Optomechanical microwave amplification without mechanical amplification
Martijn A. Cohen, Daniel Bothner, Yaroslav M. Blanter +1
High-gain and low-noise signal amplification is a valuable tool in various cryogenic microwave experiments. A microwave optomechanical device, in which a vibrating capacitor modula…
Investigating laser induced phase engineering in MoS2 transistors
Nikos Papadopoulos, Joshua O. Island, Herre S. J. van der Zant +1
Phase engineering of MoS2 transistors has recently been demonstrated and has led to record low contact resistances. The phase patterning of MoS2 flakes with laser radiation has als…
Interaction-driven giant orbital magnetic moments in carbon nanotubes
Joshua O. Island, Marvin Ostermann, Lee Aspitarte +5
Carbon nanotubes continue to be model systems for studies of confinement and interactions. This is particularly true in the case of so-called "ultra-clean" carbon nanotube devices…
Bimodal Phase Diagram of the Superfluid Density in LaAlO3/SrTiO3 Revealed by an Interfacial Waveguide Resonator
Nicola Manca, Daniel Bothner, Ana M. R. V. L. Monteiro +6
We explore the superconducting phase diagram of the two-dimensional electron system at the LaAlO3/SrTiO3 interface by monitoring the frequencies of the cavity modes of a coplanar w…
A ballistic graphene superconducting microwave circuit
Felix E. Schmidt, Mark D. Jenkins, Kenji Watanabe +2
Josephson junctions (JJ) are a fundamental component of microwave quantum circuits, such as tunable cavities, qubits and parametric amplifiers. Recently developed encapsulated grap…
Tuneable hopping and nonlinear cross-Kerr interactions in a high-coherence superconducting circuit
M. Kounalakis, C. Dickel, A. Bruno +2
Analog quantum simulations offer rich opportunities for exploring complex quantum systems and phenomena through the use of specially engineered, well-controlled quantum systems. A…
