We show conclusively that a pseudogap state can arise at , for reasonable pairing interaction strength, from order parameter fluctuations in a two dimensional minimal mode…
Effect of interlayer coupling and symmetry on high-order harmonic generation from monolayer and bilayer hexagonal boron nitride
Dasol Kim, Yeon Lee, Alexis Chacón +1
High-order harmonic generation (HHG) is a fundamental process which can be simplified as the production of high energetic photons from a material subjected to a strong driving lase…
Conformal geometry on a class of embedded hypersurfaces in spacetimes

In this work, we study various properties of embedded hypersurfaces in decomposed spacetimes with a preferred spatial direction, denoted , which are orthogonal to the…
Observation of spin-dependent dual ferromagnetism in perovskite ruthenates
Sungsoo Hahn, Byungmin Sohn, Minjae Kim +10
We performed in-situ angle-resolved photoemission spectroscopy (ARPES) and spin-resolved ARPES (SARPES) experiments to investigate the relationship between electronic band structur…
Global Regularity of the Vlasov-Poisson-Boltzmann System Near Maxwellian Without Angular Cutoff for Soft Potential
Dingqun Deng
We consider the non-cutoff Vlasov-Poisson-Boltzmann (VPB) system of two species with soft potential in the whole space when an initial data is near Maxwellian. Conti…
Emergent dual holographic description as a non-perturbative generalization of the Wilsonian renormalization group
Ki-Seok Kim, Shinsei Ryu, Kanghoon Lee
In holographic duality, dynamics along the emergent extra-dimensional space describes a renormalization group (RG) flow of the corresponding quantum field theory (QFT). Following t…
Optical excitation of electromagnons in hexaferrite
Hiroki Ueda, Hoyoung Jang, Sae Hwan Chun +11
Understanding ultrafast magnetization dynamics on the microscopic level is of strong current interest due to the potential for applications in information storage. In recent years,…
Twisted van der Waals Josephson junction based on high-Tc superconductor
Jongyun Lee, Wonjun Lee, Gi-Yeop Kim +8
Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for the study of exotic quantum phenomena. Especially, anisotropic layere…
Analytic long-lived modes in charged critical plasma
Umut Gursoy, Matti Järvinen, Giuseppe Policastro +1
Fluctuations around critical behavior of a holographic charged plasmas are investigated by studying quasi-normal modes of the corresponding black branes in 5D Einstein-Maxwell-Dila…
CaCuRuO: a high Kondo-temperature transition metal oxide

Hee-Cheol Kim, Sung-Soo Kim, Kimyeong Lee
We explore the S-foldings of some 5d superconformal field theories from the 5-brane web perspective. The S-folding involves both a spatial quotient a…
BLEND: A Fast, Memory-Efficient, and Accurate Mechanism to Find Fuzzy Seed Matches in Genome Analysis
Can Firtina, Jisung Park, Mohammed Alser +8
Generating the hash values of short subsequences, called seeds, enables quickly identifying similarities between genomic sequences by matching seeds with a single lookup of their h…
Orbital Dynamics in Centrosymmetric Systems
Seungyun Han, Hyun-Woo Lee, Kyoung-Whan Kim
Orbital dynamics in time-reversal-symmetric centrosymmetric systems is examined theoretically. Contrary to common belief, we demonstrate that many aspects of orbital dynamics are q…
Python's Lunches in Jackiw-Teitelboim gravity with matter
