Exciton band structure in two-dimensional materials
Pierluigi Cudazzo, Lorenzo Sponza, Christine Giorgetti +3
Low-dimensional materials differ from their bulk counterpart in many respects. In particular, the screening of the Coulomb interaction is strongly reduced, which can have important…
Gravitino condensation, supersymmetry breaking and inflation
N. Houston
Motivated by dualistic considerations of the reality of quark condensation in quantum chromodynamics, and the connections of supergravity to the exotic physics of string and M-theo…
Polylogarithm identities, cluster algebras and the N=4 supersymmetric theory
C. Vergu
Scattering amplitudes in N = 4 super-Yang Mills theory can be computed to higher perturbative orders than in any other four-dimensional quantum field theory. The results are intere…
The Axiverse induced Dark Radiation Problem
Bobby Samir Acharya, Chakrit Pongkitivanichkul
The string/ theory Axiverse -- a plethora of very light Axion Like Particles (ALPs) with a vast range of masses -- is arguably a generic prediction of string/ theory. String/…
Modulation of diffusion rate of therapeutic peptide drugs using graphene oxide membranes
T. M. Puvirajesinghe, Z. L. Zhi, R. V. Craster +1
We investigate diffusion of a peptide drug through Graphene Oxide (GO) membranes that are modeled as a porous layered laminate constructed from aligned flakes of GO. Our experiment…
Supersymmetry, Cosmological Constant and Inflation: Towards a fundamental cosmic picture via "running vacuum"
Nick E. Mavromatos
On the occasion of a century from the proposal of General relativity by Einstein, I attempt to tackle some open issues in modern cosmology, via a toy but non-trivial model. Specifi…
