Non-Markovian dynamics of mixed-state geometric phase of dissipative qubits
Wei Guo, Jian Ma, Xiaolei Yin +2
We investigate the geometric phase of a two-level atom (qubit) coupled to a bosonic reservoir with Lorentzian spectral density, and find that for the non-Markovian dynamics in whic…
Visualization of the normal-fluid turbulence in counterflowing superfluid 4He
Alex Marakov, Jian Gao, Wei Guo +4
We describe a new technique, using thin lines of triplet-state He2 molecular tracers created by femtosecond-laser field-ionization of helium atoms, for visualizing the flow of the…
Spin-transfer torque induced spin waves in antiferromagnetic insulators
Matthew W. Daniels, Wei Guo, G. Malcolm Stocks +2
We explore the possibility of exciting spin waves in insulating antiferromagnetic films by injecting spin current at the surface. We analyze both magnetically compensated and uncom…
Intrinsic magnetoresistance in metal films on ferromagnetic insulators
Vahram L. Grigoryan, Wei Guo, Gerrit E. W. Bauer +1
We predict a magnetoresistance induced by the interfacial Rashba spin-orbit coupling in normal metal|ferromagnetic insulator bilayer. It depends on the angle between current and ma…
Superlinear density dependence of singlet fission rate in tetracene films
Bo Zhang, Chunfeng Zhang, Rui Wang +6
We experimentally show that the rate of singlet fission in tetracene films has a superlinear dependence on the density of photo-excited singlet excitons with ultrafast transient ab…
