In this work, we use two gas mass fraction samples of galaxy clusters obtained from their X-ray surface brightness observations jointly with recent $H(z)$ data in a flat $\Lambda$CDM framework to impose limits on cosmic opacity. It is assumed that th

In this work we investigate the two dimensional electron gas on surfaces showing Gaussian bumps. Due to confinement on two dimensional curved space, a geometry-induced potential appears. For surfaces showing single bumps, the geometrical potential gi
