The renormalization group plays an essential role in many areas of physics, both
conceptually and as a practical tool to determine the long-distance low-energy properties of …

We review the recent developments and the current status in the field of quantum-gas cavity
QED. Since the first experimental demonstration of atomic self-ordering in a system …

The concept of a supersolid state combines the crystallization of a many-body system with
dissipationless flow of the atoms from which it is built. This quantum phase requires the …

Twisted bilayer graphene displays insulating and superconducting phases caused by
exceptional flattening of its lowest energy bands. Superconductivity with highest T c appears …

In the asymptotic safety paradigm, a quantum field theory reaches a regime with quantum
scale invariance in the ultraviolet, which is described by an interacting fixed point of the …

We zoom in on the microscopic dynamics for fermions and quantum gravity within the
asymptotic-safety paradigm. A key finding of our study is the unavoidable presence of a …

We report heat capacity measurements of SrCu 2 (BO 3) 2 under high pressure along with
simulations of relevant quantum spin models and map out the (P, T) phase diagram of the …

In a quantum phase transition, the ground state and low-temperature properties of a system
change drastically as some parameter controlling zero-point quantum fluctuations is tuned to …

Artificial spin-ice systems are magnetic metamaterials consisting of nanomagnet arrays that
can be designed to study exotic magnetic states not found in natural materials. Typically …

A bstract We discover a weak-gravity bound in scalar-gravity systems in the asymptotic-
safety paradigm. The weak-gravity bound arises in these systems under the approximations …
