Vanishing thermal equilibration for hole-conjugate fractional quantum Hall states in graphene
Saurabh Kumar Srivastav, Ravi Kumar, Christian Spånslätt +5
Transport through edge-channels is responsible for conduction in quantum Hall (QH) phases. Topology dictates quantization of both charge and thermal transport coefficients. These t…
Emergence of spin-active channels at a quantum Hall interface
Amartya Saha, Suman Jyoti De, Sumathi Rao +2
We study the ground state of a system with an interface between and in the quantum Hall regime. Far from the interface, for a range of interaction strengths, the …
Fractional Edge Reconstruction in Integer Quantum Hall Phases
Udit Khanna, Moshe Goldstein, Yuval Gefen
Protected edge modes are the cornerstone of topological states of matter. The simplest example is provided by the integer quantum Hall state at Landau level filling unity, which sh…
Noise on the Non-Abelian Fractional Quantum Hall Edge
Jinhong Park, Christian Spånslätt, Yuval Gefen +1
The recent measurement of a half-integer thermal conductance for the fractional quantum Hall state has confirmed its non-Abelian nature, making the question of the underlyi…
Weak-measurement-induced phases and dephasing: broken symmetry of the geometric phase
Kyrylo Snizhko, Nihal Rao, Parveen Kumar +1
Coherent steering of a quantum state, induced by a sequence of weak measurements, has become an active area of theoretical and experimental study. For a closed steered trajectory,…
Weak-measurement-induced asymmetric dephasing: manifestation of intrinsic measurement chirality
Kyrylo Snizhko, Parveen Kumar, Nihal Rao +1
Geometrical dephasing is distinct from dynamical dephasing in that it depends on the trajectory traversed, hence it reverses its sign upon flipping the direction in which the path…
