Nonlinear excitonic spin Hall effect in monolayer transition metal dichalcogenides
Alireza Taghizadeh, T. G. Pedersen
We propose and analyze a mechanism for inducing spin Hall currents in ordinary (1H phase) monolayer transition metal dichalcogenides (TMDs) due to the nonlinear process of optical…

Carlos Galindo, Fernando Hernando, Ryutaroh Matsumoto +1
We prove that the known formulae for computing the optimal number of maximally entangled pairs required for entanglement-assisted quantum error-correcting codes (EAQECCs) over the…
Rate-Distortion-Perception Tradeoff of Variable-Length Source Coding for General Information Sources
Ryutaroh Matsumoto
Blau and Michaeli recently introduced a novel concept for inverse problems of signal processing, that is, the perception-distortion tradeoff. We introduce their tradeoff into the r…
Optimization of Battery Energy Storage to Improve Power System Oscillation Damping
Yongli Zhu, Chengxi Liu, Kai Sun +2
A placement problem for multiple Battery Energy Storage System (BESS) units is formulated towards power system transient voltage stability enhancement in this paper. The problem is…
Effects of Lombard Reflex on the Performance of Deep-Learning-Based Audio-Visual Speech Enhancement Systems
Daniel Michelsanti, Zheng-Hua Tan, Sigurdur Sigurdsson +1
Humans tend to change their way of speaking when they are immersed in a noisy environment, a reflex known as Lombard effect. Current speech enhancement systems based on deep learni…
On Training Targets and Objective Functions for Deep-Learning-Based Audio-Visual Speech Enhancement
Daniel Michelsanti, Zheng-Hua Tan, Sigurdur Sigurdsson +1
Audio-visual speech enhancement (AV-SE) is the task of improving speech quality and intelligibility in a noisy environment using audio and visual information from a talker. Recentl…
Recurrent Multi-Graph Neural Networks for Travel Cost Prediction
Jilin Hu, Chenjuan Guo, Bin Yang +2
Origin-destination (OD) matrices are often used in urban planning, where a city is partitioned into regions and an element (i, j) in an OD matrix records the cost (e.g., travel tim…
Impedance-Based Stability Analysis for Interconnected Converter Systems with Open-Loop RHP Poles
Yicheng Liao, Xiongfei Wang
Small-signal instability issues of interconnected converter systems can be addressed by the impedance-based stability analysis method, where the impedance ratio at the point of com…
Design-Oriented Transient Stability Analysis of PLL-Synchronized Voltage-Source Converters
Heng Wu, Xiongfei Wang
Differing from synchronous generators, there are lack of physical laws governing the synchronization dynamics of voltage-source converters (VSCs). The widely used phase-locked loop…
Minimizing the Age of Information from Sensors with Common Observations
Anders E. Kalør, Petar Popovski
We study the average Age of Information (AoI) in a system where physical sources produce independent discrete-time updates that are each observed by several sensors. We devise a mo…
Classical Access Structures of Ramp Secret Sharing Based on Quantum Stabilizer Codes
Ryutaroh Matsumoto
In this paper we consider to use the quantum stabilizer codes as secret sharing schemes for classical secrets. We give necessary and sufficient conditions for qualified and forbidd…
Optical orientation with linearly polarized light in transition metal dichalcogenides
G. Catarina, J. Have, J. Fernández-Rossier +1
We study the optical properties of semiconducting transition metal dichalcogenide monolayers under the influence of strong out-of-plane magnetic fields, using the effective massive…
Co(CO)n/Cu(001): Towards understanding chemical control of the Kondo effect
Marc Philipp Bahlke, Peter Wahl, Lars Diekhöner +1
The Kondo effect is a many-body phenomenon allowing insight into the electronic and atomistic structure of spin-polarized adsorbates on metal surfaces. Its chemical control is intr…
Rain Removal in Traffic Surveillance: Does it Matter?
Chris H. Bahnsen, Thomas B. Moeslund
Varying weather conditions, including rainfall and snowfall, are generally regarded as a challenge for computer vision algorithms. One proposed solution to the challenges induced b…
Ultra-thin titanium nitride films for refractory spectral selectivity
Alexander S. Roberts, Manohar Chirumamilla, Deyong Wang +4
We demonstrate a selectively emitting optical Fabry-Pérot resonator based on a few-nm-thin continuous metallic titanium nitride film, separated by a dielectric spacer from an optic…
Development of a Computationally Efficient Fabric Model for Optimization of Gripper Trajectories in Automated Composite Draping
Christian Krogh, Johnny Jakobsen, James A. Sherwood
An automated prepreg fabric draping system is being developed which consists of an array of actuated grippers. It has the ability to pick up a fabric ply and place it onto a double…
Monolayer transition metal dichalcogenides in strong magnetic fields: Validating the Wannier model using a microscopic calculation
J. Have, G. Catarina, T. G. Pedersen +1
Using an equation of motion (EOM) approach, we calculate excitonic properties of monolayer transition metal dichalcogenides (TMDs) perturbed by an external magnetic field. We compa…
