Observation of half-integer thermal Hall conductance

Autor: Banerjee, Mitali, Heiblum, Moty, Umansky, Vladimir, Feldman, Dima E., Oreg, Yuval, Stern, Ady

Topological states of matter are characterized by topological invariant, which are physical quantities whose values are quantized and do not depend on details of the measured system. Of these, the easiest to probe in experiments is the electrical Hal

Observed Quantization of Anyonic Heat Flow

Autor: Banerjee, Mitali, Heiblum, Moty, Rosenblatt, Amir, Oreg, Yuval, Feldman, Dima E., Stern, Ady, Umansky, Vladimir

The quantum of heat conductance of ballistic one-dimensional (1D) channels, being gQ=k0T with k0=pi^2*2kB^2/3h (T - temperature, kB - Boltzmann's constant, h - Planck's constant), is an important fundamental constant. While the quantization of the el

First-order disorder-driven transition and inverse melting of the vortex lattice

Autor: Avraham, Nurit, Khaykovich, Boris, Myasoedov, Yuri, Rappaport, Michael, Shtrikman, Hadas, Feldman, Dima E., Zeldov, Eli, Tamegai, Tsuyoshi, Kes, Peter H., Li, Ming, Konczykowski, Marcin, van der Beek, Kees

Vortex matter phase transitions in the high-temperature superconductor Bi2Sr2CaCu2O8 were studied using local magnetization measurements combined with a vortex 'shaking' technique. The measurements revealed thermodynamic evidence of a first-order tra

Comment on 'Quantum Pump for Spin and Charge Transport in a Luttinger Liquid'

Autor: Feldman, Dima E., Gefen, Yuval

This is a Comment to the paper by Sharma and Chamon in Phys. Rev. Lett. 87 (2001) 096401 (cond-mat/0011025). We show that the prediction of the universal charge pumped per cycle in the fast limit for attractive electron-electron interaction is invali

Report

Inverse melting of the vortex lattice

Autor: Avraham, Nurit, Khaykovich, Boris, Myasoedov, Yuri, Rappaport, Michael, Shtrikman, Hadas, Feldman, Dima E., Tamegai, Tsuyoshi, Kes, Peter H., Li, Ming, Konczykowski, Marcin, van der Beek, Kees, Zeldov, Eli

Publikováno v: Nature (London) 411, 451 (2001).

Inverse melting, in which a crystal reversibly transforms into a liquid or amorphous phase upon decreasing the temperature, is considered to be very rare in nature. The search for such an unusual equilibrium phenomenon is often hampered by the format
