Magnetic Impurities in Graphene
F. M. Hu, Tianxing Ma, Hai-Qing Lin +1
We used a quantum Monte Carlo method to study the magnetic impurity adatoms on graphene. We found that by tuning the chemical potential we could switch the values of the impurity's…
Convex-transitivity of Banach algebras via ideals
Jarno Talponen
We investigate a method for producing concrete convex-transitive Banach spaces. The gist of the method is in getting rid of dissymmetries of a given space by taking a carefully cho…
Generalized partial measurements
G. S. Paraoanu
We introduce a type of measurements that generalize the so-called "partial measurements" performed in recent years with phase qubits. While in the case of partial measurements it h…
Impact of lithium composition on the thermoelectric properties of the layered cobalt oxide system LixCoO2
T. Motohashi, Y. Sugimoto, Y. Masubuchi +5
Thermoelectric properties of the layered cobalt oxide system LixCoO2 were investigated in a wide range of Li composition, 0.98 >= x >= 0.35. Single-phase bulk samples of LixCoO2 we…
A quantum no-reflection theorem and the speeding up of Grover's search algorithm
Karthikeyan S. Kumar, G. S. Paraoanu
We prove that it is impossible to built a universal quantum machine that produces reflections about an unknown state. We then point out a connection between this result and the opt…
Partial measurements and the realization of quantum-mechanical counterfactuals
G. S. Paraoanu
We propose partial measurements as a conceptual tool to understand how to operate with counterfactual claims in quantum physics. Indeed, unlike standard von Neumann measurements, p…
