Initial Design of a W-band Superconducting Kinetic Inductance Qubit (Kineticon)

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Farzad B. Faramarzi, Peter K. Day, Jacob Glasby, Sasha Sypkens, Marco Colangelo | Summary: Superconducting qubits are widely used in quantum computing research and industry. We describe a superconducting kinetic inductance qubit (and introduce the term Kineticon to describe it) operating at W-band frequencies with a nonlinear […]

Bloch-Lorentz magnetoresistance oscillations in delafossites

Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations closely resembling the Aharonov-Bohm effect. Here, we show that the magnetoresistance oscillations are explained by the Bloch-like oscillations of the out-of-plane electron trajectories. We develop […]

Bloch-Lorentz magnetoresistance oscillations in delafossites

Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations which closely resemble the Aharanov-Bohm effect. We develop a semiclassical theory of these oscillations and show that they are a consequence of the quasi-2D dispersion […]

Gravitational wave constraints on the primordial black hole dominated early universe

Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Chunshan Lin, Misao Sasaki, , | Summary: We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually dominate and reheat the universe by Hawking evaporation. The initial PBH density […]
