“The career structure and funding of the universities [...] currently strongly discourages
academics and faculties from putting any investment into teaching–there are no career or …

Projective measurements in random quantum circuits lead to a rich breadth of entanglement
phases and extend the realm of nonunitary quantum dynamics. Here, we explore the …

Critical phenomena arise in a wide variety of physical systems. Classi cal examples are the
liquid-vapour critical point or the paramagnetic ferromagnetic transition. Further examples …

We show that a strongly interacting chain of Majorana zero modes exhibits a
supersymmetric quantum critical point corresponding to the c= 7 1 0 tricritical Ising model …

We demonstrate that in a triangular configuration of an optical lattice of two atomic species a
variety of novel spin-1/2 Hamiltonians can be generated. They include effective three-spin …

The Hubbard and spinless fermion chains are paradigms of strongly correlated systems,
very well understood using the Bethe ansatz, density matrix renormalization group (DMRG) …

We study a Hamiltonian system describing a three-spin-1/2 clusterlike interaction competing
with an Ising-like antiferromagnetic interaction. We compute free energy, spin-correlation …

Quantum phase transitions occur at zero temperature, when the ground state of a
Hamiltonian undergoes a qualitative change as a function of a control parameter. We …

The investigation of quantum mechanical systems mostly concentrates on single elementary
particles. If we combine such particles into a composite quantum system, the number of …

We study a one-dimensional spin-1/2 model with three-spin interactions and a transverse
magnetic field h. The model is known to have a Z 2× Z 2 symmetry and a duality between h …
