Dissipation in small systems: Landau-Zener approach
(Amer Physical Soc., 2016-06-13)
We establish a stochastic thermodynamics for a Fermionic level driven by a time-dependent force and interactingwith initially thermalized levels playing the role of a reservoir. The driving induces consecutive avoided ...
Collapse of rho (xx) Ringlike Structures in 2DEGs Under Tilted Magnetic Fields
(SPRINGER, 2010)
In the quantum Hall regime, the longitudinal resistivity rho (xx) plotted as a density-magnetic-field (n (2D) -B) diagram displays ringlike structures due to the crossings of two sets of spin split Landau levels from ...
Dissipation in small systems: Landau-Zener approach
(2016)
We establish a stochastic thermodynamics for a Fermionic level driven by a time-dependent force and interactingwith initially thermalized levels playing the role of a reservoir. The driving induces consecutive avoided ...
Carbon-13 dynamic nuclear polarization in diamond via a microwave-free integrated cross effect
(National Academy of Sciences, 2019-09)
Color-center–hosting semiconductors are emerging as promising source materials for low-field dynamic nuclear polarization (DNP) at or near room temperature, but hyperfine broadening, susceptibility to magnetic field ...
Three-dimensional and two-dimensional high field vortex fluctuations in deoxygenated YBa2Cu3O7-x depending on the vicinity of T-c(H)
(Elsevier Science BvAmsterdamHolanda, 2006)
Weak localization and conductance fluctuations-like effects in Qubits driven by biharmonic signals
(IOP Publishing, 2014-12)
We investigate the effect of broken time reversal symmetry in flux qubits driven by a biharmonic magnetic flux signal with a phase lag. In the regime of large relaxation times, we explicitly compute the transition rate ...
Magnetic corrections to the pion electromagnetic form factor
(2020)
In this work, we investigate the effect of a magnetic field background to the pion electromagnetic form factor. We face this problem through the Finite Energy Sum Rule (FESR)
program, where a suitable current correlation ...
Efectos de la interacción electrón-electrón y campos magnéticos en gases bidimensionales de electrones
(2019-03-26)
En este trabajo hemos estudiado los efectos de la interacción electrón-electrón y campos magnéticos en gases cuasi-bidimensionales de electrones (q2DEGs). Para estos sistemas, con un campo magnético aplicado en la dirección ...
