Spinning top-ology
When
-
Abstract: Geometry, topology and broken symmetry play a powerful role in determining the physics of materials.
Physics Department Colloquium
A diatomic molecule in a superfluid helium droplet: Is the anomalous Zeeman splitting a signature of a microscopic Einstein - de Hass effect
When
-
Abstract:
The first beam of helium droplets was reported in the 1961 paper Strahlen aus kondensiertem Helium im Hochvakuum by Von E. W. Becker and co-workers [1].
From quantum optics to bits and pieces
When
-
Abstract: In this talk, I shall review the arguments applied by Roy Glauber in the early 1960’s to characterize temporal fluctuations in photo-detection signals. S
Fast jet stream winds get faster under climate change
When
-
Abstract: Earth's upper-level jet streams influence the speed and direction of travel of weather systems and commercial aircraft.
Programmable control of indistinguishable particles: from sampling to clocks to qubits
When
-
Quantum information science seeks to exploit the collective behavior of a large quantum system to enable tasks that are impossible (or less possible!) with classical resources alone.
Epidemics, Erdos numbers, and the Internet: The Physics of Networks
When
-
Abstract: There are networks in every part of our lives: the Internet, the road network, networks of friendship or acquaintance, biochemical networks, ecological networks, the power grid, and many others.
Lise Meitner, Her Escape from Germany and the Discovery of Fission
When
-
Abstract: Lise Meitner was one of the pioneers of nuclear physics and co-discoverer, with Otto Hahn and Fritz Strassmann, of nuclear fission. Albert Einstein once called her, "the most significant woman scientist of the 20th century".
Stacking van der Waals atomic layers: quest for new quantum materials
When
-
Abstract: Modern electronics rely heavily on technology that confines electrons in the interface layers of semiconductors. In recent years, scientists have discovered that they can isolate various atomically thin van der Waals (vdW) layered materials.
How Much Information Is In A Quantum State?
When
-
Abstract: To describe an entangled state of n particles, we formally need an amount of classical information that grows exponentially with n. But given that almost all the information disappears on measurement, in what sense was it "really there"?
