Frustrated edge currents in bilayers formed of s- and d-wave superconductors
Vedangi Pathak, Oguzhan Can, Nirek Brahmbhatt +1
We explore edge currents in heterostructures formed of a high- cuprate and a conventional -wave superconductors. The resulting superconductor spontaneously breaks…
NMon: enhanced transmon qubit based on parallel arrays of Josephson junctions
Oguzhan Can, Marcel Franz
We introduce a novel superconducting qubit architecture utilizing parallel arrays of Josephson junctions. This design offers a substantialy improved relative anharmonicity, typical…
Edge currents as probe of topology in twisted cuprate bilayers
Vedangi Pathak, Oguzhan Can, Marcel Franz
Bilayers made of high- cuprate superconductor BiSrCaCuO assembled with a twist angle close to have been recently shown to spontaneously break ti…
-mon: transmon with strong anharmonicity
Hrishikesh Patel, Vedangi Pathak, Oguzhan Can +2
We propose a novel qubit architecture based on a planar -axis Josephson junction between a thin flake -wave superconductor (SC), such as a high- cuprate BiSrC…
Superconducting diode from flux biased Josephson junction arrays
Rafael Haenel, Oguzhan Can
We propose a realization of the superconducting diode effect in flux biased superconducting circuits of Josephson junctions. So far the observation of the superconducting diode eff…
Probing time reversal symmetry breaking topological superconductivity in twisted double layer copper oxides with polar Kerr effect
Oguzhan Can, Xiao-Xiao Zhang, Catherine Kallin +1
Recent theoretical work predicted emergence of chiral topological superconducting phase with spontaneously broken time reversal symmetry in a twisted bilayer composed of two high-$…
Chiral -wave superconductivity in a twisted array of proximitized quantum wires
Tarun Tummuru, Oguzhan Can, Marcel Franz
A superconductor with order has long fascinated the physics community because vortex defects in such a system host Majorana zero modes. Here we propose a simple construc…
High-temperature topological superconductivity in twisted double layer copper oxides
Oguzhan Can, Tarun Tummuru, Ryan P. Day +3
A great variety of novel phenomena occur when two-dimensional materials, such as graphene or transition metal dichalcogenides, are assembled into bilayers with a twist between indi…
Diagnosing quantum chaos in many-body systems using entanglement as a resource
Étienne Lantagne-Hurtubise, Stephan Plugge, Oguzhan Can +1
Classical chaotic systems exhibit exponentially diverging trajectories due to small differences in their initial state. The analogous diagnostic in quantum many-body systems is an…
Solvable model for quantum criticality between Sachdev-Ye-Kitaev liquid and disordered Fermi liquid
Oguzhan Can, Marcel Franz
We propose a simple solvable variant of the Sachdev-Ye-Kitaev (SYK) model which displays a quantum phase transition from a fast-scrambling non-Fermi liquid to disordered Fermi liqu…
Charge transport in graphene-based mesoscopic realizations of Sachdev-Ye-Kitaev models
Oguzhan Can, Emilian M. Nica, Marcel Franz
We consider a recent proposal for a physical realization of the Sachdev-Ye-Kitaev (SYK) model in the zeroth-Landau-level sector of an irregularly-shaped graphene flake. We study in…
Topological edge states in single layers of honeycomb materials with strong spin-orbit coupling
Andrei Catuneanu, Heung-Sik Kim, Oguzhan Can +1
We study possible edge states in single layers of honeycomb materials such as -RuCl and AIrO (A=Li, Na) with strong spin-orbit coupling (SOC). These two dimensional…
