The pursuit of exotic phases of matter outside of the extreme conditions of a quantizing
magnetic field is a long-standing quest of solid state physics. Recent experiments have …

Among a huge variety of known two-dimensional (2D) materials, some of them have
anisotropic crystal structures; examples include different systems such as a few-layer black …

We elucidate the nature of neutral collective excitations of fractional quantum Hall liquids in
the long-wavelength limit. We demonstrate that they are chiral gravitons carrying angular …

In many-body systems with U (1) global symmetry, the charge fluctuations in a subregion
reveal important insights into entanglement and other global properties. For subregions with …

There has been a surge of recent interest in the role of anisotropy in interaction-induced
phenomena in two-dimensional (2D) charged carrier systems. A fundamental question is …

We investigate the nature of the quantum Hall liquid in a half-filled second Landau level (n=
1) as a function of band mass anisotropy using numerical exact diagonalization and density …

Composite fermions (CFs), exotic particles formed by pairing an even number of flux quanta
to each electron, provide a fascinating description of phenomena exhibited by interacting …

We present a detailed study of the ground-state entanglement in disordered fractional
quantum Hall liquids. We consider electrons at various filling fractions f in the lowest Landau …

We investigate the relation between the Fermi sea (FS) of zero-field carriers in two-
dimensional systems and the FS of the corresponding composite fermions which emerge in …

Two-dimensional interacting electrons exposed to strong perpendicular magnetic fields
generate emergent, exotic quasiparticles phenomenologically distinct from electrons …
