In recent years, quantum fluids of light in nonlinear optical systems have attracted a considerable interest [1]. [mehr]

Spectroscopy with terahertz (THz) fields is rapidly developing into a highprecision instrument that is able to characterize and steer quantum processes in semiconductors. [mehr]

I will discuss several cases where far out of equilibrium dynamics of many-body systems gives rise to emergent quasistationary states, that can be loosely termed as prethermalized. [mehr]

We examine the response of a system localized by disorder to a time dependent local perturbation which varies smoothly with a characteristic timescale τ. [mehr]

Black holes are one of the most mysterious concepts in physics and carry with them a large number of unsolved problems and counterintuitive results, none of which are more troubling than the information paradox. [mehr]

We study impure mesoscopic one-dimensional ensembles with majority particles either non-interacting fermions or bosons. [mehr]

Traditional thermodynamics deals with macroscopic systems in thermal equilibrium, where one only has control over a few macroscopic variables (volume, temperature, etc). [mehr]

We give restrictions on locality-preserving unitary automorphisms U, which are protected gates, for 2-dimensional topologically ordered systems. [mehr]

The strong interactions of elementary particles are described theoretically in the framework of Quantum Chromodynamics (QCD). [mehr]

Nitrogen-vacancy (NV) center is one of the most promising systems for quantum information processing. [mehr]

The main focus of this edition of the Symposia on Topological Quantum Information will be the realization of topological phases of matter in cold-atom setups. The Symposium will be mainly aimed to PhD students and postdocs working in this field. [mehr]

Interactions between light and matter lie at the heart of optical communication and information technology. [mehr]

In recent years, systems of ultracold atoms in optical lattices have opened new opportunities for exploring time-dependent many-body dynamics. [mehr]

Several types of quantum-dot spin valves were recently realized. For such systems, we have analyzed the efficient transfer of angular momentum into the nuclear bath and the detection of nuclear-spin coherence through transport signatures. [mehr]

A 3-mode optomechanical system (e.g., with two electromagnetic fields coupled to a single mode of a mechanical resonator) is a key element of hybrid quantum systems. [mehr]

A new frontier of extreme light at Exawatt level is discussed. This frontier has approached to us much closer than we thought till only recently. [mehr]

“We propose to use Quantum Hall edge channels in order to generate long-range entanglement between spatially separated spin qubits. Since the entanglement is actively stabilized by purely dissipative dynamics, our scheme is inherently robust against noise and imperfections.” [mehr]

The active laser cavity can be considerably more sensitive than a passive one to minute perturbations. The difference in sensitivity between passive and active resonator sensors is akin to forensic dissection as compared to vivisection. [mehr]

Quantum correlations are strongly enhanced near quantum critical points, which opens attractive prospects for applications such as quantum-enhanced metrology. [mehr]

It was long considered a practical impossibility to extend the methods of laser cooling and trapping to diatomic molecules. [mehr]

The availability of waveform-controlled, intense, few cycle laser fields has radically expanded the ability of scientists to peer into the dynamics of atoms and solids on few-femtosecond or even attosecond time scales. This research in the field of attosecond science has hinted at the potential for new discoveries that may be unlocked by new developments in laser science to confine more and more energy into smaller and smaller packages to be precisely delieved to the systems under study.

If a polarization excess is injected in many-spin quantum system which is initially in a high-temperature equilibrium, then this “excitation” would spread all over as consequence of spin-spin interactions. [mehr]

Photonic entanglement is one of the most common methods to generate and study entangled states. Photon pairs can be entangled in different degrees freedom including polarisation, momentum or energy. [mehr]

The quantum cascade laser has demonstrated the ability to provide gain over a very broad wavelength range. [mehr]

Large spin systems can exhibit unconventional types of magnetic ordering different from the ferromagnetic or N\'eel-like antiferromagnetic order commonly found in spin 1/2 systems. [mehr]

The radius of the proton, generally assumed to be a well measured and understood  quantity has recently come under scrutiny due to highly precise, yet conflicting, experimental results. These new results have generated a host of interpretations, none of which are completely satisfactory. [mehr]
