Theory of symmetry-resolved quench-drive spectroscopy: Nonlinear response of phase-fluctuating superconductors
Matteo Puviani
Recent experiments on cuprates have shown the possibility of opening a gap above the superconducting critical temperature, in the so-called phase-fluctuating state, by enhancing th…
Tracing the dynamics of superconducting order via transient third harmonic generation
Min-Jae Kim, Sergey Kovalev, Mattia Udina +13
Ultrafast optical control of quantum systems is an emerging field of physics. In particular, the possibility of light-driven superconductivity with ultrashort laser pulses has attr…
Quench-drive spectroscopy of cuprates
Matteo Puviani, Dirk Manske
Cuprates are d-wave superconductors which exhibit a rich phase diagram: they are characterized by superconducting fluctuations even above the critical temperature, and thermal diso…
Fano interference of the Higgs mode in cuprate high-Tc superconductors
Hao Chu, Sergey Kovalev, Zi Xiao Wang +31
Despite decades of search for the pairing boson in cuprate high-Tc superconductors, its identity still remains debated to date. For this reason, spectroscopic signatures of electro…
Calculation of an enhanced A1g symmetry mode induced by Higgs oscillations in the Raman spectrum of high-temperature cuprate superconductors
M. Puviani, A. Baum, S. Ono +3
In superconductors the Anderson-Higgs mechanism allows for the existence of a collective amplitude (Higgs) mode which can couple to eV-light mainly in a non-linear Raman-like proce…
Current-assisted Raman activation of the Higgs mode in superconductors
Matteo Puviani, Lukas Schwarz, Xiao-Xiao Zhang +2
The Higgs mode in superconductors is a scalar mode without electric or magnetic dipole moment. Thus, it is commonly believed that its excitation is restricted to a nonlinear two-ph…
Quantum nonlinear phononics route towards nonequilibrium materials engineering: Melting dynamics of a ferrielectric charge density wave
M. Puviani, M. A. Sentef
Negative nonlinear electron-phonon coupling involving an infrared-active phonon mode can lead to an instability towards the formation of a polar lattice distortion with ferrielectr…
Dynamics and Control of Edge States in Laser-driven Graphene Nanoribbons
Matteo Puviani, Franca Manghi, Andrea Bertoni
An intense laser field in the high-frequency regime drives carriers in graphene nanoribbons (GNRs) out of equilibrium and creates topologically-protected edge states. Using Floquet…
Time evolution of Floquet states in graphene
Franca Manghi, Matteo Puviani, Francesco Lenzini
Based on a solution of the Floquet Hamiltonian we have studied the time-evolution of electronic states in graphene nanoribbons driven out of equilibrium by time-dependent electroma…
Periodically driven interacting electrons in 1D: a many-body Floquet approach
M. Puviani, F. Manghi
We propose a method to study the time evolution of correlated electrons driven by an harmonic perturbation. Combining Floquet formalism to include the time-dependent field and Clus…
