Sum rules and density-wave modes in spin-singlet fractional quantum Hall fluids
Ritajit Kundu, Rakesh K. Dora, Dung Xuan Nguyen +1
Fractional quantum Hall (FQH) states are prototypical examples of strongly interacting topologically ordered systems. In this work, we obtain thermodynamic fits on the plane for th…
Band Inversion Flips the Winding of Bound States in the Continuum
Paul Bouteyre, Dung Xuan Nguyen, Loïc Malgrey +10
Bound states in the continuum (BICs) in photonic slabs and metasurfaces appear as polarization singularities in momentum space, characterized by an integer winding number. This win…
Topological Lasing from Thouless Pumping in Bilayer Photonic Crystal
D. -H. -Minh Nguyen, Dung Xuan Nguyen, Hai-Chau Nguyen +5
Topological lasing leverages concepts from topological physics to achieve single-mode light amplification within topological bandgaps, offering robustness against fabrication imper…
Spin of fractional quantum Hall neutral modes and "missing states" on a sphere
Dung Xuan Nguyen, Dam Thanh Son
A low-energy neutral quasiparticle in a fractional quantum Hall system appears in the latter's energy spectrum on a sphere as a series of many-body excited states labeled by the an…
