Superfluid density in the underdoped YBa_2Cu_3O_{7-x}: Evidence for d-density wave order of pseudogap
M. R. Trunin, Yu. A. Nefyodov, A. F. Shevchun
The investigation of the penetration depth λ_{ab}(T,p) in YBa_2Cu_3O_{7-x} crystals allowed to observe the following features of the superfluid density n_s(T,p)\propto λ_{ab}^{-2}(…
Comment on "Interaction Effects in Conductivity of Si Inversion Layers at Intermediate Temperatures"
A. A. Shashkin, V. T. Dolgopolov, S. V. Kravchenko
We show that the comparison between theory and experiment, performed by Pudalov et al. in PRL 91, 126403 (2003), is not valid.
Remote-doping scattering and the local field corrections in the 2D electron system in a modulation-doped Si/SiGe quantum well
V. T. Dolgopolov, E. V. Deviatov, A. A. Shashkin +4
The small, about 30% magnetoresistance at the onset of full spin polarization in the 2D electron system in a modulation-doped Si/SiGe quantum well gives evidence that it is the rem…
Sharply increasing effective mass: a precursor of the spontaneous spin polarization in a dilute two-dimensional electron system
A. A. Shashkin, S. V. Kravchenko, V. T. Dolgopolov +1
We have measured the effective mass, m, and Lande g-factor in very dilute two-dimensional electron systems in silicon. Two independent methods have been used: (i) measurements of t…
Direct measurements of the spin and the cyclotron gaps in a 2D electron system in silicon
V. S. Khrapai, A. A. Shashkin, V. T. Dolgopolov
Using magnetocapacitance data in tilted magnetic fields, we directly determine the chemical potential jump in a strongly correlated two-dimensional electron system in silicon when…
Spin-independent origin of the strongly enhanced effective mass in a dilute 2D electron system
A. A. Shashkin, Maryam Rahimi, S. Anissimova +3
We have accurately measured the effective mass in a dilute two-dimensional electron system in silicon by analyzing temperature dependence of the Shubnikov-de Haas oscillations in t…
