A new five-dimensional fractional-order laser chaotic system (FOLCS) is constructed by incorporating complex vari-ables and fractional calculus into a Lorentz-Haken-type laser system.Dynamical behavior of the system,circuit realization and application in pseudorandom number generators are studied.Many types of multi-stable states are discovered in the system.Interestingly,there are two types of state transition phenomena in the system,one is the chaotic state degenerates to a periodical state,and the other is the intermittent chaotic oscillation.In addition,the complexity of the system when two parameters change simultaneously is measured by the spectral entropy algorithm.Moreover,a digital circuit is design and the chaotic oscillation behaviors of the system are verified on this circuit.Finally,a pseudo-random sequence generator is designed using the FOLCS,and the statistical characteristics of the generated pseudo-random sequence are tested with the NIST-800-22.This study enriches the research on the dynamics and applications of FOLCS.

We study dynamical behaviors of a Bose-Einstein condensate (BEC) containing a dark soliton reflected from potential wells and potential barriers,respectively.The orientation angle of the dark soliton and the width of the potential change play key roles on
Monolayer MnTe2 stabilized as 1T structure has been theoretically predicted to be a two-dimensional (2D) ferromag-netic metal and can be tuned via strain engineering.There is no naturally van der Waals (vdW) layered MnTe2 bulk,leaving mechanical exfoliati
Quantum coherence and discord are two kinds of manifestations of nonclassicality.By calculating the coherence and discord in the specific bipartite quantum systems,we show quantitative connections between the coherence and the discord in the bipartite qua
We numerically study the interaction dynamics of two bright solitons with zero initial velocities in the one-dimensional dipolar Bose-Einstein condensates.Under different dipolar strengths,the two bright solitons can merge into a breathing wave,and then s

We present a three-party reference frame independent quantum key distribution protocol which can be implemented without any alignment of reference frames between the sender and the receiver.The protocol exploits entangled states to establish a secret key
LIGO-Virgo has observed the gravitational waves (GWs) from the coalescence of binary black hole (BBH) and binary neutron star (BNS) during O1 and O2,and the ones from NS-BH are expected to be hunted in the operating O3 run.The population properties and ma
In most practical quantum mechanical systems,quantum noise due to decoherence is highly biased towards dephas-ing.The quantum state suffers from phase flip noise much more seriously than from the bit flip noise.In this work,we construct new families of as
