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 the decay product of the Higgs boson, i.e., the scalar (amplitude) excitation of the Higgs field. In superconductors, Cooper pairs bear a close analogy to the Higgs field. Interaction between the Cooper pairs and other degrees of freedom provides dissipation channels for the amplitude mode, which may reveal important… 
Theory of driven Higgs oscillations and third-harmonic generation in unconventional superconductors
Higgs spectroscopy is a new field in which Higgs modes in nonequilibrium superconductors are analyzed to gain information about the ground state. One experimental setup in which the Higgs mode in
Light quantum control of persisting Higgs modes in iron-based superconductors
A tunable coherent amplitude oscillation of the order parameter in Ba(Fe 1− x Co x ) 2 As 2 is observed, suggesting appearance and control of the Higgs mode by light tuning interband interaction, and can be extended to probe many-body entanglement and hidden symmetries in other complex systems.
Anomalous Higgs oscillations mediated by Berry curvature and quantum metric
Higgs spectroscopy, the study of Higgs bosons of a superconductor, is an emerging field in studying superconductivity. Here we show that the Berry curvature and the quantum metric of bands play a
Phase signatures in the third-harmonic response of Higgs and coexisting modes in superconductors
Third-harmonic generation (THG) experiments on superconductors can be used to investigate collective excitations like the amplitude mode of the order parameter known as Higgs mode. These modes are

By applying a microscopic gauge-invariant kinetic theory in $d$-wave superconductors, we analytically derive the energy spectra of the breathing Higgs mode and, in particular, rotating Higgs mode
Enhanced A1g Raman response in cuprates due to Higgs oscillations.
In superconductors the Anderson-Higgs mechanism allows for the existence of a collective amplitude (Higgs) mode which can couple to light only in a non-linear Raman-like process. While the observed
Higgs mode stabilization by photoinduced long-range interactions in a superconductor
We show that low-lying excitations of a 2D BCS superconductor are significantly altered when coupled to an externally driven cavity, which induces controllable long-range attractive interactions
Higgs-mode resonance in third harmonic generation in NbN superconductors: Multiband electron-phonon coupling, impurity scattering, and polarization-angle dependence
We theoretically investigate the resonance of third harmonic generation (THG) that has been observed at frequency being half of the superconducting gap in a multiband disordered superconductor NbN.
Time-resolved optical conductivity and Higgs oscillations in two-band dirty superconductors

Higgs time crystal in a high- Tc superconductor
We propose to induce a time crystalline state in a high-$T_c$ superconductor, by optically driving a sum resonance of the Higgs mode and a Josephson plasma mode. The generic cubic process that

Coupling of Higgs and Leggett modes in non-equilibrium superconductors
Using numerical exact simulations, it is shown that optical pump–probe experiments excite both Higgs and Leggett modes out of equilibrium, and that this non-adiabatic excitation process introduces a strong interaction between the collective modes, which is absent in equilibrium.

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

Light-induced collective pseudospin precession resonating with Higgs mode in a superconductor
The method presented here paves a way toward nonlinear quantum optics in superconductor with driving the pseudospins collectively and can be potentially extended to exotic superconductors for shedding light on the character of order parameters and their coupling to other degrees of freedom.
Nonrelativistic Dynamics of the Amplitude (Higgs) Mode in Superconductors.
This work investigates the fate of the Higgs mode in the unconventional case where 2E_{gap} becomes larger than 2Δ_{0}, as due to strong coupling or strong disorder, and shows that in this situation, the amplitude fluctuations never identify a real mode, since such a "bosonic" limit is always reached via strong mixing with the phase fluctuations, which dominate the low-energy part of the spectrum.
