Topological Structure of a Vortex in Fulde-Ferrell-Larkin-Ovchinnikov State

, 2005
We find theoretically that the vortex core in the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is quite different from the ordinary core by a simple topological reason.

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Harmonic calculation method for non-synchronous sampling data based on Hermite interpolation

Diance yu yibiao
The high cost of power quality monitoring makes it difficult to install them on a large scale in distribution network, resulting in incomplete information on nodal harmonic monitoring.

Electrodynamics of the Nodal Metal in Weakly Doped High-$T_{c}$ Cuprates

, 2005
We report on the detailed analysis of the infrared (IR) conductivity of two prototypical high-$T_{c}$ systems YBa$_{2}$Cu$_{3}$O$_{y}$ and La$_{2-x}$Sr$%_{x}$CuO$_{4}$ throughout the complex phase diagram of these compounds.

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

Contributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Water waves scattering by floating rigid dock and breakwaters using improved singular boundary method under regular and irregular waves

Results in Engineering
This study explores the interaction between water waves and a pair of porous trapezoidal-shaped breakwaters of varying sizes kept at a finite distance apart from a floating rigid dock under regular and irregular waves.

Synthesis and Investigation of Bonding Scenario in a Bis(silaselenone)

European Journal of Inorganic Chemistry, EarlyView.
Silaselenones, the compounds containing Si=Se bond, are rarely reported in the literature. Silaselenones are the class of compounds that possess Si=Se bond. Herein, we report a bis(silaselenone) and we investigate nature of bonding between Si–Si atoms and Si—Amidinate moieties by employing Natural bond orbital (NBO), Quantum theory of atoms in ...

Scalp‐negative medial temporal interictal epileptic discharges alter large‐scale brain networks: A simultaneous high‐density electroencephalographic and intracranial electroencephalographic study

Epilepsia, EarlyView.
Abstract Objective Interictal epileptiform discharges (IEDs) observed on scalp electroencephalography (EEG) serve as a diagnostic hallmark of epilepsy. However, only a small fraction of IEDs recorded by intracranial EEG (iEEG) are detectable on the scalp; the vast majority remain invisible on scalp recordings.

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Perturbative solution of fermionic sign problem in quantum Monte Carlo computations

npj Computational Materials
We have developed a strong-coupling perturbation scheme for a general doped Hubbard model around a particle-hole-symmetric reference system, which is free from the fermionic sign problem.
