Magnetic resonance wireless power transfer (WPT) has emerged as a pivotal technology for near-field electromagnetic manipulation, enabling wire-free energy delivery across diverse applications ranging from consumer electronics and implantable medical devices to electric vehicles. While near-field coupling facilitates this paradigm shift, it imposes inherent constraints: the exponential decay of coupling strength fundamentally limits transfer distance to short-to-mid ranges, and complex

By using both diagrammatic theory and Chevy ansatz approach, we derive an exact set of equations, which determines the spectral function of Fermi polarons with multiple particle-hole excitations at nonzero temperature. In the diagrammatic theory, we find out the complete series of Feynman diagrams for the multi-particle vertex functions, when the unregularized contact interaction strength becomes infinitesimal, a typical situation occurring in two- or three-dimensional free space. The

We attempt to propose the first orthogonal-state-based protocols of measurement-device-independent quantum secure direct communication and quantum dialogue employing single basis, i.e., Bell basis as decoy qubits for eavesdropping detection. Orthogonal-state-based protocols are inherently distinct from conventional conjugate-coding protocols, offering unconditional security derived from the duality and monogamy of entanglement. Noise imposes a major challenge to the efficient implement

The National Array of Neutron Detectors (NAND) at IUAC is one of the big detector arrays used in experiments to study nuclear fission through the measurement of the neutrons emitted during the process. The array is installed at IUAC heavy ion accelerator facility. NAND consists of 100 liquid scintillators mounted on a semi-spherical geometry covering a total of 3.3\(\%\) of 4\(\pi\) solid angle. The 175-cm-long flight path provides good energy resolution of the emitted neutrons, enabli

The originally private notes below were posted in March 2022, for the purpose to make them available to interested parties in a public-domain way, and not intended to be submitted for publications [1]. As such, it was the first publication exploring interplay between altermagnetism and superconductivity. The editors of this Special Issue suggested to use it as a brief introduction; this make sense from the history point of view, so it is being published here in an unaltered form, and no attempt

Non-equilibrium dynamics have become a central research focus, exemplified by the counterintuitive Mpemba effect where initially hotter systems can cool faster than colder ones. Studied extensively in both classical and quantum regimes, this phenomenon reveals diverse and complex behaviors across different systems. This review provides a concise overview of the quantum Mpemba effect (QME), specifically emphasizing its connection to symmetry breaking and restoration in closed quantum ma

The study of strongly correlated electron systems remains a fundamental challenge in condensed matter physics, particularly in two-dimensional (2D) systems hosting various exotic phases of matter including quantum spin liquids, unconventional superconductivity, and topological orders. Although Density Matrix Renormalization Group (DMRG) has established itself as a pillar for simulating one-dimensional quantum systems, its application to 2D systems has long been hindered by the notoriou

As two-dimensional (2D) semiconductor devices demand ever higher performance and tunable photo-energy responses, the ability to probe and control exciton-trion interconversion has attracted much attention. However, conventional optical studies predominantly rely on far-field schemes, which suffer from inherent limitations, such as low spatial resolution and weak photoluminescence signals, restricting practical applications. To address these challenges, plasmonic structures have been em

Precision measurements and reliable predictions of nuclear masses are pivotal in advancing nuclear physics and astrophysics. In this paper, we review recent progress in constructing a microscopic nuclear mass table based on the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) that simultaneously incorporates deformation and continuum effects. We present the predictive power and accuracy of the DRHBc mass table, highlighting its diverse applications and extensions. W

The quest to unravel the intricacies of high-Tc superconductivity and strongly correlated electrons in cuprates has spurred a novel focus on direct probing of the CuO2 planes through scanning tunneling microscopy. Infinite-layer (IL) cuprates, featuring a CuO2-terminated surface, emerge as optimal systems for this investigation. Leveraging controllable growth via molecular beam epitaxy, both electron- and hole-doped IL cuprates are realized, with surface structure and c-axis length ser
