Revealing the anisotropic charge-density-wave order of TiSe through high harmonic generation
Lin Zhang, Igor Tyulnev, Lenard Vamos +6
Titanium diselenide (TiSe) is a transition-metal dichalcogenide material that undergoes a charge-density-wave (CDW) transition at . In a recent…
High harmonic spectroscopy reveals anisotropy of the Mott to Charge-Density-Wave phase transition in TiSe
Igor Tyulnev, Lin Zhang, Lenard Vamos +8
This work explores the use of polarization-resolved high harmonic generation (HHG) spectroscopy to investigate the quantum phases and transitions in the correlated charge density w…
Probing spontaneously symmetry-broken phases with spin-charge separation through noise correlation measurements
Kerman Gallego-Lizarribar, Sergi Julià-Farré, Maciej Lewenstein +3
Spontaneously symmetry-broken (SSB) phases are locally ordered states of matter characterizing a large variety of physical systems. Because of their specific ordering, their presen…
Introduction to quantum entanglement in many-body systems
Anubhav Kumar Srivastava, Guillem Müller-Rigat, Maciej Lewenstein +1
The quantum mechanics formalism introduced new revolutionary concepts challenging our everyday perceptions. Arguably, quantum entanglement, which explains correlations that cannot…
Topological quantum thermometry
Anubhav Kumar Srivastava, Utso Bhattacharya, Maciej Lewenstein +1
An optimal local quantum thermometer is a quantum many-body system that saturates the fundamental lower bound for the thermal state temperature estimation accuracy [L. Correa, et.…
Competing order in two-band Bose-Hubbard chains with extended-range interactions
Yuma Watanabe, Utso Bhattacharya, Ravindra W. Chhajlany +3
Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the cas…
Above threshold ionization by few-cycle spatially inhomogeneous fields
M. F. Ciappina, J. A. Pérez-Hernández, T. Shaaran +3
We present theoretical studies of above threshold ionization (ATI) produced by spatially inhomogeneous fields. This kind of field appears as a result of the illumination of plasmon…
Tailoring high-order harmonic generation with nonhomogeneous fields and electron confinement
M. F. Ciappina, Srdjan S. Acimovic, T. Shaaran +3
We study high-order harmonic generation (HHG) resulting from the illumination of plasmonic nanostructures with a short laser pulse. We show that both the inhomogeneities of the loc…
High-order harmonic generation from inhomogeneous fields
M. F. Ciappina, J. Biegert, R. Quidant +1
We present theoretical studies of high-order harmonic generation (HHG) produced by non-homogeneous fields as resulting from the illumination of plasmonic nanostructures with a shor…
