Symmetry representation approach to topological invariants in -symmetric systems
Junyeong Ahn, Bohm-Jung Yang
We study the homotopy classification of symmetry representations to describe the bulk topological invariants protected by the combined operation of a two-fold rotation and…
Crystalline topological Dirac semimetal phase in rutile structure -PtO
Rokyeon Kim, Bohm-Jung Yang, Choong H. Kim
Based on first-principles calculations and symmetry analysis, we propose that a transition metal rutile oxide, in particular -PtO, can host a three-dimensional topological…
Spin-orbit-stable type-II nodal line band crossing in n-doped monolayer MoX2 (X=S,Se,Te)
Kyung-Han Kim, Bohm Jung Yang, Hyun-Woo Lee
1H-phase monolayer transition-metal dichalcogenides have spin-split electronic band structures near the K(K') point due to strong spin-orbit coupling and intrinsic inversion symmet…
Classification of flat bands according to the band-crossing singularity of Bloch wave functions
Jun-Won Rhim, Bohm-Jung Yang
We show that flat bands can be categorized into two distinct classes, that is, singular and nonsingular flat bands, by exploiting the singular behavior of their Bloch wave function…
Deep Convolutional Networks as shallow Gaussian Processes
Adrià Garriga-Alonso, Carl Edward Rasmussen, Laurence Aitchison
We show that the output of a (residual) convolutional neural network (CNN) with an appropriate prior over the weights and biases is a Gaussian process (GP) in the limit of infinite…
The Evolution of the HeII-Ionizing Background at Redshifts 2.3<z<3.8 Inferred from a Statistical Sample of 24 HST/COS HeII Ly Absorption Spectra
Gábor Worseck, Frederick B. Davies, Joseph F. Hennawi +1
We present measurements of the large-scale (~40 comoving Mpc) effective optical depth of HeII Ly absorption, , at 2.54<z<3.86 toward 16 HeII-transparent quasars obs…
