Ultrafast electron dynamics in correlated systems probed by time-resolved photoemission spectroscopy
Tanusree Saha, Giovanni De Ninno
Doktorska disertacija
Oznake: complex systems;charge density wave;excitonic insulator;metastable phase;Mott insulator;non-equilibrium;spin density wave;timescales;dissertations;
Complex systems in condensed matter are characterized by strong coupling between different degrees of freedom constituting a solid. In materials described by many-body physics, these interactions may lead to the formation of new ground states such as excitonic insulators, Mott insulators, and ch ...

Oznake: ultrafast phenomena;time resolved photoemission;strongly correlated systems;transition metal dichalcogenide;
The two-dimensional transition-metal dichalcogenide 1T−TaS2 is a complex material standing out for its puzzling low temperature phase marked by signatures amenable to both Mott-insulating and charge-density wave states. Electronic Mott states, coupled to a lattice, respond to coherent optical excita ...

Orbital selective dynamics in Fe-pnictides triggered by polarized pump pulse excitations
G. Adhikary, Tanusree Saha, Primož Rebernik Ribič, Matija Stupar, Barbara Ressel, Jurij Urbančič, Giovanni De Ninno, A. Thamizhavel, Kalobaran Maiti

Quantum materials display exotic behaviours related to the interplay between temperature-driven phase transitions. Here, we study the electron dynamics in one such material, CaFe$_2$As$_2$, a parent Fe-based superconductor, employing time and angle-resolved photoemission spectroscopy. CaFe$_2$As$_2$ ...

Uncovering the nature of transient and metastable nonequilibrium phases in 1T − TaS[sub]2
Tanusree Saha, Arindam Pramanik, Barbara Ressel, A. Ciavardini, F. Frassetto, Federico Galdenzi, L. Poletto, Arun Ravindran, Primož Rebernik Ribič, Giovanni De Ninno

Oznake: angle resolved photoemission;time resolved photoemission;2D materials;charge density wave;Mott insulator;
Complex systems are characterized by strong coupling between different microscopic degrees of freedom. Photoexcitation of such materials can drive them into new transient and metastable hidden phases that may not have any counterparts in equilibrium. By exploiting femtosecond time- and angle-resolve ...
