Universal Scaling Bounds on a Quantum Heat Current
Shunsuke Kamimura, Kyo Yoshida, Yasuhiro Tokura +1
We derive new bounds on a heat current flowing into a quantum -particle system coupled with a Markovian environment. By assuming that a system Hamiltonian and a system-environme…
Quantum battery based on superabsorption
Yudai Ueki, Shunsuke Kamimura, Yuichiro Matsuzaki +2
A quantum battery is a device where an energy is charged by using a quantum effect. Here, we propose a quantum battery with a charger system composed of qubits by utilizing a c…
Quantum-Enhanced Heat Engine Based on Superabsorption
S. Kamimura, H. Hakoshima, Y. Matsuzaki +2
We propose a quantum-enhanced heat engine with entanglement. The key feature of our scheme is superabsorption, which facilitates enhanced energy absorption by entangled qubits. Whe…
