Hole dynamics in a quantum antiferromagnet beyond the retraceable path approximation

, 1993
The one-hole spectral weight for two chains and two dimensional lattices is studied numerically using a new method of analysis of the spectral function within the Lanczos iteration scheme: the Lanczos spectra decoding method. This technique is applied to

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.

Stochastic Lanczos estimation of genomic variance components for linear mixed-effects models

BMC Bioinformatics, 2019
Background Linear mixed-effects models (LMM) are a leading method in conducting genome-wide association studies (GWAS) but require residual maximum likelihood (REML) estimation of variance components, which is computationally demanding. Previous work has

The Impact of OCO‐2 Seasonally Dependent Sampling on Carbon Flux Estimation in the Northern Tropical Africa

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The large annual carbon source over northern tropical Africa (NTA), inferred from satellite CO2, remains highly debated. Using observing system simulation experiments with Orbiting Carbon Observatory‐2 (OCO‐2) sampling, we show that seasonally dependent sampling can lead to overestimated annual fluxes.

Inflationary power spectrum from the Lanczos algorithm

European Physical Journal C: Particles and Fields
The generalized Lanczos algorithm can provide a universal method for constructing a wave function under the the Hamiltonian group structure. Based on this fact, we obtain an open two-mode squeezed state as the quantum origin for the curvature ...

Changes in MJO Teleconnections in the Southeast U.S. Under Global Warming in the CESM2 Large Ensemble

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We examined projected changes in Madden–Julian Oscillation (MJO) teleconnections over North America using 90 ensemble members from the Community Earth System Model Version 2 Large Ensemble (CESM‐LENS2) under the SSP370 scenario. In the warmer climate, the classic PNA‐like teleconnection strengthens and shifts eastward, with large ensemble ...

Probing Krylov complexity in scalar field theory with general temperatures

Journal of High Energy Physics
Krylov complexity characterizes the operator growth in the quantum many-body systems or quantum field theories. The existing literatures have studied the Krylov complexity in the low temperature limit in the quantum field theories.
