Abstract: It is well known that conserved quantities cannot have anomalous dimensions. However, a recent proposal for the ubiquitous strange metal phase in the cuprates argues just the opposite. Namely, all of the properties of such `strange metals' can be understood if the current has an anomalous dimension.

## Condensed Matter Seminar

### Condensed Matter Seminar | Philip Phillips, UIUC | "Anomalous Dimensions for Conserved Currents and Extra Dimensions in the Strange Metal?" | Jadwin PCTS Seminar Room 407

### Special Condensed Matter Seminar | Rudolf Grimm, UIBK | "Impurities in an ultracold Fermi sea: Quasiparticles, phase separation and beyond" | Jadwin 111

Abstract: Impurity physics has emerged as a new branch of research in the field of atomic quantum gases. A central feature is the wide tunability of interactions between the impurities and the surrounding medium. By using magnetically controlled Feshbach resonances, regimes of strong interactions can be reached which reveal intriguing many-...

### Condensed Matter Seminar | Benjamin Lev, Stanford | "Exploring quantum thermalization with a magnetic quantum Newton’s cradle" | Jadwin 303

Abstract: Isolated quantum many-body systems with integrable dynamics generically do not thermalize starting from generic initial states when taken far from equilibrium. As one perturbs such systems away from the integrable point, thermalization sets in, but the nature of the crossover from integrable to thermalizing behavior is an unresolved...

### Special CM Seminar | Ruben Verresen, TUM & Max Planck |"The Topology and Quantum Criticality in 1+1D" | PCTS Seminar Room 407

Abstract: Ground states of gapped Hamiltonians can form 'symmetry-protected topological phases', characterized by zero-energy edge modes. We explore the quantum critical points between such topological phases in one spatial dimension.

### Condensed Matter Seminar | Karol Gregor, Google DeepMind, London | "Machine Learning: Methods and recent successes." | PCTS, Seminar Room 407

Abstract: Artificial Intelligence/Machine learning has seen large growth and a number of successes over the past few years. In this talk I will describe some of the core ideas and algorithms along with corresponding results. We will start by thinking about intelligence in general.

Abstract:

### Condensed Matter VIDEO Seminar, Antoine Browaeys, Inst. Optique, "Many-body physics with arrays of individual Rydberg atoms" PCTS Seminar Room 407

Abstract: This talk will present our on-going effort to control the dipole-dipole interaction between cold Rydberg atoms in order to implement spin Hamiltonians that may be useful for quantum simulation of condensed matter problems.

### Condensed Matter Seminar, Jeremy Levy, U. Pittsburgh, "Correlated Nanoelectronics" PCTS Seminar Room 407

Abstract: The study of strongly correlated electronic systems and the development of quantum transport in nanoelectronic devices have followed distinct, mostly non-overlapping paths. Electronic correlations of complex materials lead to emergent properties such as superconductivity, magnetism, and Mott insulator phases.

### Condensed Matter Seminar, Chong Wang, Harvard, "A Web of Dualities in Condensed Matter Physics: from Quantum Hall Effect to Exotic Quantum Criticality," PCTS Seminar Room 407

Abstract: Two seemingly different quantum field theories may secretly describe the same underlying physics — a phenomenon known as “duality". I will review some recent developments in field theory dualities in (2+1) dimensions and some of their applications in condensed matter physics, in particular in quantum Hall effect and quantum phase...

### Condensed Matter Seminar, Alessandra Lanzara, Berkeley, "From Mott Physics to Topology " PCTS Seminar Room 407

Two types of interactions commonly drive new emergent phenomena beyond textbook band theory in solids: electron correlation and spin orbit coupling.

### Condensed Matter Seminar, Sean Hartnoll, "Bounds on transport", PCTS Seminar Room 407

Abstract: There is a long history to the idea that transport may be subject to fundamental constraints. I will argue that variants of these ideas offer promising ways to think about non-quasiparticle transport.

### Special CM Seminar, Malin Nilsson, Lund U. "Charge and spin transport in parallel quantum dots in nanowires"

We use quantum dots (QDs) formed by crystal-phase tuning during epitaxial growth of InAs nanowires as a starting point to realize and electrically characterize two different types of parallel-coupled quantum dots; electron-hole QDs and electron-electron QDs.

### Special CM Seminar, Timon Hilker, Max Planck, "Spin resolved microscopy of doped Hubbard chains"

The doping of an antiferromagnet can lead to complex physics related to high temperature superconductivity. In one dimension, however, the competition between spin and density sectors is largely absent due to the separation of the spin and density modes at low energy.

### Special CM Seminar, Oren Ben Or, Hebrew University, "Molecular Chiral-based spintronics devices"

As global data accumulation increases at an ever-growing rate, further miniaturization and the decrease of power consumption have the highest priority in the development of our information and communication technologies. Memory technologies available today offer a variety of methods; all have advantages but also suffer from various drawbacks....

### Special Condensed Matter Seminar, Simon Trebst, U. of Cologne, "Spin liquids and (Majorana) metals"

Spin liquids are often dichotomous states, where an electronic Mott insulator harbors emergent itinerant degrees of freedom that form a metal.
