Recent Work<\/span><\/strong><\/h4>\n
1.\u00a0 Optically-Induced Faraday-Goldstone Waves<\/a><\/strong><\/div>\n
<\/div>\n
Faraday waves, typically observed in driven fluids, result from the confluence of nonlinearity and parametric amplification. We show that optical pulses can generate analogous phenomena that persist s<\/span>uch longer than the pump time-scales in ordered quantum solids. We present a theory of ultrafast light-matter interactions within a symmetry-broken state; dynamical nonlinear coupling between the Higgs (amplitude) and the Goldstone <\/span>(phase) modes drives an emergent phason texture that oscillates in space and in time: Faraday-Goldstone waves.<\/span><\/div>\n

2. Quantum order by disorder in Frustrated Spin Nanotubes<\/a><\/strong><\/div>\n

\"\"<\/p>\n

Using an integrated computational-analytic approach, we have explored the possibility of an emergent phase transition in a 1 + 1 frustrated quantum system. Our mean-field estimate for the parameters of the quantum helical transition is in good agreement with the density matrix renormalization (DMRG) results. We also evaluate the entanglement spectrum and nonlocal string order parameters to characterize the topological character of the emergent helical phase.<\/p>\n

3.\u00a0 Spatiotemporal Order and Parametric Instabilities from First-Principles<\/a><\/strong><\/p>\n

Shaping crystal structure with light is an enduring goal of physics and materials engineering. Here we present calculations in candidate materials selected by symmetry that allow light-induced spatiotemporal parametric instabilities. We demonstrate a theoretical framework that includes a complete symmetry analysis of phonon modes that contribute to parametric instabilities across all non-centrosymmetric point groups, a detailed survey of the materials landscape and finally the computation of nonlinear couplings from first principles. We then showcase detailed results for chiral crystals, ferroelectrics, and layered van der Waals materials. Our results pave the way towards realizing designer time-crystalline order in quantum materials, detectable with time-resolved diffractive probes.<\/p>\n

4. Tunable Spatiotemporal Orders in Driven Insulators<\/a><\/strong><\/p>\n

We present a mechanism for light-induced ordering that\u00a0oscillates in space and in time with specific predictions for <\/span>experiment.\u00a0 This is a\u00a0 pathway to optically driven phase transitions in insulators that are in symmetry-broken states where the interplay of nonlinearity, parametric resonance and spatial dispersion results in spatiotemporal orderings.<\/span><\/p>\n

5. Observation of a Critical Charge Mode in a Strange Metal<\/a><\/strong><\/p>\n

Strange metals lie outside the conventional description of conducting behavior, and their charge dynamics are not accessible with conventional probes. Using a state-of-the-art technique, synchrotron-radiation-based Mossbauer spectroscopy, we have studied the longitudinal charge fluctuations of as particular strange metal phase as a function of temperature and pressure. Our results represent a direct observation of critical charge fluctuations as a new signature of strange metals.<\/p>\n
