Multidimensional entropic bound: Estimator of entropy production for general Langevin dynamics with an arbitrary time-dependent protocol
Sangyun Lee, Dong-Kyum Kim, Jong-Min Park +3
Entropy production (EP) is a key quantity in thermodynamics, and yet measuring EP has remained a challenging task. Here we introduce an EP estimator, called multidimensional entrop…
Universal form of thermodynamic uncertainty relation for Langevin dynamics
Jae Sung Lee, Jong-Min Park, Hyunggyu Park
Thermodynamic uncertainty relation (TUR) provides a stricter bound for entropy production (EP) than that of the thermodynamic second law. This stricter bound can be utilized to inf…
Thermodynamic uncertainty relation in the overdamped limit with a magnetic Lorentz force
Jong-Min Park, Hyunggyu Park
In nonequilibrium systems, the relative fluctuation of a current has a universal trade-off relation with the entropy production, called the thermodynamic uncertainty relation (TUR)…
Geometry-induced rectification for an active object
Jae Sung Lee, Jong-Min Park, Jae Dong Noh +1
Study on a rectified current induced by active particles has received a great attention due to its possible application to a microscopic motor in biological environments. Insertion…
Brownian heat engine with active reservoirs
Jae Sung Lee, Jong-Min Park, Hyunggyu Park
Microorganisms such as bacteria are active matters which consume chemical energy and generate their unique run-and-tumble motion. A swarm of such microorganisms provide a nonequili…
Exactly solvable two-terminal heat engine with asymmetric Onsager coefficients: Origin of the power-efficiency bound
Jae Sung Lee, Jong-Min Park, Hyun-Myung Chun +2
An engine producing a finite power at the ideal (Carnot) efficiency is a dream engine, which is not prohibited by the thermodynamic second law. Some years ago, a two-terminal heat…
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…
Thermodynamic uncertainty relation for underdamped Langevin systems driven by a velocity-dependent force
Jae Sung Lee, Jong-Min Park, Hyunggyu Park
Recently, it has been shown that there is a trade-off relation between thermodynamic cost and current fluctuations, referred to as the thermodynamic uncertainty relation (TUR). The…
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…
Creating small circular, elliptical, and triangular droplets of quark-gluon plasma
C. Aidala, Y. Akiba, M. Alfred +316
The experimental study of the collisions of heavy nuclei at relativistic energies has established the properties of the quark-gluon plasma (QGP), a state of hot, dense nuclear matt…
Tricritical behavior of nonequilibrium Ising spins in fluctuating environments
Jong-Min Park, Jae Dong Noh
We investigate the phase transitions in a coupled system of Ising spins and a fluctuating network. Each spin interacts with neighbors through links of the rewiring network. The…
Efficiency at maximum power and efficiency fluctuations in a linear Brownian heat engine model
Jong-Min Park, Hyun-Myung Chun, Jae Dong Noh
We investigate stochastic thermodynamics of a two-particles Langevin system. Each particle is in contact with a heat bath at different temperatures and , respecti…
Optimal tuning of a confined Brownian information engine
J. -M. Park, J. S. Lee, J. D. Noh
A Brownian information engine is a device extracting a mechanical work from a single heat bath by exploiting the information on the state of a Brownian particle immersed in the bat…
Fluctuation Relation for Heat
Jae Dong Noh, Jong-Min Park
We present a fluctuation relation for heat dissipation in a nonequilibrium system. A nonequilibrium work is known to obey the fluctuation theorem in any time interval . A heat,…
