High-speed quantum transducer with a single-photon emitter in a 2D resonator
Xingyu Gao, Zhang-qi Yin, Tongcang Li
Quantum transducers can transfer quantum information between different systems. Microwave-optical photon conversion is important for future quantum networks to interconnect remote…
Experimental realization of Feynman's ratchet
Jaehoon Bang, Rui Pan, Thai M. Hoang +4
Feynman's ratchet is a microscopic machine in contact with two heat reservoirs, at temperatures and , that was proposed by Richard Feynman to illustrate the second law o…
Symmetry-breaking dynamics of the finite-size Lipkin-Meshkov-Glick model near ground state
Yi Huang, Tongcang Li, Zhang-qi Yin
We study the dynamics of the Lipkin-Meshkov-Glick (LMG) model with finite number of spins. In the thermodynamic limit, the ground state of the LMG model with isotropic Hamiltonian…
Quantum calculation of feedback cooling a laser levitated nanoparticle in the shot-noise-dominant regime
Changchun Zhong, Tongcang Li, F. Robicheaux
In this paper, results of quantum calculations are presented for feedback cooling of an optically trapped nanoparticle in the laser-shot-noise-dominant regime. We numerically inves…
Experimental test of the differential fluctuation theorem and a generalized Jarzynski equality for arbitrary initial states
Thai M. Hoang, Rui Pan, Jonghoon Ahn +3
Nonequilibrium processes of small systems such as molecular machines are ubiquitous in biology, chemistry and physics, but are often challenging to comprehend. In the past two deca…
Detecting Casimir torque with an optically levitated nanorod
Zhujing Xu, Tongcang Li
The linear momentum and angular momentum of virtual photons of quantum vacuum fluctuations can induce the Casimir force and the Casimir torque, respectively. While the Casimir forc…
