Dissipative Landau-Zener transition with decoherence rate
Le Tuan Anh Ho, Liviu Ungur, Liviu F. Chibotaru
An innovative microscopic model with a minimal number of parameters: tunneling splitting gap, external field sweeping velocity, and decoherence rate is used to describe dynamics of…
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…
Vibronic order and emergent magnetism in cubic double perovskites
Naoya Iwahara, Liviu F. Chibotaru
The synergistic interplay of different interactions in materials leads to the emergence of novel quantum phenomena. Spin-orbit and vibronic couplings usually counteract each other,…
