In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

When the continuous symmetry of a physical system is spontaneously broken, two types of
collective modes typically emerge: the amplitude and the phase modes of the order …

Superconductors host collective modes that can be manipulated with light. We show that a
strong terahertz light field can induce oscillations of the superconducting order parameter in …

Strong optical pulses at mid-infrared and terahertz frequencies have recently emerged as
powerful tools to manipulate and control the solid state and especially complex condensed …

Light-induced supercurrents chart a path forward for the electromagnetic design of emergent
materials phases and collective modes for quantum engineering applications. However …

In high-energy physics, the Higgs field couples to gauge bosons and fermions and gives
mass to their elementary excitations. Experimentally, such couplings can be inferred from …

We investigate the terahertz (THz)-pulse-driven nonlinear response in the d-wave cuprate
superconductor Bi 2 Sr 2 CaCu 2 O 8+ x (Bi2212) using a THz pump near-infrared probe …

Abstract In conventional Bardeen–Cooper–Schrieffer superconductors, electrons with
opposite momenta bind into Cooper pairs due to an attractive interaction mediated by …

A superconductor illuminated by an ac electric field with frequency Ω is theoretically found to
generate a collective precession of Anderson's pseudospins, and hence a coherent …

We investigate the dynamics of a phonon-mediated superconductor driven out of
equilibrium. The electronic hop** amplitude is ramped down in time, resulting in an …
