Long-living superfluidity of dark excitons in a strip of strained transition metal dichalcogenides double layer
Gabriel Pimenta Martins, Oleg L. Berman, Godfrey Gumbs +1
We have proposed the superfluidity of dipolar excitons in a strip of double-layer transition metal dichalcogenides (TMDCs) heterostructures. We have shown that strain causes a shif…
Superfluidity of dipolar excitons in a double layer of with a mass term
Oleg L. Berman, Godfrey Gumbs, Gabriel P. Martins +1
We predict Bose-Einstein condensation and superfluidity of dipolar excitons, formed by electron-hole pairs in spatially separated gapped hexagonal (GHAT3) layers. In the…
Quantum entanglement of multiple excitons in strained graphene
Gabriel P. Martins, Oleg Berman, Godfrey Gumbs +1
We studied the effects arising from a coherent source of photons on the entanglement between excitons in a strained graphene monolayer. The graphene layer was considered to be embe…
Polaritonic and Excitonic Time Crystals based on TMDC strips in an external periodic potential
Gabriel P. Martins, Oleg L. Berman, Godfrey Gumbs
We investigated the dynamics of Bose-Einstein condensates (BECs) under an external periodic potential. We consider two such systems, the first being made of exciton-polaritons in a…
Quantum entanglement between excitons in two-dimensional materials
Gabriel P. Martins, Oleg L. Berman, Godfrey Gumbs +1
The quantum entanglement between two excitons in two-dimensional materials, embedded in an optical microcavity, was investigated. The energy eigenstates of a Jaynes-Cummings like H…
Continuous Monitoring of Energy in Quantum Open Systems
Gabriel P. Martins, Nadja K. Bernardes, Marcelo F. Santos
We propose a method to continually monitor the energy of a quantum system. We show that by having some previous knowledge of the system's dynamics, but not all of it, one can use t…
