Quantitative study of electronic whispering gallery modes in electrostatic-potential induced circular graphene junctions
Thi Lien Le, Van Lien Nguyen
Electronic Whispering Gallery Modes (EWGMs) have been recently observed in several circular graphene junctions, pn and pp0, created in scanning tunnelling microscope experiments. B…
Gamma-ray Burst Afterglows: Time-Varying Extinction, Polarization, and Colors due to Rotational Disruption of Dust Grains
Thiem Hoang, Nguyen Chau Giang, Le Ngoc Tram
Prompt optical emission of gamma-ray bursts (GRBs) is known to have important effects on the surrounding environment. In this paper, we study rotational disruption and alignment of…
Physical Model of Dust Polarization by Radiative Torque Alignment and Disruption and Implications for Grain Internal Structures
Hyeseung Lee, Thiem Hoang, Ngan Le +1
Dust polarization depends on the physical and mechanical properties of dust, as well as the properties of local environments. To understand how dust polarization varies with grain…
Supernova Shocks in Molecular Clouds: Velocity Distribution of Molecular Hydrogen
William T. Reach, Le Ngoc Tram, Matthew Richter +2
Supernovae from core-collapse of massive stars drive shocks into the molecular clouds from which the stars formed. Such shocks affect future star formation from the molecular cloud…
Confinement effect on solar thermal heating process of TiN solutions
Anh D. Phan, Nam B. Le, Nghiem T. H. Lien +3
We propose a theoretical approach to describe quantitatively the heating process in aqueous solutions of dispersed TiN nanoparticles under solar illumination. The temperature gradi…
Impacts of Retina-related Zones on Quality Perception of Omnidirectional Image
Huyen T. T. Tran, Duc V. Nguyen, Nam Pham Ngoc +3
Virtual Reality (VR), which brings immersive experiences to viewers, has been gaining popularity in recent years. A key feature in VR systems is the use of omnidirectional content,…
Loss Minimization with Optimal Power Dispatch in Multi-Frequency HVac Power Systems
Quan Nguyen, Keng-Weng Lao, Phuong Vu +1
Low-frequency high voltage ac transmission scheme has recently been proposed as an alternative approach for bulk power transmission. This paper proposes a multi-period optimal powe…
New Approach for Solving The Clustered Shortest-Path Tree Problem Based on Reducing The Search Space of Evolutionary Algorithm
Huynh Thi Thanh Binh, Pham Dinh Thanh, Ta Bao Thang
Along with the development of manufacture and services, the problem of distribution network optimization has been growing in importance, thus receiving much attention from the rese…
The Hubbard model on the honeycomb lattice: from static and dynamical mean-field theories to lattice quantum Monte Carlo simulations
Marcin Raczkowski, Robert Peters, Th\d{i} Thu Phùng +4
We study the one-band Hubbard model on the honeycomb lattice using a combination of quantum Monte Carlo (QMC) simulations and static as well as dynamical mean-field theory (DMFT).…
Modeling rotational disruption of grains and microwave emission from spinning dust in AGB envelopes
Le Ngoc Tram, Thiem Hoang, Archana Soam +2
Radio observations of some Asymptotic Giant Branch (AGB) star envelopes show the excess emission at frequencies below 100 GHz which cannot be explained by thermal dust emission (he…
Alternative Renormalizable Minimal SO(10) GUTs and Data Fitting
Takeshi Fukuyama, Nobuchika Okada, Hieu Minh Tran
The alternative renormalizable minimal model is composed of the Yukawa couplings with Higgs fields, whereas the right-handed (RH) neutrin…
Time-Varying Extinction, Polarization, and Colors of Type Ia Supernovae due to Rotational Disruption of Dust Grains
Nguyen Chau Giang, Thiem Hoang, Le Ngoc Tram
Photometric and polarimetric observations toward type Ia supernovae (SNe Ia) frequently report an unusually low total-to-selective extinction ratio () and small peak…
Chemistry on Rotating Grain Surface: Ro-Thermal Desorption of Molecules from Ice Mantles
Thiem Hoang, Ngo-Duy Tung
It is widely believed that water and complex organic molecules (COMs) first form in the ice mantle of dust grains and are subsequently returned into the gas due to grain heating by…
The MBHBM* Project -- I: Measurement of the Central Black Hole Mass in Dwarf Galaxy NGC 3504 Using Molecular Gas Kinematics
Dieu D. Nguyen, Mark den Brok, Anil C. Seth +19
We present the first measurement of the mass of a supermassive black hole (SMBH) in the nearby double-barred spiral galaxy NGC 3504 as part of the Measuring Black Holes Below the M…
Superconductivity under pressure in the Dirac semimetal PdTe2
H. Leng, A. Ohmura, L. N. Anh +4
The Dirac semimetal PdTe was recently reported to be a type-I superconductor (1.64 K, mT) with unusual superconductivity of the surface sheath. We…
Rotational Desorption of Ice Mantles and Complex Molecules from Suprathermally Rotating Dust Grains around Young Stellar Objects
Thiem Hoang, Le Ngoc Tram
Ice mantles on dust grains play a central role in astrochemistry. Water and complex organic molecules (COMs) are thought to first form on the ice mantles and subsequently are relea…
Dust rotational dynamics in non-stationary shock: rotational disruption of nanoparticles by stochastic mechanical torques and spinning dust emission
Le Ngoc Tram, Thiem Hoang
In a previous work, Hoang and Tram discovered a new mechanism for destruction of nanoparticles due to suprathermal rotation of grains in stationary C-shocks, which is termed rotati…
Bandpass mismatch error for satellite CMB experiments II: Correcting for the spurious signal
Ranajoy Banerji, Guillaume Patanchon, Jacques Delabrouille +4
Future Cosmic Microwave Background (CMB) satellite missions aim at using the B-mode polarisation signal to measure the tensor-to-scalar ratio with a sensitivity of the o…
Four-wave mixing in spin-orbit coupled Bose-Einstein condensates
Nguyen Viet Hung, Piotr Szankowski, Vladimir V. Konotop +1
We describe possibilities of spontaneous, degenerate four-wave mixing (FWM) processes in spin-orbit coupled Bose-Einstein condensates. Phase matching conditions (i.e., energy and m…
