KSQM Calendar

KSKM Coffee & Cake Events provide the opportunity for PhD students to interact with distinguished alumni in an informal format and setting; PIs are not present.
 
Thanks to Prof. Ioan Pop, we are pleased to have Lukas to our upcoming alumni event, where he will share his career insights and advice with KSQM members.
 
About Lukas:
Lukas was raised in a small town north of Karlsruhe, but moved to the 'big' city to study physics. He graduated from KIT with a Master's thesis about 3D transmon qubits in 2016. Afterwards he joined Prof. Dr. Ioan M. Pop's Black Forest Quantum Lab (BFQ) at KIT to continue working on superconducting quantum circuits with a focus on harnessing the kinetic inductance and intrinsic non-linearity of granular aluminum (grAl). In 2019 he defended his PhD thesis about granular aluminum superinductors. Following graduation Lukas joined the lab of Professor Leo P. Kouwenhoven at QuTech (TU Delft, Netherlands) to build on his background in cQED and add the intricacies of semiconductor-superconductor Josephson junctions into the mix. Since 2022 Lukas is part of the quantum electronics department at the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig and heads the coherent superconducting quantum circuits group since 08/2022.

We provide an introduction to elasticity theory and related phenomena. The concept of strain and stress will be introduced, and the elastic constant matrix of the six crystal families and their stability will be discussed. We introduce concepts like Young’s modulus and Poisson ratio. As an examples of a static elasticity problem we will discuss the bending of a beam. 
 
We will review the dynamic equations of motion and their boundary condition; we evaluate the phonon dispersions and their dependence on crystallographic orientations. We discuss the method of ultrasound propagation and resonant ultrasound spectroscopy to determine the elastic constants. In addition, we analyze Rayleigh waves, i.e., surface acoustic waves (SAW). 
 
Moreover, we explore the coupling of quantum materials to elastic degrees of freedom. We introduce the observables expansivity, thermal expansion, magnetostriction, Grüneisen parameter and elastocaloric effect, and we discuss their typical temperature dependences. We review quantum phase transitions, i.e., instabilities of the ground state. Assuming a perturbative coupling of elastic and quantum critical degrees of freedom, we discuss the anomalous behaviour of observables close to quantum criticality. In addition, we analyze scenarios of a non-perturbative coupling. Finally, the concept of elastic quantum criticality, where the crystal lattice destabilizes at zero temperature, will be reviewed.

“PhD in physics? You don’t seem like a nerd at all.”
“You’re a woman in biology? Guess that helped with getting research funding, huh?
“Mathematics degree? For teaching, right?”
“Environmental science? I guess you’re one of those climate activists then.”
 
 
We’re all familiar with it: being pigeonholed. Sometimes it’s through casual, subtle remarks, other times it’s direct and hurtful, and sometimes it remains unspoken.
We also pigeonhole others ourselves when we interact with them. Since these labels influence our perception and actions, they aren’t just unconscious biases but have real consequences.
Understanding the mechanisms behind these biases and their potential effects helps us, on one hand, to scrutinize our own biases and avoid acting upon them, and on the other hand, to devise strategies for dealing with situations in which we are unfairly pigeonholed.
In this interactive workshop, participants delve deeper into the topic of unconscious bias. The focus lies on hands-on methods that bridge cognitive knowledge about unconscious assumptions with emotional aspects. Furthermore, participants work on strategies to deal with unconscious assumptions with which they themselves are labeled.
 
Thematic Focal Points
Perception: Exploring how we view the world and how stereotypes form.
Personal Perspective: Understanding my background and its impact on my perception of women.
Stereotypes and Prejudices: Examining the functions of prejudices and strategies for managing them.
Discrimination and Power Imbalances: Exploring the connection between unconscious biases and structural inequality.
Managing Biases: Developing personal strategies for adressing gender stereotypes and other biases. ODER Developing personal strategies for dealing with biases.
