Bacteria under external stress can reveal unexpected emergent phenotypes. We show that the intensely studied bacterium
Ultrafast spectroscopies have become an important tool for elucidating the microscopic description and dynamical properties of quantum materials. In particular, by tracking the dynamics of nonthermal electrons, a material’s dominant scattering processes can be revealed. Here, we present a method for extracting the electronphonon coupling strength in the time domain, using time and angleresolved photoemission spectroscopy (TRARPES). This method is demonstrated in graphite, where we investigate the dynamics of photoinjected electrons at the

Escherichia coli can transform into long, highly motile helical filaments poized at a torsional buckling criticality when exposed to minimum inhibitory concentrations of several antibiotics. While the highly motile helices are physically either right or lefthanded, the motile helices always rotate with a righthanded angular velocity$\overrightarrow{\omega}$ , which points in the same direction as the translational velocity${\overrightarrow{v}}_{T}$ of the helix. Furthermore, these helical cells do not swim by a “run and tumble” but rather synchronously flip their spin$\overrightarrow{\omega}$ and thus translational velocity—backing upmore » 
We present exact results that give insight into how interactions lead to transport and superconductivity in a flat band where the electrons have no kinetic energy. We obtain bounds for the optical spectral weight for flatband superconductors that lead to upper bounds for the superfluid stiffness and the twodimensional (2D)
${T}_{c}$ . We focus on onsite attraction$\leftU\right$ on the Lieb lattice with trivial flat bands and on the πflux model with topological flat bands. For trivial flat bands, the lowenergy optical spectral weight${\stackrel{\u0303}{D}}_{\text{low}}\le \stackrel{\u0303}{n}\leftU\right\mathrm{\Omega}/2$ with$\stackrel{\u0303}{n}=min\left(n,2n\right)$ , where n is the flatband density and Ω is themore »

Sb$$_{0.16}$$ ${}_{0.16}$ multiplequantum well sample is investigated for the photoexcited carrier dynamics as a function of excitation photon energy and lattice temperature. Timeresolved measurements are performed using a nearinfrared pump pulse, with photon energies near to and above the band gap, probed with a terahertz probe pulse. The transient terahertz absorption is characterized by a multirise, multidecay function that captures longlived decay times and a metastable state for an excessphoton energy of$$_{0.84}$$ ${}_{0.84}$ meV. For sufficient excessphoton energy, excitation of the metastable state is followed by a transition to the longlived states. Excitation dependence of the longlived states map onto amore »$$>100$$ $>100$ 
We present an approach to understand geometricincompatibility–induced rigidity in underconstrained materials, including subisostatic 2D spring networks and 2D and 3D vertex models for dense biological tissues. We show that in all these models a geometric criterion, represented by a minimal length
${\overline{\ell}}_{min}$ , determines the onset of prestresses and rigidity. This allows us to predict not only the correct scalings for the elastic material properties, but also the precise magnitudes for bulk modulus and shear modulus discontinuities at the rigidity transition as well as the magnitude of the Poynting effect. We also predict from first principles that the ratio ofmore » 
Solar wind provides an example of a weakly collisional plasma expanding from a thermal source in the presence of spatially diverging magneticfield lines. Observations show that in the inner heliosphere, the electron temperature declines with the distance approximately as
${T}_{e}\left(r\right)\sim {r}^{0.3}\dots {r}^{0.7}$ , which is significantly slower than the adiabatic expansion law$\sim {r}^{4/3}$ . Motivated by such observations, we propose a kinetic theory that addresses the nonadiabatic evolution of a nearly collisionless plasma expanding from a central thermal source. We concentrate on the dynamics of energetic electrons propagating along a radially diverging magneticflux tube. Due to conservation of their magnetic moments, the electrons formmore »
