The coherence peak of unconventional superconductors in the charge channel
Pengfei Li, Zheng Li, Kun Jiang
In this work, we carry out a systematic investigation of the coherence peak in unconventional superconductors as they transition into the superconducting phase at . Using -…
Unconventional Coherence Peak in Cuprate Superconductors
Zheng Li, Chao Mu, Pengfei Li +5
The Hebel-Slichter coherence peak, observed in the spin-lattice relaxation rate just below the critical temperature , serves as a crucial experimental validation…
Bound states in doped charge transfer insulators
Pengfei Li, Yang Shen, Mingpu Qin +3
Understanding the physics of doped charge transfer insulators is the most important problem in high-temperature superconductivity. In this work, we show that an in-gap bound state…
Tunable vortex bound states in multiband CsV3Sb5-derived kagome superconductors
Zihao Huang, Xianghe Han, Zhen Zhao +12
Vortices and bound states offer an effective means of comprehending the electronic properties of superconductors. Recently, surface dependent vortex core states have been observed…
Paramagnetic contribution in superconductors with different-mass Cooper pairs
Pengfei Li, Kun Jiang, Jiangping Hu
Cooper pairs formed by two electrons with different effective masses are common in multiband superconductors, pair density wave states, and other superconducting systems with multi…
Correlated BCS wavefunction approach to unconventional superconductors
Pengfei Li, Kun Jiang, Jiangping Hu
We propose a modified BCS wavefunction as the ground state of a correlated superconductor with the correlation specified between and electrons in the reciprocal space. Owi…
