“…One should study the competition and coexistence effect between the different orders to determine the final phase diagram of the system. Some previous studies already focused on this kind of holographic systems and produced many interesting results [12, 13, 14, 15, 16, 17, 18, 19, 20, 21, a e-mail:niezy@kmust.edu.cn b e-mail:panqiyuan@126.com c e-mail:zenghbi@gmail.com d e-mail:zenghui@kmust.edu.cn Correspondence to: Zhang-Yu Nie 22, 23,24,25].

In this paper, we investigate the p+ip superfluid phases in the complex vector field holographic p-wave model. We find that in the probe limit, the p+ip phase and the p-wave phase are equally stable, hence the p and ip orders can be mixed with an arbitrary ratio to form more general p+λip phases, which are also equally stable with the p-wave and p+ip phases. As a result, the system possesses a degenerate thermal state in the superfluid region. We further study the case on considering the back-reaction on the metric, and we find that the degenerate ground states will be separated into pwave and p+ip phases, and the p-wave phase is more stable. Finally, due to the different critical temperature of the zeroth order phase transitions from p-wave and p+ip phases to the normal phase, there is a temperature region where the p+ip phase exists but the p-wave phase does not. In this region we find the stable holographic p+ip phase for the first time.

In this work, we propose a toy model for mixture of superconductors with competitive s and p modes using gauge/gravity duality. We demonstrate that the model undergoes phase transitions with the proper choice of different values for chemical potentials. We consider both balanced and unbalanced cases. We propose that the condensate field in the bulk toy model for a mixing s+p phase of high temperature superconductors undergoes a chaotic phase space scenario. Using a suitable measure function for chaos, we demonstrate the existence of chaotic dynamics via condensate fields. As an alternative method, we also investigate the phase portrait in the extended phase space for the condensates.

“…Moreover, we have also known the endogenous fluorescence of BSA can be quenched by sucrose through the H-bond interaction. [30,31] For further elucidating the existence of H-Bond interaction, the replacement experiments of sucrose with PPF on BSA were performed. The results revealed that the reduction in the ratio in the fluorescence intensity in the BSA and sucrose system was lower than that in BSA alone, or the decrease in the K SV value in the BSA and sucrose system was lower than that in BSA alone, implying that sucrose occupies the active site of BSA that provides hydrogen bonding interaction, resulting in the effect on the binding interaction between PPF and BSA.…”

The investigation on the interaction mechanism between pesticide pyriproxyfen (PPF) and serum albumin has great implications in clinical detection, gene mutation and pathological analysis of pesticide poisoning. In this paper, the binding behavior of PPF with bovine serum albumin (BSA) have been assessed through various spectroscopic techniques combined with computer simulation. The findings confirmed that PPF quenched the endogenous fluorescence of BSA in the means of static quenching and formed the stable PPF‐BSA complex with the stoichiometry of 1:1. The affinity of PPF on BSA was moderate due to its binding constant of 4.15×103 M−1 (298 K). It was confirmed from replacement experiments and molecular docking that PPF bound preferentially onto the Site I region of BSA. The findings from thermodynamic parameter analysis and the replacement experiments of ANS and sucrose confirmed the driving‐forces for forming PPF‐BSA complex was hydrogen bonding, van der Waals and hydrophobic interactions. Meantime, it was also confirmed from synchronous fluorescence and FT‐IR spectra that the hydrophilicity surrounding Trp residues and α‐helix of BSA declined due to binding with PPF. And, it is confirmed from in silico finding the dipole moment, atomic charge distribution, molecular conformation, and frontier orbital of PPF also significantly altered after binding with BSA.
