Quantum cavity electro-mechanics with ultra-high impedance microwave circuits
vCal iCal
Speaker: Johannes Fink
When: Mar. 23. 2015 17:00
Where: Erwin-Schödinger-Saal, IQOQI

Superconducting circuits are at the focus of quantum engineering research because of their potential for scalable quantum information processing and simulation. One disadvantage of circuit QED systems ...

Seminar

Matter-wave interferometry close to the surface of an atom-chip
vCal iCal
Speaker: Ron Folman
When: Mar. 05. 2015 09:00
Where: Erwin Schrödinger Saal

Matter-wave interferometry on atom-chips has been around for a decade. Several groups around the world are now operating such devices based on different methods for splitting such as light, RF, and MW ...

Seminar

Commensurability and friction in an ion-cavity system
vCal iCal
Speaker: Thomas Fogarty
When: Mar. 03. 2015 15:00
Where: IQOQI lecture hall

I describe the process of self-organisation of ions in an optical cavity due to the interplay between the Coulomb forces of the ions and the optical forces from the cavity. This can be described in th ...

Talk

How do you measure a Fermionic Quantum Field as a Theorist? -- Unruh-DeWitt-type Particle Detector Models for Scalar and Spinor Fields
vCal iCal
Speaker: Daniel Hümmer
When: Feb. 03. 2015 15:00
Where: Erwin Schrödinger Saal.

In theoretical physics, there is multitude of different mathematical methods how to explore the properties of a quantum field. Among these, particle detector models have become a pop ...

What does it mean for half of an empty box to be full?
vCal iCal
Speaker: Eric Brown
When: Feb. 02. 2015 15:00
Where: Erwin Schrödinger Saal.

It is well known that the vacuum state of a quantum field is spatially entangled. This is true both in free and confined spaces, for example in an optical cavity. The obvious consequence of this, howe ...

Seminar

Magnetism with spinor Bose-Einstein condensates with antiferromangetic interactions
vCal iCal
Speaker:
When: Jan. 29. 2015 09:00
Where: Erwin Schrödinger Saal

We experimentally study the magnetic properties of spin-1 Bose-Einstein condensate of Sodium at equilibrium. In this system the atoms can occupy any of the three Zeeman states. We measure the spin sta ...

Talk

Back-action driven transport of Bloch oscillating atoms in ring cavities
vCal iCal
Speaker: Prasanna Venkatesh Balasubramanian
When: Jan. 27. 2015 14:00
Where: Erwin Schrödinger Saal.

Transport under uniform bias in normal metallic systems requires dephasing of Bloch oscillations due to presence of impurities. In contrast, for atoms in optical lattices (with an external applied un ...

Seminar

How to manipulate neuronal function in a mouse brain, without wires
vCal iCal
Speaker: Hans Bachor
When: Jan. 22. 2015 15:00
Where: IQOQI lecture hall

Light is now an indispensable tool among neuroscientists, particularly for the visualisation and characterisation of cells and proteins and for functional imaging. Coherent laser technology with spect ...

Seminar

Outlook for the Quantum Computation of Quantum Chemistry
vCal iCal
Speaker: Ryan Babbush
When: Jan. 15. 2015 15:00
Where: Erwin Schrödinger Saal

The central problem of quantum chemistry is to solve for the energy of electrons interacting in the nuclear potential of a molecule. While widely believed to be classically intractable, quantum comput ...

Lecture

Gravitational quantum physics
vCal iCal
Speaker: Časlav Brukner
When: Jan. 09. 2015 10:00
Where: Erwin Schrödinger Saal

Quantum physics differs from classical physics in that no definite values can be attributed to observables independently of the measurement context. However, the notion of time and of causal order pre ...
