Negative charging energy in LaAlO/SrTiO quantum dots induced by SrTiO polarization
J. Czarnecki, A. Sierant, B. Szafran +12
We propose a microscopic mechanism for the negative charging energy in LaAlO/SrTiO quantum dots, arising from the electrostatic image charge associated with the paraelectri…
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…

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…

Jinfeng Zhai, Mattia Trama, Hao Liu +6
The two-dimensional electron gas (2DEG) at oxide interfaces exhibits various exotic properties stemming from interfacial inversion symmetry breaking. In this work, we report the em…
Electric dipole spin resonance in single and two electron quantum dot defined in two-dimensional electron gas at the SrTiO/LaAlO interface
B. Szafran, M. Zegrodnik. M. P. Nowak, R. Citro +1
We investigate the energy spectrum of a single and two electron quantum dot (QD) embedded in two dimensional electron gas at the interface between SrTiO and LaAlO, in the p…
Interplay between charge-lattice interaction and strong electron correlations in cuprates: phonon anomaly and spectral kinks
G. De Filippis, V. Cataudella, R. Citro +3
We investigate the interplay between strong electron correlations and charge-lattice interaction in cuprates. The coupling between half breathing bond stretching phonons and doped…
