Multi-Band Petahertz Currents Resolved via High Harmonic Generation Spectroscopy
Ayelet Julie Uzan, Gal Orenstein, Álvaro Jiménez-Galán +13
Strong field driven electric currents in condensed matter systems open new frontiers in petahertz electronics. In this regime new challenges arise as the role of the band structure…
Information Loss Pathways in a Numerically Exact Simulation of a non-Markovian Open Quantum System
Evgeny A. Polyakov, Alexey N. Rubtsov
In the non-Markovian regime, the bath has the memory about the past behavior of the open quantum system. This memory has slowly-decaying power-law tails. Such a long-range characte…
Dressed Quantum Trajectories: Novel Approach to the non-Markovian Dynamics of Open Quantum Systems on a Wide Time Scale
Evgeny A. Polyakov, Alexey N. Rubtsov
A new approach to the theory and simulation of the non-Markovian dynamics of open quantum systems is presented. It is based on identification of a parameter which is uniformly smal…
Fluctuations and photon statistics in quantum metamaterial near the superradiant transition
D. S. Shapiro, A. N. Rubtsov, S. V. Remizov +2
The analysis of single-mode photon fluctuations and their counting statistics at the superradiant phase transition is presented. The study concerns the equilibrium Dicke model in a…
Spin transfer torque induced paramagnetic resonance
Alexey M. Shakirov, Alexey N. Rubtsov, Pedro Ribeiro
We show how the spin-transfer torque generated by an ac voltage may be used to excite a paramagnetic resonance of an atomic spin deposited on a metallic surface. This mechanism is…
Quantum spin fluctuations and evolution of electronic structure in cuprates
E. A. Stepanov, L. Peters, I. S. Krivenko +3
Correlation effects in CuO layers give rise to a complicated landscape of collective excitations in high-T cuprates. Their description requires an accurate account fo…
