Evidence of shallow bandgap in ultra-thin 1T'-MoTe2 via infrared spectroscopy
Jin Cheol Park, Eilho Jung, Sangyun Lee +2
Although van der Waals (vdW) layered MoS2 shows the phase transformation from the semiconducting 2H-phase to the metallic 1T-phase through chemical lithium intercalation, vdW MoTe2…
Inertial effects on the Brownian gyrator
Youngkyoung Bae, Sangyun Lee, Juin Kim +1
The recent interest into the Brownian gyrator has been confined chiefly to the analysis of Brownian dynamics both in theory and experiment despite the applicability of general case…
Quantumness and thermodynamic uncertainty relation of finite-time Otto cycle
Sangyun Lee, Meesoon Ha, Hawoong Jeong
To reveal the role of the quantumness in the Otto cycle and to discuss the validity of the thermodynamic uncertainty relation (TUR) in the cycle, we study the quantum Otto cycle an…
Learning entropy production via neural networks
Dong-Kyum Kim, Youngkyoung Bae, Sangyun Lee +1
This Letter presents a neural estimator for entropy production, or NEEP, that estimates entropy production (EP) from trajectories of relevant variables without detailed information…
Finite-time quantum Otto engine: Surpassing the quasi-static efficiency due to friction
Sangyun Lee, Meesoon Ha, Jong-Min Park +1
In finite-time quantum heat engines, some work is consumed to drive a working fluid accompanying coherence, which is called `friction'. To understand the role of friction in quantu…
Quantum mechanical bound for efficiency of quantum Otto heat engine
Jong-Min Park, Sangyun Lee, Hyun-Myung Chun +1
The second law of thermodynamics constrains that the efficiency of heat engines, classical or quantum, cannot be greater than the universal Carnot efficiency. We discover another b…
