Edge State, Band Topology, and Time Boundary Effect in the Fine-Grained Categorization of Chern Insulators
H. C. Wu, H. S. Xu, L. C. Xie +1
We predict novel topological phases with broken time-reversal symmetry supporting the coexistence of opposite chiral edge states, which are fundamentally different from the photoni…
Magnetic structure and Kondo lattice behavior in CeVGe: an NMR and neutron scattering study
C. Chaffey, H. C. Wu, Hanshang Jin +9
We present nuclear magnetic resonance (NMR), neutron diffraction, magnetization, and transport measurements on a single crystal and powder of CeVGe. This material exhibits heav…
Topology of anti-parity-time-symmetric non-Hermitian Su-Schrieffer-Heeger model
H. C. Wu, L. Jin, Z. Song
We propose an anti-parity-time (anti-PT ) symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model, where the large non-Hermiticity constructively creates nontrivial topology and g…
Inversion symmetric non-Hermitian Chern insulator
H. C. Wu, L. Jin, Z. Song
We propose a two-dimensional non-Hermitian Chern insulator with inversion symmetry, which is anisotropic and has staggered gain and loss in both x and y directions. In this system,…
Topological Phase Transition Independent of System Non-Hermiticity
K. L. Zhang, H. C. Wu, L. Jin +1
Non-Hermiticity can vary the topology of system, induce topological phase transition, and even invalidate the conventional bulk-boundary correspondence. Here, we show the introduci…
Relativistic light synthesis of femtosecond sawtooth pulses
K. Hu, H. -C. Wu
Formation of femtosecond sawtooth pulses by high harmonic generation from relativistic oscillating mirrors is studied. For oblique incidence of -polarized laser pulse, one can e…
An explanation of trans-ionospheric pulse pairs
H. -C. Wu
Trans-ionospheric pulse pairs are the most powerful natural radio signals on the Earth and associated with lightning. They have been discovered for two decades by satellites, but t…
Antisite disorder driven spontaneous exchange bias effect in La2-xSrxCoMnO6 (0<x<1)
J. Krishna Murthy, K. D. Chandrasekhar, H. C. Wu +3
Doping at the rare-earth site by divalent alkaline-earth ions in perovskite lattice has witnessed a variety of magnetic and electronic orders with spatially correlated charge, spin…
Theory of ball lightning
H. -C. Wu
We present a comprehensive theory on the formation of ball lightning, a luminous sphere sometimes observed after normal lightning. In a ball lightning event, a relativistic electro…
Metamagnetic behavior and effect of field cooling on sharp magnetization jumps in multiferroic Y2CoMnO6
J. Krishna Murthy, K. Devi Chandrasekhar, H. C. Wu +3
We present sharp magnetization jumps and field induced irreversibility in magnetization in multiferroic Y2CoMnO6. Appearance of magnetic relaxation and field sweep rate dependence…
Scaling of laser-driven ion energies in the relativistic transparent regime
D. Jung, L. Yin, B. J. Albright +12
Laser-driven ions have compelling properties and their potential use for medical applications has attracted a huge global interest. One of the major challenges of these application…
160 MeV laser-accelerated protons from CH2 nano-targets for proton cancer therapy
B. M. Hegelich, D. Jung, B. J. Albright +11
Proton (and ion) cancer therapy has proven to be an extremely effective even supe-rior method of treatment for some tumors 1-4. A major problem, however, lies in the cost of the pa…
Laser-driven collimated tens-GeV monoenergetic protons from mass-limited target plus preformed channel
F. L. Zheng, S. Z. Wu, H. C. Wu +5
Proton acceleration by ultra-intense laser pulse irradiating a target with cross-section smaller than the laser spot size and connected to a parabolic density channel is investigat…
Giant half-cycle attosecond pulses
H. -C. Wu, J. Meyer-ter-Vehn
Half-cycle picosecond pulses have been produced from thin photo-conductors, when applying an electric field across the surface and switching on conduction by a short laser pulse. T…
