Symmetric Trotterization in digital quantum simulation of quantum spin dynamics
Yeonghun Lee
A higher-order Suzuki-Trotter decomposition or Trotterization can be exploited to mitigate the Trotter error in digital quantum simulation. This work revisits the second-order symm…
Tight-Binding Device Modeling of 2-D Topological Insulator Field-Effect Transistors With Gate-Induced Phase Transition
Yungyeong Park, Yosep Park, Hyeonseok Choi +3
Topological insulator field-effect transistors (TIFETs) built on 2-D quantum spin Hall insulators are being considered as advanced logic transistors due to their potentially superi…
Effect of Localization on Photoluminescence and Zero-Field Splitting of Silicon Color Centers
Vsevolod Ivanov, Jacopo Simoni, Yeonghun Lee +10
The study of defect centers in silicon has been recently reinvigorated by their potential applications in optical quantum information processing. A number of silicon defect centers…
Two Types of 3D Quantum Hall Effects in Multilayer WTe
Xurui Zhang, Yeonghun Lee, Vivek Kakani +3
Interplay between the topological surface states and bulk states gives rise to diverse exotic transport phenomena in topological materials. The recently proposed Weyl orbit in topo…
Real-time ab initio simulation of inelastic electron scattering using the exact, density functional, and alternative approaches
Yeonghun Lee, Xiaolong Yao, Massimo V. Fischetti +1
To investigate inelastic electron scattering, which is ubiquitous in various fields of study, we carry out ab initio study of the real-time dynamics of a one-dimensional electron w…
First-principles study of metal-graphene edge contact for ballistic Josephson junction
Yeonghun Lee, Jeongwoon Hwang, Fan Zhang +1
Edge-contacted superconductor-graphene-superconductor Josephson junction have been utilized to realize topological superconductivity, which have shown superconducting signatures in…
