An HDG Method for Distributed Control of Convection Diffusion PDEs
Weiwei Hu, Jiguang Shen, John R. Singler +2
We propose a hybridizable discontinuous Galerkin (HDG) method to approximate the solution of a distributed optimal control problem governed by an elliptic convection diffusion PDE.…
HDG-POD Reduced Order Model of the Heat Equation

We propose a new hybridizable discontinuous Galerkin (HDG) model order reduction technique based on proper orthogonal decomposition (POD). We consider the heat equation as a test p…
Superfluid density and compressibility at the superfluid-Mott glass transition
Cameron Lerch, Thomas Vojta
Systems of disordered interacting bosons with particle-hole symmetry can undergo a quantum phase transition between the superfluid phase and the Mott glass phase which is a gapless…

An all-optical atom trap as a target for MOTRIMS-like collision experiments
S. Sharma, B. P. Acharya, A. H. N. C. De Silva +5
Momentum-resolved scattering experiments with laser-cooled atomic targets have been performed since almost two decades with MOTRIMS (Magneto-Optical Trap Recoil Ion Momentum Spectr…
On the Global Convergence of Continuous-Time Stochastic Heavy-Ball Method for Nonconvex Optimization
Wenqing Hu, Chris Junchi Li, Xiang Zhou
We study the convergence behavior of the stochastic heavy-ball method with a small stepsize. Under a change of time scale, we approximate the discrete method by a stochastic differ…
Long-Range Interactions for Hydrogen: 6P-1S and 6P-2S
U. D. Jentschura, C. M. Adhikari
The collisional shift of a transition constitutes an important systematic effect in high-precision spectroscopy. Accurate values for van der Waalsinteraction coefficients are requi…
Stability and convergence analysis of A linear, fully decoupled and unconditionally energy stable scheme for magneto-hydrodynamic equations
Guodong Zhang, Xiaoming He, Xiaofeng Yang
In this paper, we consider numerical approximations for solving the nonlinear magneto-hydrodynamical system, that couples the Navier-Stokes equations and Maxwell equations together…
BL-MNE: Emerging Heterogeneous Social Network Embedding through Broad Learning with Aligned Autoencoder
Jiawei Zhang, Congying Xia, Chenwei Zhang +3
Network embedding aims at projecting the network data into a low-dimensional feature space, where the nodes are represented as a unique feature vector and network structure can be…
A comparative study on nonlocal diffusion operators related to the fractional Laplacian
Siwei Duo, Hong Wang, Yanzhi Zhang
In this paper, we study four nonlocal diffusion operators, including the fractional Laplacian, spectral fractional Laplacian, regional fractional Laplacian, and peridynamic operato…
Neutrino Pair Cerenkov Radiation for Tachyonic Neutrinos
Ulrich D. Jentschura, Istvan Nandori
The emission of a charged light lepton pair by a superluminal neutrino has been identified as a major factor in the energy loss of highly energetic neutrinos. The observation of Pe…
Fractional Brownian motion with a reflecting wall
Alexander H. O. Wada, Thomas Vojta
Fractional Brownian motion, a stochastic process with long-time correlations between its increments, is a prototypical model for anomalous diffusion. We analyze fractional Brownian…
Attack Analysis for Distributed Control Systems: An Internal Model Principle Approach
Rohollah Moghadam, Hamidreza Modares
Although adverse effects of attacks have been acknowledged in many cyber-physical systems, there is no system-theoretic comprehension of how a compromised agent can leverage commun…

Wenqing Hu, Michael Salins, Konstantinos Spiliopoulos
We study a large deviation principle for a system of stochastic reaction--diffusion equations (SRDEs) with a separation of fast and slow components and small noise in the slow comp…

C. M. Adhikari, V. Debierre, U. D. Jentschura
The long-range interaction of excited neutral atoms has a number of interesting and surprising properties, such as the prevalence of long-range, oscillatory tails, and the emergenc…

We consider in detail the calculation of the decay rate of high-energy superluminal neutrinos against (charged) lepton pair Cerenkov radiation (LPCR), and neutrino pair Cerenkov ra…
An efficient, partitioned ensemble algorithm for simulating ensembles of evolutionary MHD flows at low magnetic Reynolds number
Nan Jiang, Michael Schneier
Studying the propagation of uncertainties in a nonlinear dynamical system usually involves generating a set of samples in the stochastic parameter space and then repeated simulatio…
