Stoner Magnetism in an Inversion Layer
D. I. Golosov
Motivated by recent experimental work on magnetic properties of Si-MOSFETs, we report a calculation of magnetisation and susceptibility of electrons in an inversion layer, taking i…
Korshunov instantons out of equilibrium
M. Titov, D. B. Gutman
Zero-dimensional dissipative action possesses non-trivial minima known as Korshunov instantons. They have been known so far only for imaginary time representation that is limited t…
Localized magnetic moments in a Dirac semimetal as a spin model with long--range interactions
Eugene Kogan, Moshe Kaveh
We connect between the problem of thermodynamics of localized magnetic moments in a Dirac semimetal, the interaction with relativistic electrons leading to the effective ferromagne…
Hopping magnetoresistance in ion irradiated monolayer graphene
I. Shlimak, E. Zion, A. V. Butenko +8
Magnetoresistance (MR) of ion irradiated monolayer graphene samples with variable-range hopping (VRH) mechanism of conductivity was measured at temperatures down to K in…
Fractional Coulomb blockade in a coupling controlled metallic quantum dot
O. Bitton, A. Frydman, R. Berkovits +1
We use a novel technique to experimentally explore transport properties through a single metallic nanoparticle with variable coupling to electric leads. For strong dot-lead couplin…
Entanglement properties and quantum phases for a fermionic disordered one dimensional wire with attractive interactions
Richard Berkovits
A fermionic disordered one dimensional wire in the presence of attractive interactions is known to have two distinct phases: A localized and a superconducting one depending on the…
