Multipartite entanglement in two-dimensional chiral topological liquids
Yuhan Liu, Yuya Kusuki, Jonah Kudler-Flam +2
The multipartite entanglement structure for the ground states of two dimensional topological phases is an interesting albeit not well understood question. Utilizing the bulk-bounda…
Entanglement in tripartitions of topological orders: a diagrammatic approach
Ramanjit Sohal, Shinsei Ryu
Recent studies have demonstrated that measures of tripartite entanglement can probe data characterizing topologically ordered phases to which bipartite entanglement is insensitive.…
Theory of oblique topological insulators
Benjamin Moy, Hart Goldman, Ramanjit Sohal +1
A long-standing problem in the study of topological phases of matter has been to understand the types of fractional topological insulator (FTI) phases possible in 3+1 dimensions. U…
Multipartitioning topological phases by vertex states and quantum entanglement
Yuhan Liu, Ramanjit Sohal, Jonah Kudler-Flam +1
We discuss multipartitions of the gapped ground states of (2+1)-dimensional topological liquids into three (or more) spatial regions that are adjacent to each other and meet at poi…
Thermalization of Randomly Coupled SYK Models
Ramanjit Sohal, Laimei Nie, Xiao-Qi Sun +1
We investigate the thermalization of Sachdev-Ye-Kitaev (SYK) models coupled via random interactions following quenches from the perspective of entanglement. Previous studies have s…
A composite particle construction of the Fibonacci fractional quantum Hall state
Hart Goldman, Ramanjit Sohal, Eduardo Fradkin
The Fibonacci topological order is the simplest platform for a universal topological quantum computer, consisting of a single type of non-Abelian anyon, , with fusion rule $τ\ti…
Non-Abelian Fermionization and the Landscape of Quantum Hall Phases
Hart Goldman, Ramanjit Sohal, Eduardo Fradkin
The recent proposal of non-Abelian boson-fermion dualities in 2+1 dimensions, which morally relate to Chern-Simons-matter theories, presents a new platform fo…
Entanglement Entropy of Generalized Moore-Read Fractional Quantum Hall State Interfaces
Ramanjit Sohal, Bo Han, Luiz H. Santos +1
Topologically ordered phases of matter can be characterized by the presence of a universal, constant contribution to the entanglement entropy known as the topological entanglement…
Intertwined Order in Fractional Chern Insulators from Finite-Momentum Pairing of Composite Fermions
Ramanjit Sohal, Eduardo Fradkin
We investigate the problem of intertwined orders in fractional Chern insulators by considering lattice fractional quantum Hall (FQH) states arising from pairing of composite fermio…
Landau-Ginzburg Theories of Non-Abelian Quantum Hall States from Non-Abelian Bosonization
Hart Goldman, Ramanjit Sohal, Eduardo Fradkin
It is an important open problem to understand the landscape of non-Abelian fractional quantum Hall phases which can be obtained starting from physically motivated theories of Abeli…
Chern-Simons Composite Fermion Theory of Fractional Chern Insulators
Ramanjit Sohal, Luiz H. Santos, Eduardo Fradkin
We formulate a Chern-Simons composite fermion theory for Fractional Chern Insulators (FCIs), whereby bare fermions are mapped into composite fermions coupled to a lattice Chern-Sim…
