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 temperature or magnetic field, going first from a vortex solid to a hexatic vortex fluid and then from a hexatic vortex fluid to an isotropic vortex liquid. In this paper, we show that the resistance in the vortex fluid states is extremely sensitive to radio-frequency electromagnetic perturbation. In the… 
An inertial model of vortices to explain the extreme sensitivity of hexatic vortex fluid to low frequency ac excitation
Abstract Recently, it has been demonstrated that the Hexatic vortex fluid realized in 2-dimensional vortex state of a very weakly pinned amorphous MoGe thin film is extremely sensitive to external ac

Quantum Criticality inside the Anomalous Metallic State of a Disordered Superconducting Thin Film.
Using Nernst effect measurements, superconducting fluctuations are uncovered in the vicinity of the field-induced metallic state in an amorphous Mo_{x}Ge_{1-x} thin film, indicating that the metallic state results from quantum vortex liquid (QVL) with phase fluctuations due to quantum fluctuations.
Experimental test of strong pinning and creep in current-voltage characteristics of type-II superconductors

Evidence of zero-point fluctuation of vortices in a very weakly pinned a -MoGe thin film
In a Type II superconductor, the vortex core behaves like a normal metal. Consequently, the single-particle density of states in the vortex core of a conventional Type II superconductor remains

Collective flux pinning in hexatic vortex fluid in a-MoGe thin film.
The results demonstrate that a "peak effect" can arise at the order-disorder transition of the vortex lattice even when both the ordered and disordered states are vortex fluids, such as the boundary between a hexatic vortex fluid and an isotropic vortex liquid.

Freezing of the vortex liquid in high-Tc superconductors: A density-functional approach.
The structure of the unpinned vortex fluid in layered oxide high-temperature superconductors is investigated numerically using appropriate classical liquid-state theory, and this transition boundary is found to have a shape and location similar to that observed in strongly anisotropic materials, e.g., Bi-Sr-Ca-Cu-O.
