Modeling of Transient Absorption Spectra in Exciton Charge-Transfer Systems
Tobias Kramer, Mirta Rodriguez, Yaroslav Zelinskyy
Time-resolved spectroscopy provides the main tool for analyzing the dynamics of excitonic energy transfer in light-harvesting complexes. To infer time-scales and effective coupling…
Efficient calculation of open quantum system dynamics and time-resolved spectroscopy with Distributed Memory HEOM (DM-HEOM)
Tobias Kramer, Matthias Noack, Alexander Reinefeld +2
Time- and frequency resolved optical signals provide insights into the properties of light harvesting molecular complexes, including excitation energies, dipole strengths and orien…
Two-dimensional electronic spectra of the photosynthetic apparatus of green sulfur bacteria
Tobias Kramer, Mirta Rodriguez
Advances in time resolved spectroscopy have provided new insight into the energy transmission in natural photosynthetic complexes. Novel theoretical tools and models are being deve…
High-performance solution of hierarchical equations of motions for studying energy-transfer in light-harvesting complexes
Christoph Kreisbeck, Tobias Kramer, Mirta Rodriguez +1
Excitonic models of light-harvesting complexes, where the vibrational degrees of freedom are treated as a bath, are commonly used to describe the motion of the electronic excitatio…
Fermion- and spin-counting in strongly correlated systems in and out of thermal equilibrium
Sibylle Braungardt, Mirta Rodriguez, Aditi Sen De +3
Atom counting theory can be used to study the role of thermal noise in quantum phase transitions and to monitor the dynamics of a quantum system. We illustrate this for a strongly…
Quantum polarization spectroscopy of correlations in attractive fermionic gases
T. Roscilde, M. Rodriguez, K. Eckert +4
We show how spin-spin correlations, detected in a non-destructive way via spatially resolved quantum polarization spectroscopy, strongly characterize various phases realized in tra…
Quantum Non-Demolition Detection of Strongly Correlated Systems
Kai Eckert, Oriol Romero-Isart, Mirta Rodriguez +3
Preparation, manipulation, and detection of strongly correlated states of quantum many body systems are among the most important goals and challenges of modern physics. Ultracold a…
Quantum theory of an atom laser originating from a Bose-Einstein condensate or a Fermi gas in the presence of gravity
Tobias Kramer, Mirta Rodriguez
We present a 3D quantum mechanical theory of radio-frequency outcoupled atom lasers from trapped atomic gases in the presence of the gravitational force. Predictions for the total…
Pairing gap and in-gap excitations in trapped fermionic superfluids
J. Kinnunen, M. Rodriguez, P. Torma
We consider trapped atomic Fermi gases with Feshbach-resonance enhanced interactions in pseudogap and superfluid temperatures. We calculate the spectrum of RF(or laser)-excitations…
Laser probing of Cooper-paired trapped atoms
G. M. Bruun, P. Torma, M. Rodriguez +1
We consider a gas of trapped Cooper-paired fermionic atoms which are manipulated by laser light. The laser induces a transition from an internal state with large negative scatterin…
Tailoring of vibrational state populations with light-induced potentials in molecules
M. Rodriguez, K. -A. Suominen, B. M. Garraway
We propose a method for achieving highly efficient transfer between the vibrational states in a diatomic molecule. The process is mediated by strong laser pulses and can be underst…
