The Type-II/Type-I Crossover in Dirty Ferromagnetic Superconductors
P. M. Marychev, Yajiang Chen
In this work we investigate the intertype (IT) domain in strongly disordered ferromagnetic superconductors with a Curie temperature lower than the superconducting critical temperat…
Surface superconductor-insulator transition: Reduction of the critical electric field by Hartree-Fock potential
Yajiang Chen, Quanyong Zhu, Ming Zhang +2
Recently, a surface superconductor-insulator transition has been predicted for a bulk superconductor in an electric field applied perpendicular to its surface. The related calculat…
Tailoring of the interference-induced surface superconductivity by an applied electric field
Yunfei Bai, Libo Zhang, Xiaobing Luo +2
Nucleation of the pair condensate near surfaces above the upper critical magnetic field and the pair-condensate enhancement/suppression induced by changes in the electron-phonon in…
Non-gapless excitation and zero-bias fast oscillations in the LDOS of surface superconducting states
Liangyuan Chen, Yajiang Chen, Zhang Wenhui +1
Recently a novel surface pair-density-wave (PDW) superconducting state has been discovered in Refs. [Phys. Rev. Lett. \textbf{122}, 165302 (2019)] and Phys. Rev. B \textbf{101}, 05…
Novel -type vortex in a nanoscale extreme type-II superconductor: Induced by quantum-size effect
Haiyan Huang, Qing Liu, Wenhui Zhang +1
By numerically solving the Bogoliubov-de Gennes equations, we report a novel -type vortex state whose order parameter near the core undergoes an extraordinary -phase change f…
Surface superconductor-insulator transition induced by an electric field
Liyu Yin, Yunfei Bai, Ming Zhang +2
It is well-known that the electric field can induce phase transitions between superconducting, metallic and insulating states in thin-film materials due to its control of the charg…
Ratchet current in a -symmetric Floquet quantum system with symmetric sinusoidal driving
Zhiqiang Li, Xiaoxiao Hu, Jinpeng Xiao +2
We consider the ratchet dynamics in a -symmetric Floquet quantum system with symmetric temporal (harmonic) driving. In the exact phase, for a finite nu…
Scattering of one-dimensional quantum droplets by a reflectionless potential well
Xiaoxiao Hu, Zhiqiang Li, Yu Guo +2
We investigate, both analytically and numerically, the scattering of one-dimensional quantum droplets by a Pöschl-Teller reflectionless potential well, confirming that there is a s…
Interference-induced surface superconductivity:Enhancement by tuning the Debye energy
Yunfei Bai, Yajiang Chen, M. D. Croitoru +3
In the usual perception, surface superconductivity is associated with the surface nucleation of a superconducting condensate above the upper critical field in type-II superconducto…
