Quantum metric quadrupoles in elemental bismuth thin films
Rhonald Burgos Atencia, Pavlo Makushko, Gabriele Naselli +11
The nonlinear transport properties of solids are deeply rooted in the quantum geometry of their electronic wavefunctions, which is encoded in the quantum geometric tensor. Its real…
Soliton Pumping in the Rice-Mele Model with On-Cell Kerr Nonlinearity
Zhe Wang, Xi-Wang Luo, Bo-Ye Sun +1
We investigate the Rice-Mele model with on-cell Kerr-type nonlinearities, where the interaction depends on the total particle number within each unit cell rather than on individual…
Quantum criticality with emergent symmetry in the extended Shastry-Sutherland model
Wen-Yuan Liu, Xiao-Tian Zhang, Zhe Wang +3
Motivated by the novel phenomena observed in the layered material , the Shastry-Sutherland model (SSM) has been extensively studied as the minimal model for $\r…
Ellipticity control of terahertz high-harmonic generation in a Dirac semimetal
Semyon Germanskiy, Renato M. A. Dantas, Sergey Kovalev +9
We report on terahertz high-harmonic generation in a Dirac semimetal as a function of the driving-pulse ellipticity and on a theoretical study of the field-driven intraband kinetic…
High-order nonlinear terahertz probing of the two-band superconductor MgB: Third- and fifth-order harmonic generation
C. Reinhoffer, P. Pilch, A. Reinold +16
We report on high-order harmonic generation in the two-band superconductor MgB driven by intense terahertz electromagnetic pulses. Third- and fifth-order harmonics are resolved…
Band-selective third-harmonic generation in superconducting MgB: Possible evidence for Higgs amplitude mode in the dirty limit
Sergey Kovalev, Tao Dong, Li-Yu Shi +13
We report on time-resolved linear and nonlinear terahertz spectroscopy of the two-band superconductor MgB with the superconducting transition temperature K. Th…
Relaxation dynamics of the optically driven nonequilibrium states in the electron- and hole-doped topological-insulator materials
Chris Reinhoffer, Yu Mukai, Semyon Germanskiy +7
We report on time-resolved mid-infrared-pump terahertz-transmission-probe studies of the topological-insulator materials , in which by varying x charge…
Nonperturbative Topological Current in Weyl and Dirac Semimetals in Laser Fields
Renato M. A. Dantas, Zhe Wang, Piotr Surówka +1
We study non-perturbatively the anomalous Hall current and its high harmonics generated in Weyl and Dirac semimetals by strong elliptically polarized laser fields, in the context o…
Non-perturbative high-harmonic generation in the three-dimensional Dirac semimetal CdAs
Sergey Kovalev, Renato M. A. Dantas, Semyon Germanskiy +12
Harmonic generation is a general characteristic of driven nonlinear systems, and serves as an efficient tool for investigating the fundamental principles that govern the ultrafast…
Phase-resolved Higgs response in superconducting cuprates
Hao Chu, Min-Jae Kim, Kota Katsumi +26
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…
Magnetic field dependence of antiferromagnetic resonance in NiO
Zhe Wang, S. Kovalev, N. Awari +7
We report on measurements of magnetic field and temperature dependence of antiferromagnetic resonances in the prototypical antiferromagnet NiO. The frequencies of the magnetic reso…
