Enigmatic 2+6/13 Filling Factor: A Prototype Intermittent Topological State

Autor: Das, Sudipto, Das, Sahana, Mandal, Sudhansu S.

Observation of filling factor 6/13 is one of the surprising fractional quantum Hall states in the second Landau level because, in contrast to the standard wisdom, the fractions ($\nu < 1/2$) with lower numerators, namely 4 and 5, have not yet been ob

Reply to 'Comment on `Anomalous Reentrant 5/2 Quantum Hall Phase at Moderate Landau-Level-Mixing Strength' '

The proposed $\mathcal{A}$ phase and the corresponding trial wavefunction proposed by Das \emph{et al.} (PRL 131, 056202, 2023) for 5/2 state are argued to describe the fractional quantum Hall liquid state rather than a phase separated or stripe or b

A proposal of the existence of an {\em Anomalous} phase ($\mathcal{A}$ phase) [https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.131.056202 Das et al., Phys. Rev. Lett. 131, 056202 (2023)] at the experimental range of moderate Landau-level-mi

An Anomalous Reentrant 5/2 Quantum Hall Phase at Moderate Landau-Level-Mixing Strength

Publikováno v: Phys. Rev. Lett. 131, 056202 (2023)

A successful probing of neutral Majorana mode in recent thermal Hall conductivity measurements opines in favor of the particle-hole symmetric Pfaffian (PH-Pf) topological order, contrasting the theoretical predictions of Pfaffian or anti-Pfaffian pha

From the Gaffnian critical point to the incompressible 2/5 quantum Hall state

Autor: Das, Sahana, Das, Sudipto, Mukherjee, Sutirtha, Mandal, Sudhansu S.

Despite the high overlap with the exact Coulomb ground state, the so-called Gaffnian state fails to describe the incompressibility at the 2/5 quantum Hall filling factor and consequently it was conjectured to be a quantum critical state. To achieve a

Unconventional Filling Factor 4/11: A Closed-Form Ground State Wave Function

Autor: Das, Sahana, Das, Sudipto, Mandal, Sudhansu S.

Publikováno v: Phys. Rev. B 103, 075304 (2021)

The ground state at 4/11 filling factor is very well understood [Phys. Rev. Lett. 112, 016801 (2014)] in terms of the 1/3 filled second effective Landau level of the composite fermions whose correlations resemble with that of electrons in the ground
