On the Detection of Curl-Free Gauge Fields
Armen Gulian, Will Benston, Vahan Nikoghosyan
In quantum theory, electromagnetic gauge fields enter directly into the phase evolution of the wavefunction and can even influence quantum systems in regions where the associated e…
Revisiting apparent ideal diamagnetism at ambient conditions in graphene-n-heptane-permalloy systems
Rajendra Dulal, Serafim Teknowijoyo, Sara Chahid +2
We previously reported apparent ideal diamagnetism at ambient conditions in a graphene-n-heptane-permalloy system. At the same time, the experiments revealed inconsistent behavior,…
Glassy magnetic freezing of interacting clusters in LK-99-family materials
Serafim Teknowijoyo, Domenico Napoletani, Vahan Nikoghosyan +1
We report reproducible magnetization anomalies appearing below room temperature in copper-doped apatite materials belonging to the LK-99 family synthesized via hydrothermal methods…
Diode Effect May Assist Finding Proper Superconductivity Mechanism in Copper Oxides
Armen Gulian, Serafim Teknowijoyo, Vahan Nikoghosyan
We present measurements demonstrating that copper-oxide high-temperature superconductors can exhibit broken time-reversal symmetry in the absence of external magnetic fields. Using…
Anisotropic second-harmonic generation in superconducting nanostructures
Sara Memarzadeh, Maciej Krawczyk, Armen Gulian +1
Circuits based on superconducting nanostructures are among the most promising platforms for quantum computing. Understanding how device geometry governs nonlinear electrodynamics i…
Gate-controlled supercurrent effect in dry-etched Dayem bridges of non-centrosymmetric niobium rhenium
Jennifer Koch, Carla Cirillo, Sebastiano Battisti +10
The application of a gate voltage to control the superconducting current flowing through a nanoscale superconducting constriction, named as gate-controlled supercurrent (GCS), has…
Demonstration of high-impedance superconducting NbRe Dayem bridges
S. Battisti, J. Koch, A. Paghi +10
Here we demonstrate superconducting Dayem-bridge weak-links made of different stoichiometric compositions of NbRe. Our devices possess a relatively high critical temperature, norma…
Extraordinary physical properties of superconducting YBaSrCuOSe in a multiphase ceramic material
V. Grinenko, A. Dudka, S. Nozaki +10
We report on a novel material obtained by modifying pristine YBCO superconductor in solid phase synthesis via simultaneous partial substitution of Ba by Sr and O by Se. Simultaneou…
Novel results obtained by modeling of dynamic processes in superconductors: phase-slip centers as cooling engines
Iris Mowgood, Serafim Teknowijoyo, Sara Chahid +1
Based on a time-dependent Ginzburg-Landau system of equations and finite element modeling, we present novel results related with the physics of phase-slippage in superconducting wi…
