A Cavity-Microscope for Quantum Simulations with Locally-Controllable All-to-All Interactions
This thesis presents the development, construction, and benchmark of an experimental platform that combines cold fermionic 6Li atoms with locally controllable light-matter interactions. To enable local control, a new device, the cavity-microscope, was crea ...
EPFL2024Holography and localization of information in quantum gravity
Kyriakos Papadodimas, Alexandre Mathieu Frédéric Belin
Within the AdS/CFT correspondence, we identify a class of CFT operators which represent diff-invariant and approximately local observables in the gravitational dual. Provided that the bulk state breaks all asymptotic symmetries, we show that these operator ...
Springer2024Ultra-high quantum coherent and scalable superconducting circuit optomechanics, from topological lattices to quantum storage
Mechanical oscillators can exhibit modes with ultra-low energy dissipation and compact form factors due to the slow velocity of acoustic waves, and are already used in applications ranging from timing to wireless filters. Over the past decade, novel ways i ...
EPFL2024A squeezed mechanical oscillator with millisecond quantum decoherence
Tobias Kippenberg, Amir Youssefi, Mahdi Chegnizadeh, Shingo Kono
An enduring challenge in constructing mechanical-oscillator-based hybrid quantum systems is to ensure engineered coupling to an auxiliary degree of freedom and maintain good mechanical isolation from the environment, that is, low quantum decoherence, consi ...
NATURE PORTFOLIO2023Matter matters in Einstein-Cartan gravity
Andrey Shkerin, Georgios Karananas, Sebastian Zell
We study scalar, fermionic and gauge fields coupled nonminimally to gravity in the Einstein-Cartan formulation. We construct a wide class of models with nondynamical torsion whose gravitational spectra comprise only themassless graviton. Eliminating nonpro ...
AMER PHYSICAL SOC2021Einstein-Cartan Portal to Dark Matter
Andrey Shkerin, Inar Timiryasov, Sebastian Zell
It is well known since the works of Utiyama and Kibble that the gravitational force can be obtained by gauging the Poincare group, which puts gravity on the same footing as the standard model fields. The resulting theory-Einstein-Cartan gravity-inevitably ...
AMER PHYSICAL SOC2021Nonperturbative Mellin Amplitudes
Conformal field theory lies at the heart of two central topics in theoretical high energy physics: the study of quantum gravity and the mapping of quantum field theories through the renormalization group. In this thesis we explore a technique to study conf ...
