Non-Abelian Fibonacci quantum Hall states in 4-layer rhombohedral stacked graphene
Abigail Timmel, Xiao-Gang Wen
In 1991, it was proposed that fourfold-degenerate Landau levels formed by a single species of electrons could host a non-Abelian fractional quantum Hall (FQH) state with Fibonacci…
Condensation of fractional excitons, non-Abelian states in double-layer quantum Hall systems and Z_4 parafermions
Edward Rezayi, Xiao-Gang Wen, N. Read
In this paper, we study a method to obtain non-Abelian FQH state through double-layer FQH states and fractional exciton condensation. In particular, we find that starting with the…
Anyon Condensation and Continuous Topological Phase Transitions in Non-Abelian Fractional Quantum Hall States
Maissam Barkeshli, Xiao-Gang Wen
We find a series of possible continuous quantum phase transitions between fractional quantum Hall (FQH) states at the same filling fraction in two-component quantum Hall systems. T…
Non-Abelian Two-component Fractional Quantum Hall States
Maissam Barkeshli, Xiao-Gang Wen
A large class of fractional quantum Hall (FQH) states can be classified according to their pattern of zeros, which describes the order of zeros in ground state wave functions as va…
Classification of Abelian and Non-Abelian Multilayer Fractional Quantum Hall States Through the Pattern of Zeros
Maissam Barkeshli, Xiao-Gang Wen
A large class of fractional quantum Hall (FQH) states can be classified according to their pattern of zeros, which describes the way ideal ground state wave functions go to zero as…

Maissam Barkeshli, Xiao-Gang Wen
It was recently discovered that fractional quantum Hall (FQH) states can be classified by the way ground state wave functions go to zero when electrons are brought close together.…

Starting from the edge reconstructed Pfaffian state and the anti-Pfaffian state for the filling fraction fractional quantum Hall (FQH) state with the filled Landau levels…
Topological surface states in three-dimensional magnetic insulators
Joel E. Moore, Ying Ran, Xiao-Gang Wen
An electron moving in a magnetically ordered background feels an effective magnetic field that can be both stronger and more rapidly varying than typical externally applied fields.…

Xiao-Gang Wen, Zhenghan Wang
It has been shown that different Abelian and non-Abelian fraction quantum Hall states can be characterized by patterns of zeros described by sequences of integers {S_a}. In this pa…

Bas J. Overbosch, Xiao-Gang Wen
We calculate the non-linear I-V tunneling curves for a two-point-contact tunneling junction between two edges of the non-abelian fractional quantum Hall state. The non-li…
Artificial light and quantum order in systems of screened dipoles
Xiao-Gang Wen
The origin of light is a unsolved mystery in nature. Recently, it was suggested that light may originate from a new kind of order - quantum order. To test this idea in experiments,…
Critical points in edge tunneling between generic FQH states
Joel E. Moore, Xiao-Gang Wen
A general description of weak and strong tunneling fixed points is developed in the chiral-Luttinger-liquid model of quantum Hall edge states. Tunneling fixed points are a subset o…
Striped States in Quantum Hall Effect: Deriving a Low Energy Theory from Hartree-Fock
Anna Lopatnikova, Steven H. Simon, Bertrand I. Halperin +1
There is growing experimental and theoretical evidence that very clean two dimensional electron systems form unidirectional charge density waves (UCDW) or ``striped'' states at low…

The fate of integer quantum Hall effect (IQHE) at weak magnetic field is studied numerically in the presence of {\it correlated} disorders. We find a systematic {\it float-up} and…
