Electromagnetic Response of a Half-Filled Chern Band near Topological Criticality
Xinlei Yue, Fabian Pichler, Michael Knap +1
We evaluate electromagnetic-response observables in a half-filled Chern band, across a topological phase transition between a composite Fermi liquid (CFL) and a Fermi liquid (FL) p…
Topological phase transitions between bosonic and fermionic quantum Hall states near even-denominator filling factors
Evgenii Zheltonozhskii, Ady Stern, Netanel H. Lindner
We study the quantum critical point between the fermionic quantum Hall state and the bosonic quantum Hall state of Cooper pairs. Our study is motivated by the composite…
Flux attachment theory of fractional excitonic insulators
Steven Gassner, Ady Stern, C. L. Kane
The search for fractional quantized Hall phases in the absence of a magnetic field has primarily targeted flat-band systems that mimic the features of a Landau level. In an alterna…
Universal charge conductance at Abelian--non-Abelian quantum Hall interfaces
Misha Yutushui, Ady Stern, David F. Mross
Multiple topologically distinct quantum Hall phases can occur at the same Landau level filling factor. It is a major challenge to distinguish between these phases as they only diff…
Electronic Excitations in the Bulk of Fractional Quantum Hall States
Xinlei Yue, Ady Stern
We analyze electronic excitations (excitations generated by adding or removing one electron) in the bulk of fractional quantum Hall states in Jain sequence states, using composite…
Identifying the topological order of quantized half-filled Landau levels through their daughter states
Evgenii Zheltonozhskii, Ady Stern, Netanel H. Lindner
Fractional quantum Hall states at a half-filled Landau level are believed to carry an integer number of chiral Majorana edge modes, reflected in their thermal Hall co…
Compressible quantum liquid with vanishing Drude weight
Ahmed Abouelkomsan, Nisarga Paul, Ady Stern +1
We explore the possibility of quantum liquids that are compressible but have vanishing DC conductivity in the absence of disorder. We show that the composite Fermi liquid emerging…
Transport properties of a half-filled Chern band at the electron and composite fermion phases
Ady Stern, Liang Fu
We consider a half-filled Chern band and its transport properties in two phases that it may form, the electronic Fermi liquid and the composite-fermion Fermi liquid. For weak disor…
Spin orbit effects in a GaAs quantum dot in a parallel magnetic field
B. I. Halperin, Ady Stern, Y. Oreg +3
We analyze the effects of spin-orbit coupling on fluctuations of the conductance of a quantum dot fabricated in a GaAs heterostructure. We argue that spin-orbit effects may become…
The Evolution of Quasiparticle Charge in the Fractional Quantum Hall Regime
T. G. Griffiths, E. Comforti, M. Heiblum +2
The charge of quasiparticles in a fractional quantum Hall (FQH) liquid, tunneling through a partly reflecting constriction with transmission t, was determined via shot noise measur…
Half-filled Landau level as a Fermi liquid of dipolar quasiparticles
A. Stern, B. I. Halperin, F. von Oppen +1
In this paper we study the relation between the conventional Fermion-Chern-Simons (FCS) theory of the half-filled Landau level (nu=1/2), and alternate descriptions that are based o…
Singularities in the Fermi liquid description of a partially filled Landau level and the energy gaps of fractional quantum Hall states
Ady Stern, Bertrand I. Halperin
We consider a two dimensional electron system in an external magnetic field at and near an even denominator Landau level filling fraction. Using a fermionic Chern--Simons approach…
