Heat Transfer and Torque in Enclosing Cylindrical Configurations with Nonreciprocal Materials
Dhruv Shah, Kiryl Asheichyk, David Gelbwaser-Klimovsky +3
Electromagnetic fluctuations can transfer not only energy but also angular momentum, leading to forces, torques, heat currents, and friction in out-of-equilibrium setups. In enclos…
A Contactless Heat Engine Driven by Nonreciprocal Fluctuation-Induced Torques
Dhruv Shah, Kiryl Asheichyk, David Gelbwaser-Klimovsky +3
We describe a contactless heat engine in which quantum and thermal electromagnetic fluctuations act as the working medium. The setup consists of two concentric cylinders held at di…
Propulsion force and heat transfer for nonreciprocal nanoparticles
Laila Henkes, Kiryl Asheichyk, Matthias Krüger
We analyze heat transfer and Casimir forces involving a nonreciprocal nanoparticle. By dissecting the resulting expressions into reciprocal and nonreciprocal contributions, we find…
Time-dependent radiative heat flux after the beginning of thermal radiation
Kiryl Asheichyk
We develop a theoretical formalism for time-dependent radiative heat flux from one object to another in the case where the former starts radiating at a certain time. The time depen…
Heat radiation and transfer for nanoparticles in the presence of a cylinder
Kiryl Asheichyk, Matthias Krüger
We study heat radiation and radiative heat transfer for nanoparticles in the presence of an infinitely long cylinder in different geometrical configurations, based on its electroma…
Scale-dependent heat transport in dissipative media via electromagnetic fluctuations
Matthias Krüger, Kiryl Asheichyk, Mehran Kardar +1
We develop a theory for heat transport via electromagnetic waves inside media, and use it to derive a spatially nonlocal thermal conductivity tensor, in terms of the electromagneti…
Long-range super-Planckian heat transfer between nanoemitters in a resonant cavity
Kiryl Asheichyk, Philippe Ben-Abdallah, Matthias Krüger +1
We study radiative heat transfer between two nanoemitters placed inside different types of closed cavities by means of a fluctuational-electrodynamics approach. We highlight a very…
Radiative heat transfer with a cylindrical waveguide decays logarithmically slow
Kiryl Asheichyk, Matthias Krüger
Radiative heat transfer between two far-field-separated nanoparticles placed close to a perfectly conducting nanowire decays logarithmically slow with the interparticle distance. T…
Brownian systems perturbed by mild shear: Comparing response relations
Kiryl Asheichyk, Matthias Fuchs, Matthias Krüger
We present a comprehensive study of the linear response of interacting underdamped Brownian particles to simple shear flow. We collect six different routes for computing the respon…
Using the fluctuation-dissipation theorem for nonconservative forces
Kiryl Asheichyk, Matthias Krüger
An equilibrium system which is perturbed by an external potential relaxes to a new equilibrium state, a process obeying the fluctuation-dissipation theorem. In contrast, perturbing…
Response of active Brownian particles to shear flow
Kiryl Asheichyk, Alexandre P. Solon, Christian M. Rohwer +1
We study the linear response of interacting active Brownian particles in an external potential to simple shear flow. Using a path integral approach, we derive the linear response o…
Heat radiation and transfer in confinement
Kiryl Asheichyk, Matthias Krüger
Near-field heat radiation and transfer are rich in various exciting effects, in particular, regarding the amplification due to the geometrical configuration of the system. In this…
Heat radiation and transfer for point particles in arbitrary geometries
Kiryl Asheichyk, Boris Müller, Matthias Krüger
We study heat radiation and heat transfer for pointlike particles in a system of other objects. Starting from exact many-body expressions found from scattering theory and fluctuati…
