Massive Higher-Spin Fields in the Fractional Quantum Hall Effect
Eric Bergshoeff, Andrea Campoleoni, Giandomenico Palumbo +1
Incompressibility plays a key role in the geometric description of fractional quantum Hall fluids. It is naturally related to quantum area-preserving diffeomorphisms and the underl…
Interacting second-order topological insulators in one-dimensional fermions with correlated hopping
A. Montorsi, U. Bhattacharya, Daniel González-Cuadra +3
Higher-order topological crystalline phases in low-dimensional interacting quantum systems represent a challenging and largely unexplored research topic. Here, we derive a Hamilton…
Specific heat of 2D interacting Majorana fermions from holography
Paolo Maraner, Jiannis K. Pachos, Giandomenico Palumbo
Majorana fermions are a fascinating medium for discovering new phases of matter. However, the standard analytical tools are very limited in probing the non-perturbative aspects of…
Chern-Simons theory and atypical Hall conductivity in the Varma phase
N. Menezes, C. Morais Smith, Giandomenico Palumbo
In this letter, we analyze the topological response of a fermionic model defined on the Lieb lattice in presence of an electromagnetic field. The tight-binding model is built in te…
Excitonic gap generation in thin-film topological insulators
N. Menezes, C. Morais Smith, Giandomenico Palumbo
In this work, we analyze the excitonic gap generation in the strong-coupling regime of thin films of three-dimensional time-reversal-invariant topological insulators. We start by w…
Skyrmion Superfluidity in Two-Dimensional Interacting Fermionic Systems
Giandomenico Palumbo, Mauro Cirio
In this article we describe a multi-layered honeycomb lattice model of interacting fermions which supports a new kind of parity-preserving skyrmion superfluidity. We derive the low…
Non-Abelian Chern-Simons Theory from a Hubbard-like Model
Giandomenico Palumbo, Jiannis K. Pachos
Here, we provide a simple Hubbard-like model of spin- fermions that gives rise to the SU(2) symmetric Thirring model that is equivalent, in the low-energy limit, to Yang-Mills…
(3+1)-dimensional topological quantum field theory from a tight-binding model of interacting spinless fermions
Mauro Cirio, Giandomenico Palumbo, Jiannis K. Pachos
Currently, there is much interest in discovering analytically tractable (3+1)-dimensional models that describe interacting fermions with emerging topological properties. Towards th…
Abelian Chern-Simons-Maxwell theory from a tight binding model of spinless fermions
Giandomenico Palumbo, Jiannis K. Pachos
Abelian Chern-Simons-Maxwell theory can emerge from the bosonisation of the 2+1-dimensional Thirring model that describes interacting Dirac fermions. Here we show how the Thirring…
