Fermi velocity reduction in graphene due to enhanced vacuum fluctuations
(IOP Publishing, 2021-09)
It is well known that the confinement of matter inside a microcavity can significantly enhance the light-matter interactions. As a result the vacuum fluctuations, induced by virtual photons, can occur in a volume much lower ...
Thomas-Fermi approximation in two p-type delta-doped quantum wells in GaAs and Si
(Revista Mexicana de Física, 2009)
Fermi surface reconstruction in underdoped cuprates: Origin of electron pockets
(American Physical Society, 2018-12-17)
A new phenomenological model is proposed to describe the evolution of the Fermi surface (FS) in a wide range of dopings. It reproduces the key features of the cuprates in the underdoped phase above the superconducting ...
q-thermostatistics and the analytical treatment of the ideal Fermi gas
(Elsevier Science, 2004-02)
We discuss relevant aspects of the exact q-thermostatistical treatment for an ideal Fermi system. The grand-canonical exact generalized partition function is given for arbitrary values of the nonextensivity index q, and ...
Non-Fermi liquids at finite temperature: Normal-state and infrared singularities
(American Physical Society, 2017-10-16)
We analyze quantum criticality at finite temperature for a class of non-Fermi liquids with massless bosons. Finite temperature gives rise to new infrared singularities that invalidate standard perturbative treatments. We ...
Decay of accelerated protons and the existence of the Fulling-Davies-Unruh effect
(2001-10-08)
A theoretic-oriented strategy was taken to address the weak decay of uniformly accelerated protons. The decay of uniformly accelerated p+'s was analyzed using standard quantum field theory (QFT). It was shown that the FDU ...
Density of States of a Nanoscale Semiconductor Interface as a Transduction Signal for Sensing Molecules
(2021-08-24)
Nanoscale inorganic semiconductors (with interfacial thickness <10 nm) have superior stability compared to soft organic compounds and are important for the development of enhanced reagentless sensing devices. As a proof ...
Absence of Cooper-type bound states in three- and few-electron systems
(1998-12-01)
It is shown that the appearance of a fixed-point singularity in the kernel of the two-electron Cooper problem is responsible for the formation of the Cooper pair for an arbitrarily weak attractive interaction between two ...
