The formation of a topological superconducting phase in quantum-dot--based Kitaev chain requires nearest neighbor crossed Andreev reflection and elastic cotunneling. Here, we report on hybrid InSb nanowire three-site geometry---the smallest system with well-defined bulk edge---where two superconductor-semiconductor hybrids separate three quantum dots. We demonstrate pairwise cotunneling between both pairs neighboring dots show sequential tunneling processes involving all These results are...
Dissipaton theory had been proposed as an exact, nonperturbative approach to deal with open quantum system dynamics, where the influence of Gaussian environment is characterized by statistical quasi-particles, named dissipatons. In this work, we revisit dissipaton equation motion and establish equivalent dissipaton-embedded master (DQME) that gives rise dissipatons generalized Brownian particles. As explained in DQME supplies a direct investigate characteristics and, thus, physically...
As quantum technologies continue to advance, the simulation of open dynamics using algorithms has garnered increasing attention. In this paper, we present a universal and compact theory, dissipaton-embedded master equation in second quantization (DQME-SQ), for simulating non-Markovian dynamics. The DQME-SQ theory is not only inprinciple exact both bosonic fermionic environments that satisfy Gaussian statistics, but also possesses form facilitates simulations. To demonstrate practicality...
A conventional resonant detector is often subject to a trade-off between bandwidth and peak sensitivity. Anomalous dispersion has been shown improve the bandwidth-sensitivity limit by signal amplification, but its unstable issue in operation needs additional feedback control. Here we propose stable quantum amplifier enabled two-mode non-degenerate parametric amplification. As operates at threshold, one mode of forms parity-time(PT)-symmetric system with original detector, while other...
Spontaneous emission measurements, as a function of injection current and temperature, were carried out from the sidewall working 2 µm InGaSb/AlGaAsSb quantum well laser. The local Z power parameter was extracted to investigate carrier recombination behaviors. A model involving activation energy is presented interpret loss mechanisms. Our findings show that majority injected carriers recombine radiatively at low currents, Auger nonradiative increases significantly with current. More...
Several control schemes have been proposed for optical tweezers, but most existing methods assume that the trapping is maintained throughout manipulation, and Brownian motion ignored simplification of stability analysis. However, not effective when a biological cell initially outside trap, even if trapped, it may escape from trap due to random perturbations kinetic energy gained during manipulation. This paper presents new robotic technique address manipulation problem in presence...
We determine the hydrodynamic relaxation times $\tau_\eta$ for shear viscosity and $\tau_\kappa$ thermal conductivity in normal phase of a unitary Fermi gas confined box potential. Using kinetic theory model, we extract from time-dependent free-decay spatially periodic density perturbation, yielding universal density-shift coefficients conductivity.
A conventional resonant detector is often subject to a trade-off between bandwidth and peak sensitivity that can be traced back quantum Cramer-Rao Bound. Anomalous dispersion has been shown improve it by signal amplification thus more robust against decoherence, while leads instabilities. We propose stable amplifier applicable linear systems operating at the fundamental detection limits, enabled two-mode non-degenerate parametric amplification. At threshold, one mode of forms PT-symmetric...

This paper studies a traceable anti-counterfeiting technology by adding small amount of rare earth oxides to the printer toner. Different types and contents are added toners, relatively independent characteristic spectral lines can be obtained in analysis their prints. Based on toner prints different oxides, database established. The spectrum detection system adopts infrared spectrometer, uses wavelet transform support vector machine process classify data.
We measure the free decay of a spatially periodic density profile in normal fluid strongly interacting Fermi gas, which is confined box potential.This spatial initially created thermal equilibrium by perturbing potential.After perturbation abruptly extinguished, dominant Fourier component exhibits an exponentially decaying (thermally diffusive) mode and oscillatory (first sound) mode, enabling independent measurement conductivity shear viscosity directly from time-dependent evolution.
The kilo-Hertz gravitational waves radiated by the neutron star merger remnants carry rich information about physics of high-density nuclear matter states, and many important astrophysical phenomena such as gamma-ray bursts black hole formation. Current laser interferometer wave detectors, LIGO, VIRGO, KAGRA have limited signal response at band, thereby unable to capture these physical phenomena. This work proposes an alternative protocol for boosting sensitivity detectors high frequency...
