We present measurements of thermally generated transverse spin currents in the topological insulator Bi_{2}Se_{3}, thereby completing measurements of interconversions among the full triad of thermal gradients, charge currents, and spin currents. We accomplish this by comparing the spin Nernst magnetothermopower to the spin Hall magnetoresistance for bilayers of Bi_{2}Se_{3}/CoFeB. We find that Bi_{2}Se_{3}does generate substantial thermally driven spin currents. A lower bound for the ratio of spin current density to thermal gradient is

The measured emission lifetimes of the${}^{4}{\mathrm{I}}_{9/2}$ state were nearly independent of the temperature, indicating a negligibly small nonradiative decay rate through multiphonon relaxation, as predicted by the energygap law for lowmaximumphonon energy hosts.

The results of Judd–Ofelt analysis are presented and discussed. 
Abstract Broken symmetries in topological condensed matter systems have implications for the spectrum of Fermionic excitations confined on surfaces or topological defects. The Fermionic spectrum of confined (quasi2D)^{3}HeA consists of branches of chiral edge states. The negative energy states are related to the groundstate angular momentum,
, for ${L}_{z}=(N/2)\hslash $ Cooper pairs. The power law suppression of the angular momentum, $N/2$ for ${L}_{z}(T)\simeq (N/2)\hslash [1\frac{2}{3}(\pi T/\mathrm{\Delta}{)}^{2}]$ , in the fully gapped 2D chiral Aphase reflects the thermal excitation of the chiral edge Fermions. We discuss the effects of wave function overlap, and hybridization between edge states confined near opposing edge boundaries on the edge currents, groundstate angular momentum and groundstate order parameter of superfluid^{3}He thin films. Under strong lateral confinement, the chiral A phase undergoes a sequence of phase transitions, first to a pair density wave (PDW) phase with broken translational symmetry at $0\u2a7dT\ll {T}_{c}$ . The PDW phase is described by a periodic array of chiral domains with alternating chirality, separated by domain walls. The period of PDW phase diverges as the confinement length ${D}_{c2}\sim 16{\xi}_{0}$ . The PDW phase breaks timereversal symmetry, translation invariance, but is invariant under the combination of timereversal and translation by a onehalf period of the PDW. The mass current distribution of the PDW phase reflects this combined symmetry, and originates from the spectra of edge Fermions and the chiral branches bound to the domain walls. Under sufficiently strong confinement a secondorder transition occurs to the nonchiral ‘polar phase’ at $D\to {D}_{{c}_{2}}$ , in which a single pwave orbital state of Cooper pairs is aligned along the channel. ${D}_{c1}\sim 9{\xi}_{0}$ 
Abstract The genericity of Arnold diffusion in the analytic category is an open problem. In this paper, we study this problem in the following
a priori unstable Hamiltonian system with a timeperiodic perturbation where ${\mathcal{H}}_{\epsilon}(p,q,I,\phi ,t)=h(I)+\sum _{i=1}^{n}\pm \left(\frac{1}{2}{p}_{i}^{2}+{V}_{i}({q}_{i})\right)+\epsilon {H}_{1}(p,q,I,\phi ,t),$ , $(p,q)\in {\mathbb{R}}^{n}\times {\mathbb{T}}^{n}$ with $(I,\phi )\in {\mathbb{R}}^{d}\times {\mathbb{T}}^{d}$n ,d ⩾ 1,V _{i}are Morse potentials, andɛ is a small nonzero parameter. The unperturbed Hamiltonian is not necessarily convex, and the induced inner dynamics does not need to satisfy a twist condition. Using geometric methods we prove that Arnold diffusion occurs for generic analytic perturbationsH _{1}. Indeed, the set of admissibleH _{1}isC ^{ω}dense andC ^{3}open (a fortiori ,C ^{ω}open). Our perturbative technique for the genericity is valid in theC ^{k}topology for allk ∈ [3, ∞) ∪ {∞,ω }. 
Tracing a resonance frequency of a high quality factor (
Q ) optical cavity facilitates subpicometer displacement measurements of the optical cavity via Pound–Drever–Hall (PDH) locking scheme, tightly synchronizing a laser frequency to the optical cavity. Here we present observations of subfemtometer displacements on a ultrahighQ singlecrystal${\mathrm{MgF}}_{2}$ whisperinggallerymode microcavity by frequency synchronization between a 1 Hz cavitystabilized laser and a resonance of the${\mathrm{MgF}}_{2}$ cavity using PDH lasercavity locking. We characterize not only the displacement spectral density of the microcavity with a sensitivity of$1.5\times {10}^{16}\text{\hspace{0.17em}\hspace{0.17em}}\mathrm{m}/{\mathrm{Hz}}^{1/2}$ over the Fourier offset frequency ranging from 15 mHz to 100 kHz but also a 1.77 nm displacement fluctuation of the microcavity over 4500 s. Such measurement capability not only supports the analysis of integrated thermodynamical and technical cavity noise but allows for minute displacement measurements using lasercavity locking for ultraprecise positioning, metrology, and sensing. 
Abstract We have observed electron impact fluorescence from CO_{2}to excite the Cameron bands (CBs), CO (
a ^{3}Π →X ^{1}Σ^{+}; 180–280 nm), the firstnegative group (1NG) bands, CO^{+}(B ^{2}Σ^{+}→X ^{2}Σ^{+}; 180–320 nm), the fourthpositive group (4PG) bands, CO (A ^{1}Π →X ^{1}Σ^{+}; 111–280 nm), and the UV doublet, CO_{2}^{+}( 288.3 and 289.6 nm) in the ultraviolet (UV). This wavelength range matches the spectral region of past and present spacecraft equipped to observe UV dayglow and aurora emissions from the thermospheres (100–300 km) of Mars and Venus. Our large vacuum system apparatus is able to measure the emission cross sections of the strongest optically forbidden UV transitions found in planetary spectra. Based on our crosssectional measurements, previous CB emission crosssectional errors exceed a factor of 3. The UV doublet lifetime is perturbed through $\tilde{B}{\phantom{\rule{0.33em}{0ex}}}^{2}{\mathrm{\Sigma}}_{u}^{+}\to \tilde{X}{\phantom{\rule{0.33em}{0ex}}}^{2}{\mathrm{\Pi}}_{g};$ spin–orbit coupling. Forward modeling codes of the Mars dayglow have not been accurate in the midUV due to systematic errors in these two emission cross sections. We furnish absolute emission cross sections for several band systems over electron energies 20–100 eV for CO_{2}. We present a CB lifetime, which together with emission cross sections, furnish a set of fundamental physical constants for electron transport codes such as AURIC (Atmospheric Ultraviolet Radiance Integrated Code). AURIC and TransMars are used in the analysis of UV spectra from the Martian dayglow and aurora. $\tilde{B}{\phantom{\rule{0.33em}{0ex}}}^{2}{\mathrm{\Sigma}}_{u}^{+}\tilde{A}{\phantom{\rule{0.33em}{0ex}}}^{2}{\mathrm{\Pi}}_{u}$
