Quantum critical behavior in heavily doped LaFeAsO$_{1-x}$H$_x$ pnictide superconductors analyzed using nuclear magnetic resonance [PDF]
, 2015 We studied the quantum critical behavior of the second antiferromagnetic (AF) phase in the heavily electron-doped high-$T_c$ pnictide, LaFeAsO$_{1-x}$H$_x$ by using $^{75}$As and $^{1}$H nuclear-magnetic-resonance (NMR) technique. In the second AF phase,

The Excitation Spectrum of a Bose-Einstein Condensate
, 2001 We report the first measurement of the excitation spectrum and the static structure factor of a Bose-Einstein condensate. The excitation spectrum displays a linear phonon regime, as well as a parabolic single-particle regime.

Two-versus one photon excitation laser scanning microscopy : Critical importance of excitation wavelength [PDF]
Frontiers in Bioscience, 2007 It is often anticipated that two-photon excitation (TPE) laser scanning microscopy should improve cell survival and tissue penetration relative to conventional one-photon excitation (OPE) confocal scanning laser microscopy (CLSM). However few studies have directly compared live cell imaging using one- vs two-photon laser scanning microscopy.

Predicting critical ignition in slow-fast excitable models
Physical Review E, 2020 Linearization around unstable travelling waves in excitable systems can be used to approximate strength-extent curves in the problem of initiation of excitation waves for a family of spatially confined perturbations to the rest state. This theory relies on the knowledge of the unstable travelling wave solution as well as the leading left and right ...

Field-tuned spin excitation spectrum of kπ skyrmion
New Journal of Physics, 2019 We study spin wave excitation modes of kπ skyrmion ( k = 1, 2, 3) in a magnetic nanodot under an external magnetic field along the z direction using micromagnetic simulations based on the Landau–Lifshitz–Gilbert equation. We find that a transition of kπ

Mutual stabilization of charge-density-wave and monoclinic distortion in sulfur at high pressures
Physical Review Research, 2023 The charge-density-wave (CDW) amplitude mode of the high-pressure sulfur-IV phase is observed between 83 and 146 GPa using Raman spectroscopy. The energy of this excitation softens with pressure yet remains finite at ν_{CDW}>100cm^{−1} up to the critical
