Experimental Realization of Geometry-Dependent Skin Effect in a Reciprocal Two-Dimensional Lattice. [PDF]
Physical Review Letters, 2023 Recent studies of non-Hermitian periodic lattices unveiled the non-Hermitian skin effect (NHSE), in which the bulk modes under the periodic boundary conditions (PBC) become skin modes under open boundary conditions. The NHSE is a topological effect owing

Symmetry, Geometry and Quantization with Hypercomplex Numbers [PDF]
, 2016 These notes describe some links between the group SL2(R), the Heisenberg group and hypercomplex numbers - complex, dual and double numbers. Relations between quantum and classical mechanics are clarified in this framework.

The Branes Behind Generalized Symmetry Operators [PDF]
Fortschritte der Physik, 2022 The modern approach to m‐form global symmetries in a d‐dimensional quantum field theory (QFT) entails specifying dimension d−m−1$d-m-1$ topological generalized symmetry operators which non‐trivially link with m‐dimensional defect operators.

Non-metric geometry as the origin of mass in gauge theories of scale invariance
European Physical Journal C: Particles and Fields, 2023 We discuss gauge theories of scale invariance beyond the Standard Model (SM) and Einstein gravity. A consequence of gauging this symmetry is that their underlying 4D geometry is non-metric ( $$\nabla _\mu g_{\alpha \beta }\!\not =\!0$$ ∇ μ g α β ≠ 0 ...

Geometry and Symmetry in Short-and-Sparse Deconvolution [PDF]
International Conference on Machine Learning, 2019 We study the $\textit{Short-and-Sparse (SaS) deconvolution}$ problem of recovering a short signal $\mathbf a_0$ and a sparse signal $\mathbf x_0$ from their convolution.

Geometries with the Second Poincaré Symmetry [PDF]
Communications in Theoretical Physics, 2012 The second Poincar kinematical group serves as one of new ones in addition to the known possible kinematics. The geometries with the second Poincar symmetry is presented and their properties are analyzed. On the geometries, the new mechanics based on the principle of relativity with two universal constants $(c,l)$ can be established.

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

Symmetry, spin-texture, and tunable quantum geometry in a WTe2 monolayer [PDF]
Physical review B, 2018 The spin orientation of electronic wavefunctions in crystals is an internal degree of freedom, typically insensitive to electrical knobs. We argue from a general symmetry analysis and a $\vec k \cdot \vec p$ perspective, that monolayer 1T'-WTe$_2 ...

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 ...

Uncovering Conformal Symmetry in the 3D Ising Transition: State-Operator Correspondence from a Quantum Fuzzy Sphere Regularization [PDF]
Physical Review X, 2022 The $3D$ Ising transition, the most celebrated and unsolved critical phenomenon in nature, has long been conjectured to have emergent conformal symmetry, similar to the case of the $2D$ Ising transition. Yet, the emergence of conformal invariance in the $
