Latest news (updated July 12th):

• How do we count time using stochastic outcomes? Our latest paper provides the optimal answer. Amazing collaboration with Mark Mitchison, from Trinity College Dublin, who brought up this problem during a KITP program last year. 

• Check our preprint on Collisional Thermometry with Gaussian Systems, from former group members Gabriel Alves and Marcelo A. F. Santos.
  
  
• Check out our  latest preprint on Waiting time statistics for a double quantum dot coupled with an optical cavity. This is part of the masters project of Luis Santos.
  
  
• Check out two ultra-cool new preprints from collaborations with the folks at Trinity College Dublin. The first is about quantum unravellings in the mesoscopic leads approach, with the amazing Laetitia Bettmann, and the second is on universal energy fluctuations in inelastic scattering, with the hero Sam Jacob.
  
  
• Our tutorial on Current fluctuations in continuously monitored quantum system is finally published on PRX Quantum. I think I have never been this proud of a scientific contribution before. Almost 2 years in the making. I really think this will be a very useful resource for students in the future.
  
  
• Check out our latest preprint on queued collision models. This is the first PhD paper of Guilherme Fiusa, and the start of an exciting avenue of research in our group, combining classical queuing theory with quantum dynamics.  
  
  
• Our paper on Fisher information rates of sequentially measured quantum systems was just published in NJP. This is the continuation of a very fruitful collaboration with the group of Steve Campbell at UCD, Dublin.
  
  
• Check out our latest preprint on parameter estimation for quantum jump unraveling, another really exciting study on pushing the boundaries of stochastic sensing.
  
  
• Check out our latest preprint on Fisher information rates in sequentially measured quantum systems. This was a fun collaboration with the group of Prof. Steve Campbell, which is part of our broader program here in Rochester, to further our understanding of metrology with correlated stochastic outcomes.
   
• Check out our latest preprint on Conditional no-jump dynamics of non-interacting quantum chains. This is a collaboration with the group of Prof. Dragi Karevski, from Université de Lorraine, in Nancy, France.
  
  
• Our paper on stochastic metrology has just been published in PRR. Really happy with this. It represents an area of research that I am very interested in and which has much that can be explored.
  
  
• Our paper on particle current statistics in driven mesoscale conductors has just been published as a letter in PRB. I’m really excited about this, as I think it represents an important first step in establishing the full counting statistics of mesoscopic leads and realistic strongly coupled quantum systems.
  
  
• Stoked to have our latest preprint out First Passage Times for Continuous Quantum Measurement Currents. We introduce a novel way to estimate first passage times of stochastic processes emerging from continuous measurements.
  
  
• Check out our latest preprint on Patterns in the jump-channel statistics of open quantum systems.
  
  
• Check out our latest preprint on Stochastic metrology and the empirical distribution. This addresses a question that I have had for a long time: how does our ability to acquire information change if the data is correlated.
  
  
• Check out our latest preprint on “What happens to entropy production when conserved quantities fail to commute with each other.” This was a collaboration with the group of Nicole Yunger Halpern.
  
  
• Our paper on nontrivial effects of dephasing in rectification of spin chains has just been published in PRE.
  
  
• Our paper on the Fisher information of correlated stochastic processes has just been published in NJP. This was a great collaboration with Prof. Felix Binder and the amazing Marco Radaelli from Trinity College Dublin.
  
  
• Was a pleasure to give a colloquium at Iowa State University. Thank you to Profs. Raquel Ribeiro and Paul Canfield for hosting me. You can find the slides from the talk here.
  
  
• Our paper on the entropy of the work distribution has just been published as a letter on PRR. Really proud of this collaboration with my friends in Dublin.

• Excited to share our latest preprint on Particle current statistics in driven mesoscale conductors. Wonderful collaboration with Marlon Brenes, Dvira Segal, Jens Eisert, Giacomo Guarnieri and Archak Purkayastha. We extended the mesoscopic leads method, which is very useful in simulating strong-coupling quantum transport, to include the full counting statistics of the particle current.
