Quantum control of Hubbard excitons
D. R. Baykusheva, D. P. Carmichael, C. S. Weber +12
Quantum control of the many-body wavefunction is a central challenge in quantum materials research, as it could yield a precise control knob to manipulate emergent phenomena. Floqu…
Electronic layer decoupling driven by density-wave order in LaNiO
Ziqiang Guan, Sophia F. R. TenHuisen, M. Tepie +14
We probe the density-wave transition of the trilayer nickelate LaNiO with polarization-resolved infrared spectroscopy. The low-energy electrodynamics is strongly ani…
A light-induced charge order mode in a metastable cuprate ladder
Hari Padma, Prakash Sharma, Sophia F. R. TenHuisen +17
We report the observation of an emergent charge order mode in the optically-excited cuprate ladder SrCuO. Near-infrared light in the ladder plane drives a symm…
Photoinduced Frustration Modulation in -type Quantum Spin Liquid Candidates
M. Tepie, F. Glerean, J. Ovčar +7
Geometric frustration is a key parameter controlling electronic and magnetic properties of quantum spin liquid systems, yet remains challenging to tune. Here, we coherently drive m…
Symmetry-protected electronic metastability in an optically driven cuprate ladder
Hari Padma, Filippo Glerean, Sophia F. R. TenHuisen +23
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales…
Ultrafast pump-probe phase-randomized tomography
Filippo Glerean, Enrico Maria Rigoni, Giacomo Jarc +6
Measuring fluctuations in matter's low energy excitations is the key to unveil the nature of the nonequilibrium response of materials. A promising outlook in this respect is offere…
Dynamics of non-thermal states in optimally-doped revealed by mid-infrared three-pulse spectroscopy
Angela Montanaro, Enrico Maria Rigoni, Francesca Giusti +13
In the cuprates, the opening of a d-wave superconducting (SC) gap is accompanied by a redistribution of spectral weight at energies two orders of magnitude larger than this gap. Th…
Transient measurement of phononic states with covariance-based stochastic spectroscopy
G. Sparapassi, S. M. Cavaletto, J. Tollerud +6
We present a novel approach to transient Raman spectroscopy, which combines stochastic probe pulses and a covariance-based detection to measure stimulated Raman signals in alpha-qu…
Tunable cryogenic THz cavity for strong light-matter coupling in complex materials
Giacomo Jarc, Shahla Yasmin Mathengattil, Francesca Giusti +8
We report here the realization and commissioning of an experiment dedicated to the study of the optical properties of light matter hybrids constituted of crystalline samples embedd…
Non-adiabatic suppression of 3D excitonic screening in black phosphorus by mid-infrared pulses
Angela Montanaro, Francesca Giusti, Matteo Zanfrognini +10
The competition between the electron-hole Coulomb attraction and the three-dimensional dielectric screening dictates the optical properties of layered semiconductors. In low-dimens…
Anisotropic Time-Domain Electronic Response in Cuprates
Francesca Giusti, Angela Montanaro, Alexandre Marciniak +9
Superconductivity in the cuprates is characterized by spatial inhomogeneity and an anisotropic electronic gap of d-wave symmetry. The aim of this work is to understand how this ani…
Visible pump -- mid infrared pump -- broadband probe: development and characterization of a three-pulse setup for single-shot ultrafast spectroscopy at 50 kHz
Angela Montanaro, Francesca Giusti, Matija Colja +10
We report here an experimental setup to perform three-pulse pump-probe measurements over a wide wavelength and temperature range. By combining two pump pulses in the visible (650-9…
Time-resolved multimode heterodyne detection for dissecting coherent states of matter
Filippo Glerean, Giacomo Jarc, Alexandre Marciniak +6
Unveiling and controlling the coherent evolution of low energy states is a key to attain light driven new functionalities of materials. Here we investigate the coherent evolution o…
Vibrational coherent control of localized d-d electronic excitation
Alexandre Marciniak, Stefano Marcantoni, Francesca Giusti +10
Addressing the role of quantum coherence in the interplay between the different matter constituents (electrons, phonons and spin) is a critical step towards understanding transitio…
Femtosecond Covariance Spectroscopy
J. Tollerud, G. Sparapassi, A. Montanaro +9
The success of non-linear optics relies largely on pulse-to-pulse consistency. In contrast, covariance based techniques used in photoionization electron spectroscopy and mass spect…
