Origin of chirality in transition-metal dichalcogenides
Kwangrae Kim, Hyun-Woo J. Kim, Seunghyeok Ha +15
Chirality is a ubiquitous phenomenon in which a symmetry between left- and right-handed objects is broken, examples in nature ranging from subatomic particles and molecules to livi…
IR-UWB Radar-Based Contactless Silent Speech Recognition of Vowels, Consonants, Words, and Phrases
Sunghwa Lee, Younghoon Shin, Myungjong Kim +1
Several sensing techniques have been proposed for silent speech recognition (SSR); however, many of these methods require invasive processes or sensor attachment to the skin using…
Controllable Andreev Bound States in Bilayer Graphene Josephson Junction from Short to Long Junction Limits
Geon-Hyoung Park, Wonjun Lee, Sein Park +4
We demonstrate that the mode number of Andreev bound states in bilayer graphene Josephson junctions can be modulated by in situ control of the superconducting coherence length. By…
Scalar curvature rigidity of parabolic convex polytopes in hyperbolic space
Xiaoxiang Chai, Xueyuan Wan
In odd dimensions, we prove a scalar curvature rigidity for parabolic convex polytopes in hyperbolic space enclosed by linear planes in the Poincare upper half-space model and conv…
On the Backreaction of Dirac Matter in JT Gravity and SYK Model
Pak Hang Chris Lau, Chen-Te Ma, Jeff Murugan +1
We model backreaction in AdS JT gravity via a proposed boundary dual Sachdev-Ye-Kitaev quantum dot coupled to Dirac fermion matter and study it from the perspective of quantum…
Modular extension of topological orders from congruence representations
Donghae Seo, Minyoung You, Gil Young Cho +1
We present an efficient method to compute the modular extension of both fermionic topological orders and -symmetric bosonic topological orders in two spatial dimensio…
Probing cosmology via the clustering of critical points
Junsup Shim, Christophe Pichon, Dmitri Pogosyan +5
Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, filament-void) of the density field define quasi-standard rulers that can be…
Revealing inverted chirality of hidden domain wall states in multiband systems without topological transition
Seung-Gyo Jeong, Sang-Hoon Han, Tae-Hwan Kim +1
Chirality, a fundamental concept from biological molecules to advanced materials, is prevalent in nature. Yet, its intricate behavior in specific topological systems remains poorly…
Magnetism in AV3Sb5 (A = Cs, Rb, K): Complex Landscape of the Dynamical Magnetic Textures
Debjani Karmakar, Manuel Pereiro, Md. Nur Hasan +10
We have investigated the dynamical magnetic properties of the V-based kagome stibnite compounds by combining the ab-initio calculated magnetic parameters of a spin Hamiltonian like…
Magnetism in AV3Sb5 (Cs, Rb, K): Origin and Consequences for the Strongly Correlated Phases
Md. Nur Hasan, Ritadip Bharati, Johan Hellsvik +10
The V-based kagome systems AV3Sb5 (A = Cs, Rb and K) are unique by virtue of the intricate interplay of non-trivial electronic structure, topology and intriguing fermiology, render…
Gapped boundaries of fermionic topological orders and higher central charges
Minyoung You
We develop a test for the vanishing of higher central charges of a fermionic topological order, which is a necessary condition for the existence of a gapped boundary, purely in ter…
The Mixed Convex-Concave effect on the regularity of a Boltzmann solution
Gayoung An, Donghyun Lee
The geometric properties of domains are well-known to be crucial factors influencing the regularity of Boltzmann boundary problems. In the presence of non-convex physical boundarie…
Revealing the Charge Density Wave Proximity Effect in Graphene on 1T-TaS
