Symmetry-resolved dynamical purification in synthetic quantum matter [PDF]
SciPost Physics, 2021 When a quantum system initialized in a product state is subjected to either coherent or incoherent dynamics, the entropy of any of its connected partitions generically increases as a function of time, signalling the inevitable spreading of (quantum ...

Topologically protected optical signal processing using parity–time-symmetric oscillation quenching
Nanophotonics, 2021 The concept of topology is universally observed in various physical objects when the objects can be described by geometric structures. Although a representative example is the knotted geometry of wavefunctions in reciprocal space for quantum Hall family ...

Tissue geometry drives deterministic organoid patterning
Science, 2022 Description Spatial and temporal organoid control Stem cell–derived organoids form through self-organization and serve as models for organ development, function, and disease, with potential applications in drug development and personalized medicine ...

Global Geometry of Bayesian Statistics
Entropy, 2020 In the previous work of the author, a non-trivial symmetry of the relative entropy in the information geometry of normal distributions was discovered. The same symmetry also appears in the symplectic/contact geometry of Hilbert modular cusps. Further, it

Corner Symmetry and Quantum Geometry
, 2023 By virtue of the Noether theorems, the vast gauge redundancy of general relativity provides us with a rich algebra of boundary charges that generate physical symmetries. These charges are located at codimension-2 entangling surfaces called corners.

Local conformal symmetry in non-Riemannian geometry and the origin of physical scales [PDF]
The European Physical Journal C, 2016 We introduce an extension of the Standard Model and General Relativity built upon the principle of local conformal invariance, which represents a generalization of a previous work by Bars, Steinhardt and Turok. This is naturally realized by adopting as a

Torsional string Newton-Cartan geometry for non-relativistic strings [PDF]
Journal of High Energy Physics, 2021 We revisit the formulation of non-relativistic (NR) string theory and its target space geometry. We obtain a new formulation in which the geometry contains a two-form field that couples to the tension current and that transforms under string Galilei ...

Symmetries of parabolic geometries
Differential Geometry and its Applications, 2009 We generalize the concept of affine locally symmetric spaces for parabolic geometries. We discuss mainly $|1|$--graded geometries and we show some restrictions on their curvature coming from the existence of symmetries. We use the theory of Weyl structures to discuss more interesting $|1|$--graded geometries which can carry a symmetry in a point with ...

Trineodymium(III) pentairon(III) dodecaoxide, Nd3Fe5O12
Acta Crystallographica Section E, 2009 The title compound, Nd3Fe5O12 (NdIG), has an iron garnet structure. One of the Fe atoms is coordinated by six O atoms in a slightly distorted octahedral geometry and has overline{3} site symmetry.

Chiral geometry in symmetry restored states: Chiral doublet bands in 128Cs [PDF]
, 2017 The pairing-plus-quadrupole Hamiltonian is diagonalized in a symmetry restored basis, i.e., the triaxial quasiparticle-states with angular momentum and particle number projections, and applied for chiral doublet bands in 128Cs.
