Can Majorana zero modes in quantum Hall edges survive edge reconstruction?

Kishore Iyer, Amulya Ratnakar, Sumathi Rao +1

Parafermion zero modes can be trapped in the domain walls of quantum Hall edges proximitized by superconductors and ferromagnets. The fractional quantum Hall side strip ar…

Dynamic enhancement of conductance in fractional quantum Hall constriction

Sampurna Karmakar, Amulya Ratnakar, Sourin Das

A disparity in the charge of quasi-particle excitations across a tunnel junction can trigger Andreev-like processes, creating an effect similar to that of a step-up transformer. We…

Quantum spin Hall insulator in proximity with a superconductor: Transition to the Fulde-Ferrell-Larkin-Ovchinnikov state driven by a Zeeman field

Suman Jyoti De, Udit Khanna, Sumathi Rao +1

We investigate the effects of introducing a boost (a Zeeman field parallel to the spin quantization axis) at the proximitized helical edge of a two-dimensional (2D) quantum spin Ha…

Observing super-quantum correlations across the exceptional point in a single, two-level trapped ion

Alexander Quinn, Jeremy Metzner, Jacob E. Muldoon +5

Quantum theory provides rules governing much of the microscopic world, and among its counter-intuitive consequences are correlations that exceed the bounds from local, classical th…

Multipartite entanglement and quantum error identification in -dimensional cluster states

Sowrabh Sudevan, Daniel Azses, Emanuele G. Dalla Torre +2

An entangled state is said to be -uniform if the reduced density matrix of any qubits is maximally mixed. This is intimately linked to pure quantum error correction codes (Q…

Volkov-Pankratov states on the edge of a quantum spin Hall system

Vivekananda Adak, Subhadeep Chakraborty, Krishanu Roychowdhury +1

Volkov-Pankratov (VP) states are a family of sub-gap states which appear at the smooth interface/domain wall between topologically distinct gapped states. We study the emergence of…
