Magneto-elasto-resistivity in FeSe
M. Wissmann, L. Fanfarillo, X. -C. Hong +6
FeSe stands out among iron-based superconductors due to its extended nematic phase without the onset of long-range magnetic order. While strain-dependent electrical resistivity has…
Boosting superconductivity in ultrathin YBaCuO films via nanofaceted substrates
Eric Wahlberg, Riccardo Arpaia, Debmalya Chakraborty +7
In cuprate high-temperature superconductors the doping level is fixed during synthesis, hence the charge carrier density per CuO plane cannot be easily tuned by conventional ga…
Revealing novel aspects of light-matter coupling in terahertz two-dimensional coherent spectroscopy: the case of the amplitude mode in superconductors
Kota Katsumi, Jacopo Fiore, Mattia Udina +7
Recently developed terahertz (THz) two-dimensional coherent spectroscopy (2DCS) is a powerful technique to obtain materials information in a fashion qualitatively different from ot…
Investigating Josephson plasmons in layered cuprates via nonlinear terahertz spectroscopy
Jacopo Fiore, Niccolò Sellati, Francesco Gabriele +4
Josephson plasmons in layered superconductors represent a natural source of optical non-linearity, thanks to their intrinsically anharmonic nature. Here we derive the selection rul…
Contribution of Collective Excitations to Third Harmonic Generation in Multiband Superconductors: the case of MgB
Jacopo Fiore, Mattia Udina, Marco Marciani +2
Multiband superconductors can host collective excitations with marked differences with respect to their single-band counterpart. We first study the spectrum of collective amplitude…
THz non-linear optical response in cuprates: predominance of the BCS response over the Higgs mode
Mattia Udina, Jacopo Fiore, Tommaso Cea +3
Recent experiments with strong THz fields in unconventional cuprates superconductors have clearly evidenced an increase of the non-linear optical response below the superconducting…
Adiabatic transition from a BCS superconductor to a Fermi liquid and phase dynamics
G. Seibold, C. Castellani, J. Lorenzana
We investigate the physics of an adiabatic transition from a BCS superconductor to a Fermi liquid for an exponentially slow decreasing pairing interaction. In particular, we show t…
Phase separation and pairing fluctuations in oxide materials
A. Bill, V. Hizhnyakov, R. K. Kremer +3
We investigate the microscopic mechanism of charge instabilities and the formation of inhomogeneous states in systems with strong electron correlations. It is demonstrated that wit…
Third harmonic generation from collective modes in disordered superconductors
G. Seibold, M. Udina, C. Castellani +1
Recent experiments with strong THz fields in both conventional and unconventional superconductors have clearly evidenced a marked third-harmonic generation below the superconductin…
Restored strange metal phase through suppression of charge density waves in underdoped YBaCuO
E. Wahlberg, R. Arpaia, G. Seibold +10
The normal state of optimally doped cuprates is dominated by the "strange metal" phase that shows a linear temperature () dependence of the resistivity persisting down to the lo…
Non-equilibrium dynamics across the BEC-BCS crossover
G. Seibold, J. Lorenzana
We investigate the quench dynamics of strongly coupled superconductors within the time-dependent Gutzwiller approximation from the BCS to the BEC regime and evaluate the out-of-equ…
Formation of Incommensurate Charge Density Waves in Cuprates
H. Miao, R. Fumagalli, M. Rossi +8
Although charge density waves (CDWs) are omnipresent in cuprate high-temperature superconductors, they occur at significantly different wavevectors, confounding efforts to understa…
Strange metal behaviour from charge density fluctuations in cuprates
G. Seibold, R. Arpaia, Y. Y. Peng +6
Besides the mechanism responsible for high critical temperature superconductivity, the grand unresolved issue of the cuprates is the occurrence of a strange metallic state above th…
Phase separation and proximity effects in itinerant ferromagnet-superconductor heterostructures
Christian Martens, Andreas Bill, Götz Seibold
Heterostructures made of itinerant ferromagnets and superconductors are studied. In contrast to most previous models, ferromagnetism is not enforced as an external Zeeman field but…
On the application of Mattis-Bardeen theory in strongly disordered superconductors
G. Seibold, L. Benfatto, C. Castellani
The low energy optical conductivity of conventional superconductors is usually well described by Mattis-Bardeen (MB) theory which predicts the onset of absorption above an energy c…
High-temperature charge density wave correlations in LaBaCuO without spin-charge locking
H. Miao, J. Lorenzana, G. Seibold +11
Although all superconducting cuprates display charge-ordering tendencies, their low-temperature properties are distinct, impeding efforts to understand the phenomena within a singl…
Pseudogap and (an)isotropic scattering in the fluctuating charge-density wave phase of cuprates
S. Caprara, C. Di Castro, M. Grilli +1
We present a general scenario for high-temperature superconducting cuprates, based on the presence of dynamical charge density waves (CDWs) and to the occurrence of a CDW quantum c…
Dynamical charge density waves rule the phase diagram of cuprates
S. Caprara, C. Di Castro, G. Seibold +1
In the last few years charge density waves (CDWs) have been ubiquitously observed in high-temperature superconducting cuprates and are now the most investigated among the competing…
Electronic polymers and soft-matter-like broken symmetries in underdoped cuprates
M. Capati, S. Caprara, C. Di Castro +3
Empirical evidence in heavy fermion, pnictide, and other systems suggests that unconventional superconductivity appears associated to some form of real-space electronic order. For…

G. Seibold, L. Benfatto, C. Castellani +1
We investigate the disorder dependence of the static density, amplitude and current correlations within the attractive Hubbard model supplemented with on-site disorder. It is found…
Non-relativistic dynamics of the amplitude (Higgs) mode in superconductors
T. Cea, C. Castellani, G. Seibold +1
Despite the formal analogy with the Higgs particle, the amplitude fluctuations of the order parameter in weakly-coupled superconductors do not identify a real mode with a Lorentz-i…

R. S. Markiewicz, G. Seibold, J. Lorenzana +1
Besides significant electronic correlations, high-temperature superconductors also show a strong coupling of electrons to a number of lattice modes. Combined with the experimental…
