal role in the second-order response of PT-symmetric antiferromagnets. Here we study the nonlinear response of 2D altermagnets protected by C_{n}T symmetry and show that their leading nonlinear response is third order ...

Weyl conformal geometry vs Weyl anomaly

open access: yesJournal of High Energy Physics, 2023
Weyl conformal geometry is a gauge theory of scale invariance that naturally brings together the Standard Model (SM) and Einstein gravity. The SM embedding in this geometry is possible without new degrees of freedom beyond SM and Weyl geometry, while ...
