Oct 6, 2013 · Here, we use time- and angle-resolved photoemission spectroscopy with femtosecond extreme-ultraviolet pulses to directly probe the non-equilibrium response of Dirac electrons near the K-point of...
Edt, the Dirac electrons are accelerated and decelerated according to the interaction Hamiltonian H= 1 2m (p 2qA) . Scattering events with other electrons or with the lattice cause rapid thermalization into a hot carrier distribution. A set of experimental snapshots of the Dirac cone is plotted in Fig. 2b for di erent

Paul Dirac successfully incorpo-rated special theory of relativity into quantum me-chanics for the first time. This was accomplished through his ingenious use of matrices that allowed the equations of motion to maintain the necessary first order time derivative feature necessary for posi-tive probability density. The ensuing Dirac equation

Here, we use time- and angle-resolved photoemission spectroscopy with femtosecond extreme-ultraviolet pulses to directly probe the non-equilibrium response of Dirac electrons near the K-point of the Brillouin zone.
Paul Dirac and Stephen Hawking at the Institute for Advanced Study
Institute Instances is a collection of 1–2 minute video snapshots of scholars, administrators, and visitors to the Institute for Advanced Study answering a question (or two) about their work at IAS.
In 2002 physicists around the world celebrated the centenary of the birth of Paul Dirac, OM, FRS, Nobel Laureate, who was one of the greatest physicists of the 20th century. He made towering contributions to the formulation of quantum mechanics and he was one of the principal creators of quantum field theory.
