Current-induced cleaning of graphene [PDF]
, 2007 A simple yet highly reproducible method to suppress contamination of graphene at low temperature inside the cryostat is presented. The method consists of applying a current of several mA through the graphene device, which is here typically a few $\mu$m ...

STABILITY OF Z-STRINGS IN STRONG MAGNETIC FIELDS [PDF]
, 1995 We show that the Z-strings of the standard electroweak theory can be stabilized by strong external magnetic fields, provided that $\beta^{1/2} \equiv M_H/M_Z\leq 1$, where $M_H$ and $M_Z$ are the Higgs and Z masses.

Physicalism or Anti-physicalism: A Disjunctive Account
Erkenntnis, 2022 AbstractIn this paper, we make a case for the disjunctive view of phenomenal consciousness: consciousness is essentially disjunctive in being either physical or non-physical in the sense that it has both physical and non-physical possible instances.

Sodium Atoms in the Lunar Exotail: Observed Velocity and Spatial Distributions [PDF]
, 2011 The lunar sodium tail extends long distances due to radiation pressure on sodium atoms in the lunar exosphere. Our earlier observations measured the average radial velocity of sodium atoms moving down the lunar tail beyond Earth (i.e., near the anti ...

Measuring irreversible dynamics of a quantum harmonic oscillator [PDF]
, 2001 We show that the unitary evolution of a harmonic oscillator coupled to a two-level system can be undone by a suitable manipulation of the two-level system -- more specifically: by a quasi-instantaneous phase change.

EDULEARN Proceedings, 2019 Halfway between the experiment and the focus group, between the quiz and a game, we have experienced a new format to \"focus\" on sustainability and the fundamental laws of thermodynamics and its principles. Concepts as reversibility, efficiency and entropy, are then \"visualized\" by the participants, showing the relations with the economic value ...
