Exact new mobility edges between critical and localized states
Xin-Chi Zhou, Yongjian Wang, Ting-Fung Jeffrey Poon +2
The disorder systems host three types of fundamental quantum states, known as the extended, localized, and critical states, of which the critical states remain being much less expl…
Two dimensional vertex-decorated Lieb lattice with exact mobility edges and robust flat bands
Yucheng Wang, Long Zhang, Yuhao Wan +2
The mobility edge (ME) that marks the energy separating extended and localized states is a central concept in understanding the metal-insulator transition induced by disordered or…
Nonlinear transport due to magnetic-field-induced flat bands in the nodal-line semimetal ZrTe5
Yongjian Wang, Thomas Boemerich, Jinhong Park +4
The Dirac material ZrTe at very low carrier density was recently found to be a nodal-line semimetal, where ultra-flat bands are expected to emerge in magnetic fields parallel t…
Exact mobility edges for 1D quasiperiodic models
Yongjian Wang, Xu Xia, Jiangong You +2
Mobility edges (ME), i.e. critical energies which separate absolutely continuous spectrum and purely point spectrum, is an important issue in quantum physics. So far there are two…
Exact non-Hermitian mobility edges in one-dimensional quasicrystal lattice with exponentially decaying hopping and its dual lattice
Yanxia Liu, Yongjian Wang, Zuohuan Zheng +1
We analytically determine the non-Hermitian mobility edges of a one-dimensional quasiperiodic lattice model with exponential decaying hopping and complex potentials as well as its…
Duality between two generalized Aubry-Andre models with exact mobility edges
Yucheng Wang, Xu Xia, Yongjian Wang +2
A mobility edge (ME) in energy separating extended from localized states is a central concept in understanding various fundamental phenomena like the metal-insulator transition in…
Gigantic magnetochiral anisotropy in the topological semimetal ZrTe5
Yongjian Wang, Henry F. Legg, Thomas Boemerich +6
Topological materials with broken inversion symmetry can give rise to nonreciprocal responses, such as the current rectification controlled by magnetic fields via magnetochiral ani…
Coexistence of zero Lyapunov exponent and positive Lyapunov exponent for new quasi-periodic Schrdinger operator
Yongjian Wang, Zuohuan Zheng
In this paper we solve a problem about the Schrdinger operator with potential in physics. With the help of the formula of Lyapunov e…
Calorimetric Evidence for a Fulde-Ferrell-Larkin-Ovchinnikov Superconducting State in the Layered Organic Superconductor κ_2_2$
R. Lortz, Y. Wang, A. Demuer +5
The specific heat of the layered organic superconductor -% (BEDT-TTF)Cu(NCS), where BEDT-TTF is bisethylenedithio-% tetrathiafulvalene, has been studied in magnetic fiel…
