Method of spectral Green functions in driven open quantum dynamics
Alexander Karabanov, Walter Köckenberger
A novel method based on spectral Green functions is presented for the simulation of driven open quantum dynamics that can be described by the Lindblad master equation in Liouville…
Many-body kinetics of dynamic nuclear polarization by the cross effect
Alexander Karabanov, Daniel Wiśniewski, Federica Raimondi +2
Dynamic nuclear polarization (DNP) is an out-of-equilibrium method for generating non-thermal spin polarization which provides large signal enhancements in modern diagnostic method…
Phase transitions in electron spin resonance under continuous microwave driving
Alexander Karabanov, Dominic C. Rose, Walter Köckenberger +2
We study an ensemble of strongly coupled electrons under continuous microwave irradiation interacting with a dissipative environment, a problem of relevance to the creation of high…
Solid effect DNP polarization dynamics in a system of many spins
Daniel Wiśniewski, Alexander Karabanov, Igor Lesanovsky +1
We discuss the polarization dynamics during solid effect dynamic nuclear polarization (DNP) in a central spin model that consists of an electron surrounded by many nuclei. To this…
Dynamic nuclear polarization as kinetically constrained diffusion
Alexander Karabanov, Daniel Wisniewski, Igor Lesanovsky +1
Dynamic nuclear polarization (DNP) is a promising strategy for generating a significantly increased non-thermal spin polarization in nuclear magnetic resonance (NMR) applications t…
On the accuracy of the state space restriction approximation for spin dynamics simulations
Alexander Karabanov, Ilya Kuprov, Gareth Charnock +3
We present an algebraic foundation for the state space restriction approximation in spin dynamics simulations and derive applicability criteria as well as minimal basis set require…
