Magnetic field induced transition from a vortex liquid to Bose metal in ultrathin a-MoGe thin film

  author={Surajit Dutta and John Jesudasan and Pratap Raychaudhuri},
We identify a magnetic field induced transition from a vortex liquid to Bose metal in a 2-dimensional amorphous superconductor, a-MoGe, using a combination of magnetotransport and scanning tunnelling spectroscopy (STS). Below the superconducting transition, Tc ~ 1.36 K, the magnetoresistance isotherms cross at a nearly temperature independent magnetic field, Hc ~ 36 kOe. Above this field, the temperature coefficient of resistance is weakly negative, but the resistance remains finite as T  0…

Phase diagram of the strongly disordered s-wave superconductor NbN close to the metal-insulator transition
We present a phase diagram as a function of disorder in three-dimensional NbN thin films, as the system enters the critical disorder for the destruction of the superconducting state. The
Enhancement of the finite-frequency superfluid response in the pseudogap regime of strongly disordered superconducting films
It is shown that the dynamic response above Tc, obtained from the complex ac conductivity, is highly modified in the pseudogap regime of strongly disordered NbN films, suggesting a scenario of thermal phase fluctuations between superconducting domains in a strongly dis ordered s-wave superconductor.
Intermediate bosonic metallic state in the superconductor-insulator transition
How quantum phase coherence evolves across superconductor–metal–insulator transitions through magnetoconductance quantum oscillations in nanopatterned high-temperature superconducting films is studied and it is suggested that the anomalous metallic state is bosonic and that the saturation ofphase coherence plays a prominent role in its formation.
Superconductivity on the localization threshold and magnetic-field-tuned superconductor-insulator transition in TiN films
Temperature-and magnetic-field-dependent measurements of the resistance of ultrathin superconducting TiN films are presented. The analysis of the temperature dependence of the zero-field resistance
Magnetic-field-tuned superconductor-insulator transition in two-dimensional films.
A magnetic field is used to tune through a new superconducting-insulating transition of amorphous-composite indium oxide films at various stages of disorder and scaling behavior of the resistance over a wide range of temperatures and magnetic fields is found.
Collective energy gap of preformed Cooper pairs in disordered superconductors
In most superconductors, the transition to the superconducting state is driven by the binding of electrons into Cooper pairs1. The condensation of these pairs into a single, phase-coherent, quantum
Pseudogap in a thin film of a conventional superconductor.
It is shown that a pseudogap exists in a conventional superconductor, ultrathin titanium nitride films, over a wide range of temperatures above T(c), and is induced by superconducting fluctuations and favoured by two-dimensionality and by the proximity to the transition to the insulating state.
Bose metal: Gauge-field fluctuations and scaling for field-tuned quantum phase transitions
We extend our previous discussion of the Bose metal to the field-tuned case. We point out that the recent observation of the metallic state as an intermediate phase between the superconductor and the
Theory of quantum metal to superconductor transitions in highly conducting systems
We derive the theory of the quantum (zero-temperature) superconductor to metal transition in disordered materials when the resistance of the normal metal near criticality is small compared to the
Extreme sensitivity of the vortex state in a -MoGe films to radio-frequency electromagnetic perturbation
Recently, detailed real space imaging using scanning tunneling spectroscopy of the vortex lattice in a weakly pinned a-MoGe thin film revealed that the vortex lattice melts in two steps with
