Imaging GHz surface acoustic wave modes in electrostricted LaAlO/SrTiO heterostructures
Ranjani Ramachandran, Sayanwita Biswas, Prithwijit Mandal +6
The LaAlO/SrTiO (LAO/STO) interface hosts a gate-tunable superconducting two-dimensional electron gas (2DEG) which can be programmed to create quantum devices such as balli…
Constructing a Quantum Twisting Microscope: Design Insights and Experimental Considerations
Sayanwita Biswas, Ranjani Ramachandran, Patrick Irvin +1
We report the details of construction and testing of a Quantum Twisting Microscope, a recently developed scanning probe instrument that enables twist angle dependent electronic mea…
KTaO3-Based Supercurrent Diode
Muqing Yu, Jieun Kim, Ahmed Omran +7
The supercurrent diode effect (SDE), characterized by nonreciprocal critical currents, represents a promising building block for future dissipationless electronics and quantum circ…
Engineered Chirality of One-Dimensional Nanowires
Megan Briggeman, Elliott Mansfield, Johannes Kombe +11
The origin and function of chirality in DNA, proteins, and other building blocks of life represent a central question in biology. Observations of spin polarization and magnetizatio…
Electric and Magnetic Field-dependent Tunneling between Coupled Nanowires
Shashank Anand, Ranjani Ramachandran, Kitae Eom +9
Coupled quasi-one-dimensional (quasi-1D) electron systems host rich emergent physics that cannot be accounted for by understanding isolated 1D electron systems alone. Open question…
Magnetically Tuned Metal-Insulator Transition in LaAlO/SrTiO Nanowire Arrays
Ranjani Ramachandran, Shashank Anand, Kitae Eom +9
A wide family of two dimensional (2D) systems, including stripe-phase superconductors, sliding Luttinger liquids, and anisotropic 2D materials, can be modeled by an array of couple…
