Summary: In this study, a method is proposed to achieve a coherent switch of optomechanical entanglement in an optical whispering-gallery-mode resonator by tuning the phase difference of the driving lasers. It is found that the optomechanical entanglement and the associated two-mode quantum squeezing can be well tuned in a highly asymmetric way, providing an efficient method to protect and enhance quantum entanglement against optical backscattering. This research sheds new light on improving the performance of various quantum devices in practical noisy environments, which is crucial for applications such as noise-tolerant quantum processing and backscattering-immune quantum metrology.

Summary: Long-range Rydberg interactions combined with EIT can produce strongly interacting photons with tunable and controllable strength, sign, and form of the interactions, allowing for the generation of novel few-photon states. It has been shown that in the Rydberg-EIT system, three-body interactions can be as strong or stronger than two-body interactions. The observed features in the outgoing photonic correlations are strongly suggested to be caused by the resonant enhancement of three-body losses based on numerical simulations and analytical estimates.

Summary: In the past decade, a new research frontier called inelastic thermoelectric effects has emerged at the interface between physics and renewable energy. This field broadens our understanding of thermoelectric phenomena and offers new pathways for high-performance thermoelectric energy conversion. The main progress in this field, particularly in regards to inelastic thermoelectric effects induced by electron-phonon and electron-photon interactions, is reviewed. The unconventional effects induced by inelastic thermoelectric transport, including heat and charge transport separation, cooling by heating effect, linear thermal transistor effect, nonlinear enhancement of performance, Maxwell demons, and cooperative effects, are also discussed. The microscopic mechanisms and linear thermodynamic classes of elastic and inelastic thermoelectric effects are found to be significantly different. The unique aspect of fluctuations in small mesoscopic thermoelectric systems is also highlighted. Lastly, the challenges and future opportunities in the field of inelastic thermoelectrics are addressed.

Summary: In this study, the chirality of hydrothermally grown 2D Te is identified and analyzed, and gate-tunable nonlinear electrical responses are observed in 2D Te under a magnetic field, with opposite signs in left- and right-handed 2D Te due to the chiral symmetry. The fundamental relationship between spin-orbit coupling and crystal symmetry in two enantiomers provides a viable platform for chirality-based electronic devices.

Summary: This study proposes a superior electric-controlled thermal switch (ECTS) based on Janus monolayer MoSSe, which can effectively and widely regulate thermal conductivity. The underlying mechanism is revealed by electronic structures, showing interactions between electrons and phonons are renormalized due to charge density redistribution driven by electric fields, ultimately modulating phonon anharmonicity. This highly efficient and adjustable ECTS component is expected to provide new inspiration for next-generation thermal management and information processing.

Summary: This study investigates the electrically controllable quantum coherence in quantum dot clusters and arrays based on graphene stripes with zigzag atomic edges. The researchers demonstrate that the coherence time of multiqubit circuits can be significantly prolonged by intrinsic spectral narrowing in adjacent sections, enabling stable operation at room temperature. Moreover, the technique of Stark splitting allows for a wide range of operations including tuning energy level positions and widths, controlling level splitting and interqubit coupling, and enhancing coherence time. These findings have potential applications in quantum computing and communication at room temperature.

Summary: This paper investigates properties of continuous time chiral quantum walks with complex valued edge weights in certain graph topology, and designs a quantum walk graph analogue of an optical circulator. It examines in detail how excitations are routed in a directionally biased fashion from one semi-infinite chain to another in the circulator graph setup.

Summary: We theoretically investigate the scattering properties of single photons in a waveguide chirally coupled to a giant atom. When considering the energy loss of the giant atom, the transmission spectrum of a single photon depends on its incident direction. We calculate the difference in transmission probabilities for opposite transport directions, denoted as Delta T. It is found that the position and width of Delta T are both dependent on the size of the giant atom. Furthermore, the position and frequency width of the maximum Delta T can be modulated by a classical laser beam. Our findings are relevant for the control of single photons in the design of quantum devices involving giant atoms.

Summary: The researchers discovered the imaginary and real parts, namely the Berry curvature and quantum metric, respectively, of the quantum geometric tensor that characterizes the topology of quantum states. By observing in thin films of a topological antiferromagnet, MnBi2Te4, they found the nonlinear transport phenomena induced by the quantum metric, including the nonlinear anomalous Hall effect and diode-like response. These findings provide a means to probe the quantum metric through nonlinear transport and to design magnetic nonlinear devices.
