2. Holographic Complexity of Rotation

Abdulrahim Al Balushi

12/06/2020, 13:00

Theoretical Physics / Physique théorique (DTP-DPT)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Complexity is a measure of the resources required to perform certain computations. Quantum complexity is an important concept with applications spanning quantum information, condensed matter systems, and quantum field theories. It is defined as the minimum number of fundamental gates in a circuit required to construct a given quantum state. Surprisingly, it was found also to be connected to...

44. Aberration in Gravito-Electromagnetism

Victor Massart

12/06/2020, 13:15

Theoretical Physics / Physique théorique (DTP-DPT)

Invited Speaker / Conférencier(ère) invité(e)

The dynamical effects of general relativity which go past Newtonian gravity,
especially the expectation that gravitational effects propagate with a finite velocity, have not been directly verified.
The formalism of gravitoelectromagnetism will be applied to compute the
first dynamical corrections to Newtonian gravity due to general relativity.
We consider a system with multiple sources...

45. From the odd-even staggering to the pairing gap in neutron matter

Mr Georgios Palkanoglou (University of Guelph)

12/06/2020, 13:30

Theoretical Physics / Physique théorique (DTP-DPT)

Invited Speaker / Conférencier(ère) invité(e)

The properties of neutron matter are integral to the correct description of neutron stars and the extraction of their observables as well as the description of neutron-rich nuclei. One key property of neutron matter is its superfluid behaviour in a range of densities relevant to the inner crust of neutron stars. This talk will be centred around the finite size effects in the pairing gap of a...

7. Detecting Gravitational Waves with Bose-Einstein Condensates

Matthew Robbins (University of Waterloo/Perimeter Institute)

12/06/2020, 13:45

Theoretical Physics / Physique théorique (DTP-DPT)

Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

With the recent direct observation of gravitational waves, a new avenue of observing the Universe has become available. As a result, much effort is being devoted to the design of new detectors sensitive to different gravitational wave sources. One unique proposal is to detect gravitational waves using a Bose-Einstein Condensate (BEC). In this talk, I will show that transient gravitational wave...

3. Relativistic Causality and Vacuum Entanglement Harvesting with a Zero Mode

Erickson Tjoa (University of Waterloo)

12/06/2020, 14:00

Theoretical Physics / Physique théorique (DTP-DPT)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

We analyse how zero modes of a quantum field, whenever they arise, have significant impact on the phenomenology of light-matter interactions. Since a zero mode has no physical ground state, several studies in the literature opt to ignore the zero mode and argue that it has negligible impact on the physics. We show that (1) ignoring such modes directly leads to causality violation, in the sense...
