Three-dimensional Foliated Fractional Quantum Hall Phases

Sahana Das, Navketan Batra, Andrea Kouta Dagnino +4

Foliated topological orders in three dimensions are layered systems in which anyons are free to move within a layer but cannot hop between them. A simple model with such a phase is…

Fractional topological insulators at odd-integer filling: Phase diagram of two-valley quantum Hall model

Sahana Das, Glenn Wagner, Titus Neupert

The fractional quantum Hall effect has recently been shown to exist in heterostructures of van der Waals materials without an externally applied magnetic field, e.g. in twisted bil…

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

Sudipto Das, Sahana Das, Sudhansu S. Mandal

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 ($ν…

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

Sudipto Das, Sahana Das, Sudhansu S. Mandal

The proposed 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…

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

Sudipto Das, Sahana Das, Sudhansu S. Mandal

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, co…

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

Sahana Das, Sudipto Das, Sutirtha Mukherjee +1

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 conseq…

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

Sahana Das, Sudipto Das, Sudhansu S. Mandal

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 ferm…
