چکیده

We use electromigration (EM) to tune the oxygen content of YBa$_2$Cu$_3$O$_{7-\delta}$ (YBCO) nanowi\-res. During EM, dopant atoms in nanowire are moved under combined effect electrostatic force and Joule heating. The EM current can be tuned either deplete or replenish nanowires with oxygen, allowing fine tuning its hole doping level. Electrical transport measurements Kelvin probe microscopy corroborate good homogeneity level along electromigrated nanowires. Thus, provides an effective method study properties YBCO a wide range at nanoscale one same device.

Mapping the QCD Phase Diagram

The QCD vacuum in which we live, which has the familiar hadrons as its excitations, is but one phase of QCD, and far from the simplest one at that. One way to better understand this phase and the nonperturbative dynamics of QCD more generally is to study other phases and the transitions between phases. We are engaged in a voyage of exploration, mapping the QCD phase diagram as a function of tem...

Mapping the phase diagram of strongly interacting matter

The properties of strongly interacting matter at finite temperature, T 6= 0, and baryon density, nB 6= 0, has been studied extensively in recent years. The Phase Diagram (PD) is being explored experimentally in heavy-ion collisions and examined theoretically in models as well as in first-principle calculations of QCD. In the non-perturbative regime of QCD, Lattice Gauge Theory (LGT) provides a ...

Mapping the topological phase diagram of multiband semiconductors with supercurrents.

We show that Josephson junctions made of multiband semiconductors with strong spin-orbit coupling carry a critical supercurrent Ic that contains information about the nontrivial topology of the system. In particular, we find that the emergence and annihilation of Majorana bound states in the junction is reflected in strong even-odd effects in Ic at small junction transparency. This effect allow...
