The Cluster Shell Model (CSM)describes light nuclei in terms of $k-\alpha$ particles and $x$ extra nucleons, in which the extra nucleon move in the deformed field generated by the geometric configuration of $\alpha$-particles. We present the first study for the case $x=2$ nucleons in application to $^{10}Be$ as a clust... | https://arxiv.org/abs/2309.14505v1 |
We present a determination of optical potentials for $^{10}$Be-nucleus collisions using the double-folding method to compute the real part and Kramers-Kronig dispersion relations to derive the imaginary part. As microscopic inputs we use chiral effective field theory nucleon-nucleon interactions at next-to-next-to-lead... | https://arxiv.org/abs/2205.13987v2 |
Significant suppression of radiation in 3D structured media with small refractive index 1.4-1.6, such as of glass or polymers, is a desirable feature yet to be obtained. For periodical structures this is realised at frequencies of the complete photonic band gap (CPBG), which up to now was demonstrated to open for mater... | https://arxiv.org/abs/2209.15463v1 |
We remark that the two 10D massive deformations of the $N=2$ maximal type IIA
supergravity (Romans and HLW supergravity) are associated to the low energy
limit of the uplift to 10D of M2-brane torus bundles with parabolic monodromy
linearly and non-linearly realized respectively. Romans supergravity
corresponds to M2-b... | http://arxiv.org/abs/1511.04784v1 |
Using the pure spinor master action for 10D super-Yang-Mills in the gauge $b_{0}V = Q\Xi$, tree-level scattering amplitudes are calculated through the perturbiner method, and shown to match those obtained from pure spinor CFT techniques. We find kinematic numerators made of nested $b$-ghost operators, and show that the... | https://arxiv.org/abs/2108.11708v1 |
We dimensionally reduce the bosonic sector of 10D Euclidean type IIA
supergravity over a Calabi-Yau three-fold. The resulting theory describes the
bosonic sector of 4D, N = 2 Euclidean supergravity coupled to vector- and
hyper-multiplets.
We show that the scalar target manifold of the vector-multiplets is
projective ... | http://arxiv.org/abs/1503.05095v3 |
The realization of high-frequency unipolar quantum optoelectronic devices enables the demonstration of high bitrate free space data transmission in the second atmospheric window. Data-bits are written onto the laser emission using a large bandwidth amplitude modulator that operates by shifting the absorption of an opti... | https://arxiv.org/abs/2110.06572v1 |
A coherent XY machine (CXYM) is a physical spin simulator that can simulate the XY model by mapping XY spins onto the continuous phases of non-degenerate optical parametric oscillators (NOPOs). Here, we demonstrated a large-scale CXYM with >47,000 spins by generating 10-GHz-clock time-multiplexed NOPO pulses via four-w... | https://arxiv.org/abs/2307.03333v2 |
Coherent frequency division of high-stability optical sources permits the extraction of microwave signals with ultra-low phase noise, enabling their application to systems with stringent timing precision. To date, the highest performance systems have required tight phase stabilization of laboratory grade optical freque... | https://arxiv.org/abs/2110.00593v1 |
In practical satellite-based quantum key distribution (QKD) systems, the preparation and transmission of polarization-encoding photons suffer from complex environmental effects and high channel-loss. Consequently, the hinge to enhancing the secure key rate (SKR) lies in achieving robust, low-error and high-speed polari... | https://arxiv.org/abs/2411.08358v1 |
Generation of quantum light source is a promising technique to overcome the standard quantum limit in precision measurement. Here, we demonstrate an experimental generation of quadrature squeezing resonating on the cesium D2 line down to 10 Hz for the first time. The maximum squeezing in audio frequency band is 5.57 dB... | https://arxiv.org/abs/2209.07920v3 |
We propose a novel procedure to generate pseudo mandarin speech data named as CAMP (character audio mix up), which aims at generating audio from a character scale. We also raise a method for building a mandarin character scale audio database adaptive to CAMP named as META-AUDIO, which makes full use of audio data and c... | https://arxiv.org/abs/2210.13067v1 |
The widespread deployment of InfRared Small-Target Detection(IRSTD) algorithms on edge devices necessitates the exploration of model compression techniques. Binary neural networks (BNNs) are distinguished by their exceptional efficiency in model compression. However, the small size of infrared targets introduces string... | https://arxiv.org/abs/2503.02662v1 |
We consider the integers having the property of reversing when multiplied by
a specific integer k. First, we proved that k should be either 1, 4 or 9.
Second, we classify these integers as (10, 1)- reverse multiples, (10, 4)-
reverse multiples and (10, 9)- reverse multiples. Then we conclude their
general form. | http://arxiv.org/abs/1503.07848v2 |
Fix a planar graph $G$ and a list-assignment $L$ with $|L(v)|=10$ for all $v\in V(G)$. Let $\alpha$ and $\beta$ be $L$-colorings of $G$. A recoloring sequence from $\alpha$ to $\beta$ is a sequence of $L$-colorings, beginning with $\alpha$ and ending with $\beta$, such that each successive pair in the sequence differs ... | https://arxiv.org/abs/2411.00679v2 |
We report the first quantum key distribution (QKD) systems capable of
delivering sustainable, real-time secure keys continuously at rates exceeding
10 Mb/s. To achieve such rates, we developed high speed post-processing
modules, achieving maximum data throughputs of 60 MC/s, 55 Mb/s, and 108 Mb/s
for standalone operati... | http://arxiv.org/abs/1807.04484v1 |
High resolution images are widely used in our daily life, whereas high-speed video capture is challenging due to the low frame rate of cameras working at the high resolution mode. Digging deeper, the main bottleneck lies in the low throughput of existing imaging systems. Towards this end, snapshot compressive imaging (... | https://arxiv.org/abs/2106.15765v2 |
