CTQM Theory Colloquium

Abstrace:  Back in 1973, Sidney Coleman and Nobel Prize winner David Gross proved that only non-abelian gauge theories can have asymptotic freedom.

Abstract: Current through a resistor exhibits temperature-dependent white noise fluctuations called Johnson-Nyquist noise. For a 2D electron system, measuring the magnitude of these fluctuations provides a direct measurement of the electron temperature, and thereby enables a novel method for inferring specific heat and thermal conductivity. Here I present three general theoretical results about Johnson noise thermometry in both the ohmic and hydrodynamic limits.

Abstract: Over the past 15 years, there has been a remarkable amount of progress understanding ga

Abstract: The ability to prepare ground states of many-body Hamiltonians on quantum devices is of central importance for a variety of tasks and applications in quantum computation and quantum simulation.

Abstract:  In recent years it has been shown that strongly coupled many body systems become analytically tractable in the regime of large quantum numbers, such as large spin or large charge. We will review these developments and present applications to the theory of critical exponents.
