▼a Complex physical phenomena, such as superconductivity, colossal magnetoresistance (CMR) effect, multi-ferroics, metal-insulator transition, quantum phase transition, etc. in strongly correlated materials have been enduring topics in condensed m |

▼a At first, we have investigated anisotropic electronic phase separation (EPS) of optimally doped La2/3Ca1/3MnO3 (LCMO) thin films under various degrees of anisotropic strain by static magnetotransport and dynamic relaxation measurements. Distinct |

▼a Substantial resistivity anisotropies along the two orthogonal in-plane directions in the EPS region were experimentally probed by static temperature and magnetic field dependent resistivity measurements. More strikingly, with increasing annealin |

▼a Furthermore, the EPS was found to exhibit glass-like behavior. The resistivity measured at fixed temperatures relaxes logarithmically over a long period of time. The relaxation behavior also shows a coherent enhancement with increasing annealing |

▼a In another project, we have investigated the superconductor-insulator quantum phase transitions tuned by disorder (d), magnetic impurity (MI) and magnetic field (B) in ultrathin Pb films by electrical transport measurement and single electron tu |

▼a There are two main theoretical models to explain SITs. The first one emphasizes that a transition from a superconducting state to a fermionic insulator without the existence of the superconducting order parameter, the formation of Cooper pairs i |

▼a Electron tunneling spectroscopy has been proposed to directly probe the existence and evolution of the superconductivity in these SITs. For B-tuned SITs, the existence of Cooper pairs is supposed to be detected even in the global insulating pha |

▼a Up to now, we have performed transport and tunneling measurements for d-tuned SITs in homogeneous Pb films in a 4He quench probe and the modified dilution refrigerator. The transport results are consistent with previous experiments from our gro |
