New tool for extraction of Os Mössbauer parameters with biologically relevant detection sensitivity
Iryna Stepanenko, Zhishuo Huang, Liviu Ungur +8
A large number of osmium complexes with osmium in different oxidation states (II, III, IV, VI) have been reported recently to exhibit good antiproliferative activity in cancer cell…
Coherence/incoherence transition temperature in molecular spin
Le Tuan Anh Ho, Liviu Ungur, Liviu F. Chibotaru
We examine the coherence/incoherence transition temperature of a generic molecular spin. Our results demonstrates that a molecular spin with a high coherence/incoherence transition…
Quantum tunneling of magnetization in molecular spin
Le Tuan Anh Ho, Liviu Ungur, Liviu F. Chibotaru
We examine the quantum tunneling of magnetization in molecular spin in weak interaction with a bath subject to Redfield master equation. By designing a microscopic model for a mult…
Non-monotonic temperature dependence and first-order phase transition of relaxation times in molecular spin
Le Tuan Anh Ho, Liviu Ungur, Liviu F. Chibotaru
We derive a simple system of equations to describe the magnetization relaxation of a molecular spin in weak interaction with a thermal bath for the whole temperature domain. Using…
Unique determination of localized basis in molecular spin
Le Tuan Anh Ho, Liviu Ungur
Localized basis plays an important role in comprehending the magnetic dynamics in molecular spins from a physics perspective. Nonetheless, the uniqueness and rigor of its determina…
