Observation of a Zero-Field Josephson Diode Effect in a Helimagnet Josephson Junction
Alexander Beach, Mostafa Tanhayi Ahari, Younghyuk Kim +4
We present Josephson junctions with the metallic chiral helimagnet CrNbS as the weak link that exhibit magnetic diffraction patterns with asymmetry in both applied ma…
Superconducting magnetoelectric effects in mesoscopic hybrid structures
Mostafa Tanhayi Ahari, Yaroslav Tserkovnyak
In superconductors that lack inversion symmetry, a supercurrent flow can lead to nondissipative magnetoelectric effects. We offer a straightforward formalism to obtain a supercurre…
Long-range Phase Coherence and Tunable Second Order -Josephson Effect in a Dirac Semimetal
Pranava K. Sivakumar, Mostafa T. Ahari, Jae-Keun Kim +6
Superconducting diode effects have recently attracted much attention for their potential applications in superconducting logic circuits. Several mechanisms such as magneto-chiral e…
Magnetic-field-free nonreciprocal transport in graphene multi-terminal Josephson junctions
Fan Zhang, Asmaul Smitha Rashid, Mostafa Tanhayi Ahari +6
Nonreciprocal superconducting devices have attracted growing interest in recent years as they potentially enable directional charge transport for applications in superconducting qu…
Andreev processes in mesoscopic multi-terminal graphene Josephson junctions
Fan Zhang, Asmaul Smitha Rashid, Mostafa Tanhayi Ahari +7
There is growing interest in using multi-terminal Josephson junctions (MTJJs) as a platform to artificially emulate topological phases and to investigate complex superconducting me…
Partons as unique ground states of quantum Hall parent Hamiltonians: The case of Fibonacci anyons
M. Tanhayi Ahari, S. Bandyopadhyay, Z. Nussinov +2
We present microscopic, multiple Landau level, (frustration-free and positive semi-definite) parent Hamiltonians whose ground states, realizing different quantum Hall fluids, are p…
Superconductivity-enhanced spin pumping: Role of Andreev resonances
Mostafa Tanhayi Ahari, Yaroslav Tserkovnyak
We describe a simple hybrid superconductorferromagnetic-insulator structure manifesting spin-resolved Andreev bound states in which dynamic magnetization is employed to probe sp…
Entangled Pauli Principles: the DNA of Quantum Hall Fluids
Sumanta Bandyopadhyay, Li Chen, Mostafa Tanhayi Ahari +3
A formalism is developed for the rigorous study of solvable fractional quantum Hall parent Hamiltonians with Landau level mixing. The idea of organization through "generalized Paul…
Non-Abelian fermion parity interferometry of Majorana bound states in a Fermi sea
Daniel Dahan, Mostafa Tanhayi Ahari, Gerardo Ortiz +2
We study the quantum dynamics of Majorana and regular fermion bound states coupled to a quasi-one-dimensional metallic lead. The dynamics following the quench in the coupling to th…
On the Role of Self-Adjointness in the Continuum Formulation of Topological Quantum Phases
Mostafa Tanhayi Ahari, Gerardo Ortiz, Babak Seradjeh
Topological quantum phases of matter are characterized by an intimate relationship between the Hamiltonian dynamics away from the edges and the appearance of bound states localized…
