Floquet Engineering of Quantum Transport through two Driven Impurities
Vincenzo Bruno, Corinna Kollath, Roberta Citro +1
Floquet engineering offers powerful tools to manipulate quantum states by periodically driving physical parameters. In this work, we investigate the quantum transport through two p…
Inhomogeneous superconductivity in (001), (110), and (111) KTaO two-dimensional electronic gases: effect of electronic confinement on the transition temperature
Mattia Trama, Matta Trama, Roberta Citro +1
Experimental observations on KTaO superconductivity report widely different critical temperatures with a clear hierarchy among different crystallographic orientations. Accounti…
Intrinsic Negative-U Centers in Freestanding LaAlO3/SrTiO3 Micro-membranes
Giulia Meucci, Pinelopi O. Konstantinopoulou, Thies Jansen +15
The LaAlO3/SrTiO3 (LAO/STO) interface hosts a rich range of electronic phenomena, including unconventional electron pairing that in quantum dots gives rise to a negative effective…
Scanning gate microscopy probing of anisotropic electron flow in a two dimensional electron gas at the (110) interface: A theoretical investigation
M. P. Nowak, M. Zegrodnik, D. Grzelec +3
We theoretically investigate the anisotropic dispersion features of a two dimensional electron gas at the (110) oriented interfaces, as revealed…
Photoengineering the Magnon Spectrum in an Insulating Antiferromagnet
V. Radovskaia, R. Andrei, J. R. Hortensius +9
Femtosecond optical pulses have opened a new frontier in ultrafast dynamics, enabling direct access to fundamental interactions in quantum materials. In antiferromagnets (AFMs), wh…
Scaled tight binding model for a two dimensional electron gas at the (001) LaAlO/SrTiO interface
P. Wójcik, R. Citro, B. Szafran
The progress in the fabrication of nanoscale systems based on the two-dimensional electron gas at the interface between LaAlO and SrTiO (LAO/STO) has created an increased d…
