Spin Transport in Magnetically Ordered Systems: Ferromagnets, Antiferromagnets and Frustrated Systems
Danh-Tai Hoang, Hung T. Diep
In this review, we outline the important results on the resistivity encountered by an electron in magnetically ordered materials. The mechanism of the collision between the electro…
Inverse Ising inference from high-temperature re-weighting of observations
Junghyo Jo, Danh-Tai Hoang, Vipul Periwal
Maximum Likelihood Estimation (MLE) is the bread and butter of system inference for stochastic systems. In some generality, MLE will converge to the correct model in the infinite d…
Data-driven inference of hidden nodes in networks
Danh-Tai Hoang, Junghyo Jo, Vipul Periwal
The explosion of activity in finding interactions in complex systems is driven by availability of copious observations of complex natural systems. However, such systems, e.g. the h…
Causality inference in stochastic systems from neurons to currencies: Profiting from small sample size
Danh-Tai Hoang, Juyong Song, Vipul Periwal +1
Success in modeling complex phenomena such as human perception hinges critically on the availability of data and computational power. Significant progress has been made in modeling…
A Local Counter-Regulatory Motif Modulates the Global Phase of Hormonal Oscillations
Dong-Ho Park, Taegeun Song, Danh-Tai Hoang +2
Counter-regulatory elements maintain dynamic equilibrium ubiquitously in living systems. The most prominent example, which is critical to mammalian survival, is that of pancreatic…
Design Principles of Pancreatic Islets: Glucose-dependent Coordination of Hormone Pulses
Danh-Tai Hoang, Manami Hara, Junghyo Jo
Pancreatic islets are functional units involved in glucose homeostasis. The multicellular system comprises three main cell types; and cells reciprocally decrease and increa…
Minimal Perceptrons for Memorizing Complex Patterns
Marissa Pastor, Juyong Song, Danh-Tai Hoang +1
Feedforward neural networks have been investigated to understand learning and memory, as well as applied to numerous practical problems in pattern classification. It is a rule of t…
Emergent Universality in Nonequilibrium Processes of Critical Systems
Danh-Tai Hoang, B. Prasanna Venkatesh, Seungju Han +3
We examine the Jarzynski equality for a quenching process across the critical point of second-order phase transitions, where absolute irreversibility and the effect of finite-sampl…
Magnetic Properties of Two-dimensional Nanodots: Ground State and Phase Transition
Maciej Kasperski, H. Puszkarski, Danh-Tai Hoang +1
We study the effect of perpendicular single-ion anisotropy, , on the ground-state structure and finite-temperature properties of a two-dimensional magnetic nanodo…
Theory and Simulation of Magnetic Materials: Physics at Phase Frontiers
Hung T. Diep, Virgile Bocchetti, Danh-Tai Hoang +1
The combination of theory and simulation is necessary in the investigation of properties of complex systems where each method alone cannot do the task properly. Theory needs simula…
Phase Transition in Dimer Liquids
Danh-Tai Hoang, Hung T. Diep
We study the phase transition in a system composed of dimers interacting with each other via a nearest-neighbor (NN) exchange and competing interactions taken from a truncated…
Re-orientation Transition in Molecular Thin Films: Potts Model with Dipolar Interaction
Danh-Tai Hoang, Maciej Kasperski, Henryk Puszkarski +1
We study the low-temperature behavior and the phase transition of a thin film by Monte Carlo simulation. The thin film has a simple cubic lattice structure where each site is occup…
Hexagonal-Close-Packed Lattice: Phase Transition and Spin Transport
Danh-Tai Hoang, H. T. Diep
We study the ground state (GS) and the phase transition in a hexagonal-close-packed lattice with both XY and Ising models by using extensive Monte Carlo simulation. We suppose the…
Effect of Dipolar Interaction in Molecular Crystals
Danh-Tai Hoang, H. T. Diep
We investigate in this paper the ground state and the nature of the transition from an orientational ordered phase at low temperature to the disordered state at high temperature in…
Spin transport in magnetically ordered systems: effect of the lattice relaxation time
Yann Magnin, Danh-Tai Hoang, Hung The Diep
Spin resistivity has been shown to result mainly from the scattering of itinerant spins with magnetic impurities and lattice spins. is proportional to the spin-spin correla…
Spin Resistivity in the Frustrated Model
Danh-Tai Hoang, Yann Magnin, Hung The Diep
We study in this paper the resistivity encountered by Ising itinerant spins traveling in the so-called frustrated simple cubic Ising lattice. For the lattice, we take int…
